Sprayed polyurethane insulation Polynor - reviews

Consumer properties

Like any insulating material, Polynor has a number of advantages:

1. Features excellent heat conservation. These insulation indicators are higher compared to expanded polystyrene and mineral wool.
2. Non-toxic. Consumer reviews about Polinor are quite good, since it is not poisonous and does not require protective equipment when using it.
3. Ease of use. When using POLYNOR, a heat-insulating layer is created, which does not require a frame for fastening. Also, no tools or auxiliary materials are required.
4. Excellent grip. The composition quickly adheres to any surface - brick, wood, plastic, stone, concrete, which significantly expands the scope of its application.

Polynor insulation is very popular due to the fact that it is applied by spraying. This affects better adhesion of different surfaces, even if they are not very smooth. Very often this insulation is used to finish hard-to-reach places, for example, where pipes or cables are laid.

Technical characteristics of polyurethane foam

It has already been written many times in the article that polyurethane foam is an effective material for thermal insulation. But all these words are not confirmed by numbers. Below we will present the technical characteristics of the material confirming its quality.

Let's start with the fact that there are various PPU (polyurethane foam) insulation materials. Some have a closed cell structure, while others have a closed cell structure. The first type of polyurethane consists of almost 92% closed cells, while the second type consists of 50%. These materials differ quite greatly from each other in density and strength, so it is necessary to make a choice in favor of a certain type of polyurethane after studying its characteristics.

Closed cell polyurethane foam has the following technical characteristics:

1. Thermal conductivity coefficient within the range of 0.020 – 0.025 W/μ;
2. Vapor permeability coefficient – ​​0.04 mg/mchPa;
3. Density in the range from 20 to 290 kg/m3, depending on the application technology;
4. It is a highly flammable material of class G2;
5. Able to withstand temperatures ranging from -120 to + 120 degrees Celsius.
6. Open cell polyurethane foam has the following technical characteristics:
7. Thermal conductivity coefficient within the range of 0.025 - 0.03 W/μ;
8. Vapor permeability coefficient – ​​0.08 mg/mchPa;
9. Density in the range from 20 to 290 kg/m3, depending on the application technology;
10. The moisture absorption value, if the material is immersed in water for a day, is 15 percent, which is much better than that of other thermal insulation materials.

The technical characteristics of polyurethane foam having closed cells are several times better. This is the reason why it is preferred in various applications. The main advantage of polyurethane foam with open cells is a high level of noise reduction. Therefore, it is most often used in rooms where it is necessary to provide high noise insulation. As a rule, these are production premises.

Polyurethane foam has the following advantages:

1. Efficiency - a parameter that is one of the main, if not the main, for all thermal insulation materials;
2. Minimum weight, allowing the load on the supporting structure to be minimal. Due to this advantage, polyurethane foam is actively used for wooden houses and attic roofs;
3. High adhesion coefficient of 1.5 kg/cm2 and 2.5 kg/cm2 for wooden and concrete walls, respectively. Roughly speaking, the frame holding the mineral wool will collapse faster than the polyurethane foam will collapse;
4. Ease of installation and speed of application of polyurethane foam coating;
5. Moisture-proof and vapor-proof. After the material dries, a monolithic material is formed that has no joints or cracks. Due to this, steam cannot pass through it and moisture cannot be absorbed, even if the material remains exposed to liquid for a long time;
6. Versatility - using polyurethane foam, you can insulate surfaces that have any irregular shape;

Durability – PUF is a chemically resistant material, is durable and is not exposed to rodents and microorganisms. Therefore, its service life exceeds 30 years.

Popular manufacturers of sprayed polyurethane foam

There are not many manufacturers of sprayed PU - this type of insulation is only gaining momentum. There are 5 most famous ones:

• Polynor – country of origin – Russia. Designed for thermal insulation of rooms, surfaces of various shapes, eliminating the penetration of street noise.

Able to close holes, insulate walls, and eliminate noise interference. The advantage is the elimination of the search for additional equipment and the low price compared to other brands.

Advantages and disadvantages

The material has a number of advantages over other analogues, which justifies the demand for products using it. Here are the main advantages:

• The light weight and flexibility of the springless design makes it easy to transport. The product can simply be rolled up and compactly placed with luggage.
• Production features provide the ability to produce models of any shape and size. The material is used for the manufacture of individual orders.
• The density, flexibility, elasticity and thickness of the product can be easily adjusted during manufacturing. They can be selected depending on the purpose of the element.
• The cost of the finished product can be reduced through the partial use of polyurethane foam. At the same time, filling the corners of the mattress and a thin layer on the springs will significantly improve the sleeping properties of the product and extend its service life.
• Does not cause allergic reactions like natural fillers.
• No dust collects inside the product and no parasites appear.

Based on these properties, the consumer often chooses items with polymer filling. Let's take a closer look at how useful it is to use products with polyurethane foam padding in everyday life.

What harm can PPU cause to human health?

It is generally accepted that orthopedic mattresses that adapt to the shape of the body are beneficial for sleep. Softness and comfort can ensure healthy sleep and good rest.

• In this case, there is a serious danger to the human spine. This is due to the fact that the soft filler does not fix the spine in a straight position, and over time it becomes curved. It is better to choose a mattress for a child with hard natural padding to eliminate problems with posture.
• Similar to similar polymers, the filling for a sofa or mattress made of polyurethane foam is susceptible to moisture, direct sunlight and high temperatures. This may result in parts being damaged.
• Depending on what components were used for production, the product may pose a danger in the form of toxic substances. Their gradual release can lead to poisoning of the human body. You need to be especially careful with cheap goods.
• The ability to absorb moisture can also be an unpleasant aspect. This is due to the fact that dampness can accumulate and drying can take a long time.

Durability of products with polyurethane foam filling

If we compare polyurethane foam with other synthetic materials, we can distinguish products made from holofiber and latex from competitors.

The exact parameters of the product service life depend on the quality of raw materials, manufacturing technology, operating conditions and other factors. The estimated service life of polyurethane foam is at least 10 years.

By comparison, latex products can last longer than 20 years. Hollofiber is considered more durable and its durability under certain conditions can reach 30 years.

How to choose the right filling for a sofa

Since a sofa is a favorite place to relax for all household members, when choosing a sofa you need to be extremely attentive to the density and composition of the filling.

The price varies greatly depending on the properties of the material. Therefore, the budget should be taken into account. The best option may be a combined filler.

Pay attention to the case. If it is removable, you can easily care for the product and change the filler if necessary.

This is always more profitable than purchasing a new sofa.

Disadvantages of polyurethane foam, reviews

Reviews and practice of application most often provide the most objective assessment of insulation. Usually, users are primarily interested in the shortcomings of materials in order to find out what awaits in the future and whether money will be wasted. Each material has its own characteristics, which can also be considered disadvantages; polyurethane foam is no exception.

Which insulation to prefer

Choosing insulation often becomes an overwhelming task for the consumer. There are too many technical nuances that are not obvious at first glance. The heat insulator is specified in the project, but it is difficult to solve the problem on your own.

Every insulation product has disadvantages, which the developer is not aware of or has a false idea due to advertising. For example, the durability of materials, about which very contradictory data are given in different sources, cannot be considered an advantage for many materials.

The eternal question of what to give preference to is best solved by acquiring ready-made reviews, operating experience... Or acting according to the approved documentation...

What is polyurethane foam?

Polyurethane foam is synthesized directly on the construction site by mixing complex components using special equipment. Therefore, insulation services with this material are provided only by organizations with special equipment. Independent use of polyurethane foam is impossible.

As a result of the constant slight expansion of the foamed substance and its hardening, a material with a porous structure is formed, 90 - 95% of the volume consisting of voids in the cells. But the characteristics are unique - the highest degree of thermal insulation among artificial materials. At the same time, the price is moderate. Specific costs for very large volumes are low, i.e. over large areas the material also becomes advantageous.

Individual disadvantage

But the creation of polyurethane foam occurs every time without standards, “like an uncle twisting a pen.” This also entails its big drawback - the characteristics will completely depend on the desire of the creator, his conscientiousness, the quality of the equipment, the quality of the components...

The most important parameter is achieving the design specific gravity - kg/m3. Strength characteristics, thermal insulation coefficient, vapor permeability will depend on this... But the creators want to fill the volume and spend as few components as possible….

Therefore, one of the most important indicators of this material is simply consumer reviews of a particular organization involved in spraying. To avoid negative consequences, independent technical control at the construction site is also important.

Afraid of the sun

The effect of ultraviolet radiation on most synthesized plastics is negative. Irradiation destroys chemical bonds and the structure of the material. Users comment on the shortcoming - “the material turns yellow and shrinks.”

When coating external surfaces, it is not recommended to keep polyurethane foam in the sun without protection. In any case, manufacturers may not focus on this. But reviews of polyurethane foam speak precisely to the need to protect it from radiation.

Can be used under protective putty or paint. True, external use is questionable due to another disadvantage of the material...

No flat surface

A typical area of ​​application for polyurethane foam is in cavities covered by hinged panels. Or in places that do not need aesthetic evaluation. Why panels that are hung on the sheathing?

Because it is not profitable and difficult to apply a plaster and paint layer on top of the material. A too uneven surface is created. Spraying is done individually, as the master can. And the thickness of the layer is determined by the average result, while in some places it can be +- 2 cm.

Vapor barrier - advantage or disadvantage?

Reviews about polyurethane foam say one thing - it is better not to use it on vapor-transparent materials from the outside. The insulation will block the escape of moisture from wood, from aerated concrete, from expanded clay concrete... It is better to use the material strictly in accordance with the design, where the structures are specially designed, for example, vapor barrier membranes are provided.

Doing it on your own can literally lead to disastrous results for the wall (structure) - water will flow from it. Thus, the property of the material to poorly allow water vapor to pass through itself will turn into a major disadvantage if used ineptly...

Destroys and binds

Expansion during the formation of the structure can also be considered as a disadvantage of this heat insulator. Using these criteria, users usually make reviews about polyurethane foam - for example, “this foam brought down half of my wall, I didn’t expect...”

Indeed, in closed cavities the material can cause trouble - it will rupture the shells. For example, when pumping without rules into the cavity of a three-layer wall behind a brick wall, there is a risk of squeezing out the cladding, collapsing...

On the other hand, the material is designed in prefabricated structures on lathing, in panel houses. Here it not only fills the internal cavity of the panels, creates a heat-insulating shell, but also fastens the outer cladding itself, creating a monolith….

What is the downside in case of fire?

The material does not support combustion, but at a high enough temperature it begins to decompose, smolder, and ignite. At the same time, releasing substances that are not at all useful. It is not recommended to use it from the inside in an open form for fire reasons; it is better to cover the polyurethane foam on top with a fire-resistant shell.

Typically, an application in which fireproof walls made of mineral materials, or panels made of gypsum fiber or cement fiber, are located inside the living space.

What reviews say about the durability of polyurethane foam

One of the most important qualities of materials used inside permanent structures, such as walls, is durability. It’s good if the wall can be easily disassembled and the insulation material can be replaced, as for example in a ventilated façade system with hanging panels on the outside. But if the material is bonded to a supporting frame, as polyurethane foam does, and covered with heavy finishing in wet processes, then its low durability is the main drawback.

All synthesized materials decompose and serve less than natural mineral ones. But is durability really short? As far as one can judge the shortcomings that consumers leave reviews about, they do not consider this a disadvantage of the material. Those. Until now, there has been no direct replacement of insulation in terms of service life, its “drying out and crumbling”. But this is possible only because energy audits of buildings, measurements of the heat transfer resistance of structures, neither during creation nor during the process, are not carried out here, as is done in Europe, for example….

Properties and method of application

Polyurethane foam came to us from the West. The peculiarity of the technology of use is that it is supplied to the work site in the form of initial components - isocyanate and polyol. Insulating the house with polyurethane foam, reviews tell us that it is very convenient. To mix these two components and, therefore, directly obtain polyurethane foam, special equipment is used.

Polyurethane foam is applied to the surface to be treated using a special spray gun. After covering the surface with the mixture, the foaming process begins, lasting about 1-2 minutes.

Scope of use

The material in question for insulation, if its composition complies with all safety standards, can be used for finishing both residential and public buildings. With its help it is possible:

• Insulate attic/roof structures of various shapes and types;
• Carry out thermal insulation of floor coverings in public institutions and residential premises;
• Perform insulation of wall ceilings in different buildings.
• Depending on the purpose of the structure, it is possible to propose the following categorization:
• Industrial buildings;
• Outbuildings for various purposes;
• Refrigeration rooms;
• Pipelines;
• Technological tanks and reservoirs for various purposes.

Features of self-application

Most owners of detached housing (and even some large apartments) prefer to apply the composition on their own. However, under certain conditions this process can cause some difficulties. First of all, you need to take care of the availability of special equipment and technical components, namely you will need:

1. Isocyanate mixed with freon 134;
2. Polyol mixed in a cylinder with freon.

These cylinders must be filled so that their internal pressure is at least eight atmospheres. Upon completion of the preparation of the working surface, spraying is carried out directly, for which the spray gun is delicately activated, while its jet is directed exactly to the right place. Due to the fact that the procedure itself is not particularly complicated, more attention should be paid to the selection of cylinders. Insulation for spraying, enclosed in balloons, is considered more preferable and convenient, because it has properly completed industrial preparation and correctly selected internal pressure in advance.

Application technology

Polyurethane foam is often selected for processing the rafter system from the inside, therefore, it can be used not only at the construction stages, but also after all work in the attic is completed. After hardening, the foam will not only insulate the under-roof space, but also form an effective barrier to absorb noise, while simultaneously strengthening the entire roof structure. The applied heat insulator can also be used to insulate the attic, which traditionally has irregular shapes and joints, and is also characterized by the presence of hard-to-reach places. The entire work process will take several hours, but then you will be able to fully enjoy the comfortable warmth during the cold season, and in the summer the room will be pleasantly cool.

In cases where sprayed heat insulation is used to treat residential premises, it can be applied to both internal and external substrates. Thus, in addition to direct insulation, the treated surfaces will be reliably protected from gusty winds, rainfall, temperature changes and other adverse influences. The material adheres well to horizontal surfaces, for high-quality processing of which you will not need a particularly large layer, so the distance between the ceiling and the floor will not decrease significantly.

The process itself is not too complicated:

• The treated surface is reliably cleaned from dust/dirt and slightly moistened;
• A special nozzle is installed on the cylinder;
• Before the first start-up, the container must be shaken gently, and then the spray nozzle must be directed at the surface to be treated;
• By pressing the trigger of the spray gun, a foam jet is released in the selected direction.

Comparative characteristics

The properties of polyurethane foam are most clearly visible in comparison with similar thermal insulation materials:

Insulating a frame house with polyurethane foam is an almost ideal option for attic roofs of frame houses. It belongs to the group of liquid thermal insulation materials. At the same time, it is difficult to name another mineral wool insulation that will have as many positive qualities.

The article discusses all the features and qualities of insulation, as well as several well-founded user reviews. The technical characteristics, advantages and disadvantages described below allow you to make an informed choice of this material and prepare for its use.

The best manufacturers of polyurethane foam

How to insulate yourself?

When starting to build or renovate their home, many people think about insulating it themselves without involving specialists. It's actually possible to do this. The main thing is to know the technology of working with polyurethane foam and strictly adhere to it.

Insulation of balconies and loggias

To insulate a balcony or loggia with polyurethane foam, two main methods are used: spraying and pouring. The first method is classic. It is used to treat any surfaces. Chemical components are mixed in a special apparatus. The machine begins to foam the composition, after which it can be sprayed onto clean, dry surfaces of walls, floors, and ceilings.

Liquid polyurethane foam can also be applied by pouring. To do this you will have to build a sheathing. The material is poured between the surface of the balcony wall and the sheathing. After hardening, it forms a strong, durable coating with excellent thermal insulation properties.

Basement

It is better to insulate the basement from the outside during the construction stage of the house. If this has not been done, you will have to work indoors. To simplify and speed up the process, sheet polyurethane foam is used. The work is divided into several stages:

1. All surfaces are cleaned of dirt, falling pieces of plaster, and mold.
2. A layer of waterproofing is applied. This could be mastic, liquid rubber, bitumen, and so on.
3. PPU panels are laid. This can be done using glue. But for reliable and durable installation, it is recommended to use “fungi” dowels.
4. After this, you can cover the insulation with finishing materials.

If polyurethane foam spraying is chosen as insulation, then waterproofing is not required. The liquid material penetrates into all cracks, reliably protecting it from aggressive influences.

Walls

Wall insulation is carried out both outside and inside the premises. The first method is preferable. This will allow you to move the area of ​​condensation formation outside the room, preventing the destruction of the structure.

For walls it is recommended to use liquid polyurethane foam. It allows you to create a dense protective coating without joints. The polyurethane foam spraying process is divided into several stages:

1. The surface is cleaned of dust and cement deposits. If there are large cracks. They are filled with cement mortar.
2. The sheathing is being made. It is better to use wooden blocks for it. The distance between them should be at least 10 cm.
3. PPU is being prepared. This can only be done after wearing a protective suit. The two main components are mixed in a special apparatus. It will not be possible to carry out work without it.
4. Polyurethane foam should be sprayed onto the walls from bottom to top. The sprayer is kept at a distance of 5-6 cm from the surface.
5. After completing the work, remove the spray nozzle and close the taps on the tanks with components.

It is very difficult to carry out such work correctly on your own. In addition, expensive equipment will be required. For a small private house, its purchase turns out to be impractical. Therefore, it is better to seek help from professionals.

Floor

Polyurethane foam is rarely used for floor insulation. This is due to its low vapor permeability. Often after such work a musty smell appears in the room. This material can only be used if there is a warm basement or basement under the floor.

Reviews from professionals recommend using sprayed polyurethane foam most often. The process of installing it is no different from working with walls. The material is also sprayed into the space between the sheathing. After the foam has completely dried, you can proceed to laying the flooring.

Attics and attics

Insulating the roof and walls of the attic allows you to reduce heating costs in winter and avoid a significant increase in temperature in summer. It is extremely difficult for a novice master to carry out such work on his own. Liquid polyurethane foam will need to be applied to vertical walls, as well as to roof surfaces with a negative slope.

Application of the material is allowed only in the warm season. All windows and doors are covered with plastic film. The first layer of sprayed polyurethane foam should have a thickness of about 15 mm. If necessary, after it has completely dried, additional material is applied.

How long does one Polinor cylinder last?

The spraying area from one POLYNOR cylinder, with a layer thickness of 30mm, is up to 2m? (subject to following the Instructions). In one pass you can apply a layer from 1 cm to 4 cm, in increments of 20 minutes to the previous one, the number of layers is not limited. The thickness of the layer is adjusted by the speed of application. We recommend applying several layers, first the first layer with a thickness of 1.5 cm to 4 cm, then after 20 minutes a second layer, which will correct the shortcomings of the first layer and provide seamless heat and wind protection.

Is it difficult to use POLYNOR insulation for an untrained person?

Nothing like this! Polinor is the simplest and most affordable insulation to use. You don't need any special skills to use it. All you need is a regular gun for polyurethane foam and a POLYNOR nozzle for spraying, supplied with each cylinder (POLYNOR 3D insulation comes with 2 nozzles - a regular and an angled one for application to horizontal surfaces).

What is the difference between sprayed thermal insulation and foam insulation?

Despite their external similarity, these are completely different products in terms of purpose, properties and characteristics. POLYNOR has a low coefficient of water absorption, a predominantly closed-cell structure, does not shrink and remains elastic, adheres completely (without gaps) over the entire application surface. Polyurethane foam cannot be applied to the surface with a wide spray like POLYNOR insulation; there is no foaming.

How does POLYNOR differ from other sprayed insulation materials?

The formula of POLYNOR insulation has been developed and tested for several years. The product itself has been produced since 2014 and during this time there have not been a single complaint. All other “sprayed” insulation materials are ordinary polyurethane foam; they are characterized by: low foaming, impossibility of application to the roof or ceiling, holes inside the insulation, lack of adhesion (sticking) and the worst thing is that you do not see this incomplete adhesion on the surface ( dew point in the wall). Beware of fakes, so as not to get a problem in the form of poor-quality insulation (fungus, mold, freezing, and so on)!

Is it possible to insulate an apartment with polyurethane foam spray?

POLYNOR insulation fully complies with uniform sanitary, epidemiological and hygienic requirements. Allowed for heat and sound insulation of apartments, attics, cottages, verandas, attics, loggias and so on. Eco-friendly? Does it attract rodents and insects?

RO!UMOV insulation is a biologically inert material, absolutely environmentally friendly. Does not react with water or air in the temperature range from - 80° C to + 115° C. Does not contain freon, formaldehyde and other harmful substances. Rodents and insects perceive POLYNOR insulation neutrally.

Why does POLYNOR have such a price?

The principle of choosing insulation should be based not on its cost and manufacturer, but on its technical characteristics and taking into account all additional costs.

What are the advantages over extruded polystyrene foam and mineral wool?

WITH POLYNOR YOU DON'T NEED:

1. Smooth surface
2. wind/waterproof films
3. membranes
4. mechanical fastener
5. glue
6. cutting out insulation to the required area
7. freight transport
8. qualifications for installing insulation
9. a large sum for the purchase of a large volume of thermal insulation at once

Can it be applied to wood?

Unlike polystyrene foam and EPS, it is ideally combined with wood. Forms a monolith with the surface, which eliminates the penetration of moisture and the formation of a breeding ground for the appearance of fungus and mold. The tree will not rot.

I'm afraid of the dew point, where will it be when using POLYNOR?

Features of the physico-chemical properties of POLYNOR Insulation (low thermal conductivity and monolithic properties) allow insulation with this product both outside and inside premises. If the thickness of the insulation is chosen optimally, the dew point will be in the insulation itself. The wall will remain absolutely dry throughout the entire cold period; even with a sharp cold snap, the dew point will not reach the inner surface of the wall. In both cases, the dew point will be in the insulation and condensation will not form. Condensation forms when warm air and a cold surface collide. Due to the low thermal conductivity and solidity of the material (with sufficient thickness of the applied layer) both inside and outside the room, the temperature of the insulation layer and the application surface with which it comes into contact will be the same.

Is POLYNOR afraid of water?

No, POLYNOR insulation does not react with water that gets on it, vapor permeability and water absorption are close to zero. But, if POLYNOR is constantly in water, it will absorb some water over time.

What is the density of POLYNOR?

19 - 25 kg/m? at a temperature of 22° C and a relative humidity of 65%.

Flammability? When burned, does it melt and release something harmful?

POLYNOR does not support combustion. Flammability group according to GOST 30244-94 - ГЗ (normally flammable). If it is necessary to reduce the flammability group to G2, fire retardant impregnation POLYNOR Polyguard is used (applied to only released POLYNOR, during the first 5-8 minutes after application, consumption 1 liter per 10 m”).

It is impossible to ignite with a gas torch.

Service life of sprayed polyurethane foam insulation?

The applied POLYNOR insulation is closed-cell polyurethane foam, the service life is up to 50 years, subject to operating conditions.

What materials can Polinor be applied to?

POLYNOR is a unique insulation material and is compatible with all building materials, with the exception of membranes and films. Can it be applied to vapor and waterproofing films? No, because they do not have a rigid fixation to the surface.

Can it be used as waterproofing?

POLYNOR insulation is not a complete waterproofing that stops leaks in the roof or walls.

Can it be used as soundproofing?

Yes, the sound absorption coefficient is 55 dB.

How quickly does it dry?

Surface film formation - 4 min. Curing speed (time between layers) - 20-40 minutes. Complete polymerization occurs within 24 hours.

At what temperatures can it be used?

Surface temperature from +5°C to +30°C

Cylinder temperature from +18° C to +25° C

Can it be poured into voids?

It is possible, but only between hard materials (concrete, brick), to prevent them from being squeezed out by the product.

Which gun is suitable and where can I buy a POLYNOR spray nozzle?

The nozzle that comes with each cylinder is suitable for almost any professional spray foam gun, the main thing is that the nozzle is tightly put on and does not rotate on the gun. When spraying, the product must not escape from under the nozzle.

Is it necessary to moisten the surface before/after spraying?

Before application, only porous building materials, such as brick, foam blocks, gypsum, concrete, wood, should be moistened. Smooth surfaces such as metal, glass, etc. - are not moisturized. Thoroughly degrease galvanized metal and corrugated sheets before work. It is recommended to lightly moisten the surface of the released POLYNOR insulation during the first 8 minutes.

Is it necessary to cover/cover the sprayed surface?

It is necessary to protect from UV radiation with finishing or paint (except for water-based and acetone-containing ones).

Is it necessary to leave a gap between POLYNOR and the sheathing?

Need to. POLYNOR is a closed-cell polyurethane foam, so the insulating layer can expand when heated. It is necessary to leave a gap of 2-3 cm between the surface of the hardened insulation and the final finish.

How to properly apply polyurethane foam to a smooth galvanized sheet?

We do not recommend applying POLYNOR insulation to galvanized steel if you do not fully follow the instructions.

The application procedure for galvanizing is as follows:

1) Clean from dust and dirt.

2) Degrease.

3) Wipe thoroughly dry.

4) Apply POLYNOR according to the instructions.

What is the technology for using POLYNOR for external wall insulation (wood, brick, concrete, foam blocks)?

POLYNOR is destroyed over time by ultraviolet radiation, so it is necessary to cover the applied POLYNOR with siding, panels, imitation timber, etc.

1) It is necessary to secure the guides on which siding or other finishing materials will be installed.

2) Moisten the wall a little and spray according to the instructions. Leave a gap of 3-5 cm between the panels and the insulation. Polinor has a closed cell, so the insulating layer may slightly expand when heated.

3) 24 hours after spraying, you can sew up panels.

Can I plaster?

It is not recommended to plaster the layer applied outside the room, since POLYNOR insulation has a closed cell, which expands slightly when heated. Insulation applied indoors can be plastered, but it is advisable to use thermal plaster.

The difference between polyurethane and polystyrene

The closest analogue of polyurethane foam is polystyrene foam, which has similar characteristics and is also used for insulating various surfaces.

Expanded polystyrene belongs to the group of slab insulation materials that are made by foaming. Expanded polystyrene also has many advantages compared to many other slab insulating elements. But at the same time, the functionality of this material is slightly limited when compared with polyurethane foam.

Expanded polystyrene cannot be used for spraying pipes, ventilation ducts and, in general, any elements that have complex geometry. But at the same time, you can apply this material yourself, whereas this cannot be done with polystyrene foam.

To apply PPU foam, it is necessary to use special equipment, which, as a rule, is only available to construction teams of workers. Of course, there is an option to apply polyurethane foam using small cylinders, but it will not be effective if it is necessary to apply insulation over a large area.

Disadvantages of insulation

During the formation of the mixture, a large volume of carbon dioxide or freon is released. It is necessary for foaming and can be harmful to health. Therefore, work must be carried out only in special clothing using personal protective equipment - a respirator and goggles.

Additionally, it is necessary to take into account the following disadvantages of polyurethane foam when using it as insulation:

• The material is destroyed when exposed to sunlight. After its application, a protective decorative layer is installed.
• Difficulty in replacing damaged areas. To do this, you will need to rent equipment again. Repair costs differ slightly from spraying a new layer.
• High price. It consists of the price of equipment and consumables. This insulation is not recommended for thermal insulation of small areas - the smaller the amount of work, the higher the cost per 1 m².
• It is impossible to form an air gap for ventilation between the polyurethane foam and the decorative coating.

Despite these disadvantages, foam insulation is recommended to be used to form a protective layer in large volumes.

Polynor insulation: characteristics

In our previous article we talked about Izba basalt wool. Today we will talk about a modern material, which, according to forecasts, will soon become one of the most used in civil engineering.

We will talk about sprayed Polynor insulation (one-component polyurethane).

We will help you understand the technical characteristics of this material, methods of its installation and conduct a short comparative analysis of liquid thermal insulation.

Polinor is sold in pistol cylinders.

Polynor spray insulation is a one-component polyurethane composition that is sold in cans similar to polyurethane foam. The similarities between these two materials are not only in packaging, they are also very similar visually. This is where their commonality ends.

Polinor insulation, according to reviews, has surpassed even polyurethane foam. Material characteristics:

• thermal conductivity 0.025 W/mK;
• water absorption no more than 0.03% per day;
• low vapor permeability;
• density 18-28 kg/m. cube;
• flammability group G3 - a normally flammable substance, at 120 degrees it begins to collapse.

One cylinder of Polynor sprayed insulation, according to reviews, is enough for one square of the treated surface if the thickness of the thermal insulation is 5 cm.

It must be taken into account that the material increases in volume after application. This process occurs as a result of contact with air. The higher the air humidity, the more intense the reaction occurs. This is a material with a closed cell structure.

The number of closed cells reaches 70%; they are filled with ordinary air. Polinor insulation, the characteristics of which allow it to be used without additional hydro and vapor barrier, is afraid of direct sunlight.

We invite you to familiarize yourself with: Bath insulation: price, characteristics. Buy insulation for a bath in Moscow with delivery

Just like regular polystyrene, it does not tolerate a humid environment and is destroyed by constant exposure to water.

One-component polyurethane foam has excellent adhesion to any surface, it does not peel off or break. Polynor insulation, according to reviews, is very elastic, so even if a crack appears in the structural elements, it will not appear in the thermal insulation. In addition to preventing heat loss, this material absorbs sound and vibration waves. It is non-toxic.

If you install combined heating, then the probability of being left without heat in winter approaches zero.

You will find everything about heating a house with diesel fuel with reviews from experienced people in this article.

Working with sprayed insulation is very simple.

• skirting boards and fillets, decorative stucco;
• thermal insulation - both sprayed and in the form of shells and sheets;
• packaging materials;
• molds for the production of artificial stone;
• adhesives and sealants;
• as a basis for the production of paints;
• as an additive to almost all modern coatings;
• as sealing connections.

• low thermal conductivity;
• resistance to various chemical agents (except hydrochloric and nitric acids, turpentine, chlorine, acetone);
• resistance to abrasive influences;
• durability;
• resistance to atmospheric influences, including ozone, ultraviolet radiation and sea water;
• wide range of operating temperatures - from -60 to 100 degrees;
• excellent dielectric properties;
• ability to withstand fairly high working pressure.

And if you consider that the material is environmentally friendly, then its popularity becomes quite justified.

In the production of the material at the dawn of its inception, two substances were used: polyisocyanate and polyol. Depending on the proportion in which these components are used and the reaction rate, the technical characteristics of the final material can vary quite significantly.

• Perlon U - flexible, elastic, but poorly resistant to tearing forces (foam rubber);
• Igamid U is hard and durable, but cannot withstand bending loads.

Modern polyurethane foam is a material with a cellular structure, in which 85-97% of the volume is occupied by pores filled with gas or air.

The very substance that forms these pores makes up only 3-15% of the total volume of insulation. Therefore, polyurethane foam is a very light material.

• for soft material – 5-40 kg/cu.m. m;
• for hard – 30-86 kg/cubic. m.

• thermal conductivity is 0.019 - 0.03 W/m - the lowest of all thermal insulation materials;
• the solid type of polyurethane foam has a large number of closed pores, which significantly increases its acoustic impermeability and allows the material to be used as sound insulation;
• a high adhesion rate allows the material to be applied to surfaces of any configuration without using additional fasteners;
• the resulting coating is very durable and does not suffer from exposure to precipitation, aggressive atmosphere of industrial production, pests, microorganisms (however, prolonged exposure to sunlight should be avoided).

The neutrality of polyurethane allows its rigid form to be used as thermal insulation for food refrigerators, and its elastic form as furniture padding and filling for children's toys.

PPU with a density of 70 kg/cubic. m practically does not allow water to pass through and can be used as waterproofing.

• construction industry – about 50%;
• instrument making and refrigeration industry – 20%;
• space, rocket, automotive, furniture and other industries - the remaining 30%.

The material has become very popular as thermal insulation for main pipelines of large diameter and length. In this area, it not only reliably protects pipes, but is also rarely subject to vandalism - because it simply cannot be stolen for reuse.

In the medical industry, the material is used for the production of orthopedic shoes and prostheses.

• Substance A is intended to support the reaction of component B. Its composition includes: foaming components, foam regulators, catalysts, polyesters, fire retardants. Supplied as a brown or yellow liquid.
• Substance B is an isocyanate, which upon contact with air begins to polymerize.
  It is a brown liquid with a pungent odor.

When substances A and B are mixed, a chemical reaction begins, accompanied by the release of a large volume of carbon dioxide, which foams the material. After hardening in air, a layer of insulation is formed with a large number of closed small cells containing carbon dioxide.

The mixture is sprayed using special equipment.

• Easy application of the mixture to any surface in a continuous sealed layer without the formation of seams. This way, you won’t have to worry about possible cold bridges.
• Being hydrophobic, it perfectly protects any structures, including metal ones, from corrosion (it doesn’t even need to be painted).
• Excellent adhesion allows the material to be applied to any surface, even smooth (cleaned of debris, dust and grease stains).
• After polymerization, polyurethane foam acquires high strength, allowing it to be used, among other things, for insulating basement floors and foundations.
• Although polyurethane foam is not a non-flammable substance, the addition of fire retardants to component A allowed it to be assigned a fire safety certificate G2 (poorly flammable self-extinguishing materials).

But, having decided to use polyurethane foam for thermal insulation of a house, you need to know and take into account its disadvantages.

• The need to use special equipment to carry out the work.
• Low resistance to UV rays, dictating the need to protect the insulation layer.
• When applying the material, a large amount of carbon dioxide is released, which is harmful to humans, so during work you will have to use a respirator and skin protection.
• Quite a high cost of thermal insulation.
• Due to the large number of closed pores, the material practically does not “breathe”, so natural filtration of air through the structure of the house will become impossible.

• roof;
• walls;
• floors;
• attics;
• partitions.

Moreover, for each type of structure, a material of different density (and therefore weight) is used.

PPU helps not only to insulate structures, but also to strengthen them, as well as protect the house from excess noise.

Polyurethane foam insulation, which is applied by spraying, is divided into two categories: industrial - sold in barrels and used by specialists to insulate large structures and surfaces, and in 1-liter cylinders, which are intended for independent use. Industrial polyurethane foam is represented by several brands from different manufacturers.

• Sealection 500 is an American made material. It has an open structure and fire safety class G2.
• “Ecotermix” is produced on the basis of vegetable oils and contains a minimum amount of harmful substances.
  There are two varieties of it on sale: grade 300 - with a closed structure to protect external surfaces from cold, and grade 600 - with an open structure for interior work.
• Healtok Soy 200 is a closed-structure insulation material made from soybean oil and polymer waste.
  Adheses perfectly to any surface, tightly fills all cracks and pores.

We suggest you familiarize yourself with: Construction insulation for walls

Polyurethane foam in cylinders is made from polymer components. The cylinder has a spray tip or an adapter for use with a mounting gun. Currently, this insulation is presented on the market in two brands - Polinor and TEPLIS.

The material looks like polyurethane foam. After hardening, it forms a fine-mesh coating with low thermal conductivity. One cylinder is enough for 1 sq. m of surface when applied in a layer of 40 mm.

• Surfaces must be cleaned of dust and dirt and slightly moistened.
• You need to screw the nozzle onto the cylinder.
• Then it is shaken and the nozzle is directed to the desired location.
• By pressing the trigger of the gun, the material is sprayed.

Currently, insulation in cylinders is heavily advertised, but experts do not advise trusting advertising too much.

Although it is claimed to have a service life of 35 years, it has not yet stood the test of time.

Manufacturers of industrial two-component insulation believe that one-component polyurethane foam in cylinders is practically no different from conventional polyurethane foam, but costs several times more. The material has a large number of open pores, therefore it is unsuitable as a hydro- and vapor barrier.

2 Features of installation of sprayed thermal insulation

In terms of the complexity of arranging insulation, Polinor foam insulation differs from rolled and slab thermal insulation materials for the better.

Using PPU Polinor can perform thermal insulation of any surfaces: horizontal – floors, flat roofs; vertical and inclined – walls, facades, roofs; and objects with complex shapes - water supply pipes, well caissons, etc.

Insulation with Polinor can be done by one person, without the need for any outside help. Foam thermal insulation is produced in compact cylinders containing enough insulation to cover one square meter (based on the thermal insulation thickness of 6 centimeters).

It is worth noting that such packaging has a positive effect on savings, since it is extremely simple to calculate the number of cylinders required to insulate an object, knowing their productivity.

Before starting thermal insulation with Polinor, it is necessary to carefully prepare the insulated surface. The wall, floor, or roof of the house is cleaned of dust and mechanical impurities.

If any damage is detected in the structure of the house, the defects must be eliminated to prevent their further spread. In case of cracks in brick, concrete, or gas silicate walls, the damage must be repaired with a mixture of glue and cement.

Next, the insulated surface is degreased using any organic solvent - acetone, toluene, 748. This must be done due to the fact that Polinor’s adhesion to an oily surface is much worse than to a clean brick wall.

Preparing the Polinor mounting gun

The PPU cylinder, before starting work, must be stored at an air temperature of 18 to 30 degrees. Before application, shake the container for 2-3 minutes.

Thermal insulation is sprayed using a special gun, which must be purchased separately, since it is not included with Polinor cylinders.

Together with a polyurethane cylinder, you will receive a universal nozzle that controls the flow and supply of PU foam, which allows you to spray Polynor with any foam gun.

It is necessary to mount the nozzle onto the barrel of the gun (until it clicks), after which the cap is removed from the end of the cylinder, after which the gun rod is screwed into the PU foam cylinder, which is in a vertical position.

As a rule, the thickness of the Polinor thermal insulation layer should not exceed 6 centimeters. The foam flow rate is regulated by the pressure of the release handle of the mounting gun. The cylinder itself must be shaken every few minutes of operation (you need to hold on to the cylinder itself, and not to the mounting gun).

When spraying thermal insulation, it is necessary to strictly adhere to safety regulations, since uncured polyurethane foam can cause harm to the human body.

Polyurethane foam can cause irritation to the eyes, mucous membranes, and areas of the skin that it comes into contact with, therefore, installation of Polinor must be carried out in a protective suit, or, in the absence of special protection, use construction glasses and gloves.

Thermal insulation of attic walls with Polinor

Overview of Polynor spray thermal insulation

One of the most effective insulation materials today is polyurethane foam, or PU foam for short.
Manufacturers produce it in the form of plates, foil-coated and sprayed using special mechanisms. Due to technical difficulties and increased cost relative to other insulation materials, polyurethane foam is not widely used. However, now the Norwegian-made polynor sprayed insulation in foam cylinders has appeared on the building materials market, which has significant advantages.

What is polynore

Polinor is a one-component polyurethane foam, which in its thermal characteristics is superior to polystyrene foam and insulation from various types of mineral raw materials, but the main difference between Polinor and polyurethane foam is its compact packaging in cylinders, which does not require either bulky expensive equipment or the involvement of contractors for operation - you only need a gun - sprayer and strict compliance with the manufacturer's requirements. One Polinor cylinder is enough to insulate 1 m2 of area with a thickness of 5–6 cm.

The weighted average price of insulating 1 m2 of sprayed polyurethane foam with the involvement of a team of insulators will be 17-26 dollars, while the cost of a polynore cylinder is 7 dollars, and all insulation work can be done independently.

A sprayed thermal insulator such as Polinor is designed for thermal insulation of almost all types of surfaces:

• Wall structures made of materials such as brick, concrete, lightweight concrete blocks, wood and wood materials.
• Floors and attic floors arranged on joists.
• Internal surfaces of attic and attic slopes.
• Foundations, basements, ground floors.
• Various communications - water supply, sewer, heating pipes.

Unfortunately, the low pressure in the cylinder will not allow the use of foam to fill cavities in the walls of three-layer structures, but when sprayed onto a surface, one insulator can insulate up to 100 m2 of surfaces with polynore per shift.

The strengths of the polynore include the following qualities:

• Cost comparable to other popular insulation materials.
• Easy installation.
• Fast curing.
• No cold bridges.
• Safety for humans.
• Durability – 40-50 years.
• Excellent adhesion to basic building materials.
• Resistance to most solvents and liquid materials used in construction - acetone, alcohol, toluene, gasoline, kerosene, oils, cement and cleaning solutions.
• Efficiency.

Polinor insulation has the following technical indicators:

• Thermal conductivity 0.023…0.025 W/μ.
• Volumetric weight ≥28 kg/m3.
• Water absorption 2%.
• Permissible heating -121 °C.
• Sanitary safety - certified for residential use.

Disadvantages of polynore

Unfortunately, the ideal insulation has not yet been manufactured, and polynore, despite all its positive qualities, has disadvantages:

• Destruction under the influence of sunlight (UV spectrum).
• Not durable when exposed to water.
• Does not withstand contact with hydrochloric and sulfuric acids, methylene chloride, chloroform, dichloroethane.
• The temperature limit during installation is 18... 35°C; at lower temperatures, foam consumption increases significantly.
• Toxicity upon application.
• The manufacturer's limitation on the thickness of the insulation layer is 6 cm.
• There is no vapor permeability; as a result, the insulation does not allow the wall to breathe, which requires forced ventilation in the insulated room.
• To apply thermal insulation, you need to purchase a construction gun with a nozzle.
• Flammability – polynor refers to self-extinguishing materials with flammability group G3.
• Contact with the ground is undesirable; when insulating the foundation externally, waterproofing is required.

Polynore installation

Since the sprayed heat insulator Polynor is toxic during operation, installation of insulation is carried out in personal protective equipment: goggles, suit, respirator, gloves. Before installation, it is important to remove dust from the surface to be treated.

Then the surface is degreased with any organic solvent. Since polynor insulation has excellent adhesion, the evenness of the insulated surface only affects foam consumption. It is also necessary to protect non-insulated surfaces from foam splashes.

The installation of battens and frames for thermal insulation is not required, however, if a curtain wall is planned, the frame for it must be installed before insulation is carried out.

The heat insulator is installed as follows:

• Screw the nozzle supplied with the cylinder onto the barrel of the gun until it clicks, then remove the cap from the cylinder and polynore, and screw the gun rod into the cylinder itself;
• shake the container for 2…3 minutes;
• a stream of foam is directed to the required area.

Without minimal experience, it may be difficult at first to achieve uniform layer thickness, which is adjusted by tilting the gun nozzle. It is recommended to shake the container periodically. After completing the work, the tools must be washed with a special cleaner, since frozen foam is almost impossible to clean.

Polymerization occurs within 40 minutes, final hardening occurs after 3 days. The use of special films and membranes for vapor barrier is not necessary, which also reduces the cost of thermal insulation.

Conclusion

Most of the negative reviews about polynore are associated with performing work at low temperatures, which significantly increases material consumption and the use of an unsuitable construction gun. Polinor is a case where it is necessary to thoroughly follow the manufacturer’s recommendations to obtain a high-quality result.

Sprayed thermal insulation Polinor

Polyurethane insulation Polinor

• Internal walls and facades of houses made of any material - brick, concrete, gas silicate blocks;
• Lag floors, and any coverings with a non-load-bearing structure;
• The inner surface of the pitched roof;
• Attic, attic floor (Astratek liquid insulation is used);
• Foundation, basement, ground floor.

The one-component sprayed polyurethane foam system Polynor (POLYNOR) is supplied in aerosol cans. One aerosol can with a polyurethane foam system is intended for spraying 1 m2 of thermal insulating polyurethane foam coating, 40-50 mm thick. To work, you will need a mounting gun; each cylinder comes with a special attachment for the gun. No compressor needed!

520 RUR560 RUR650 RUR60 RUR

Excellent heat conservation - with Polinor it is better than with expanded polystyrene and is almost twice as high as with mineral wool.

For high-quality insulation you will not need a large thickness of insulation, since the sprayed insulation Polynor (POLYNOR) has high thermal conductivity of 0.023 W/(mK), note that the lower the thermal conductivity coefficient, the higher the thermal insulation characteristics of the insulation. For example, mineral wool - 0.045 W/(mK), fiberglass - 0.040 W/(mK), expanded polystyrene - 0.033 W/(mK).

The insulation has good vapor permeability and does not absorb moisture.

Non-toxic - unlike penoizol and 2-component polystyrene foam insulation, POLYNOR is not toxic and does not require the use of special protective equipment when working, in addition to ordinary glasses and gloves.

Ease of use - POLYNOR, when creating a heat-insulating layer, does not require a frame for fastening, additional tools for work and auxiliary materials. To use it, you do not need special knowledge and skills - therefore, not only a builder, but also an ordinary householder can work with it. This means that the target audience of the product is much wider.

In addition, POLYNOR has excellent adhesion (the degree of adhesion to the surface) and therefore can be used with most building materials - such as brick, concrete, wood, plastic, stone, etc.

But the main feature is different.

This means that POLYNOR can be effectively used to insulate hard-to-reach places and places of complex shape (for example, where pipes or cables are laid). And you can also be 100% sure that there will be NO draft EVERYWHERE in the old masonry, in a flat panel, in a panel joint, or simply on a panel wall.

• facades, loggias, verandas, attics, attics, basements;
• apartments, residential and non-residential premises in houses, cottages;
• production premises and structures;
• pipelines and other engineering communications and systems;
• isothermal wagons, thermos vans and similar vehicles.

• an improved polyurethane foam formula was used;
• an activator ball is placed in the Polynor 3D balloon;
• at the exit from the cylinder, an improved cell geometry is obtained;
• a more even layer of polyurethane foam during application;
• large application area from one bottle.

• Clean working surfaces from dust, dirt and oil stains and moisten.
• The container should be at room temperature (18-35°C) before use.
• Place the special attachment (included in the kit) onto the gun barrel until it clicks.
• Remove the cover from the cross and screw the gun (not included) onto the vertically standing cylinder.
• Shake the container with the gun thoroughly.
• The output is dosed by pressing the trigger of the gun. The spray layer should be no thicker than 5 cm.
• During operation, shake the cylinder with the gun periodically.
• To clean the gun and remove contaminants from the insulation, immediately after completing work and disconnecting the cylinder, use a special cleaning liquid PULP Cleaner.
• Cured NPU is removed using a cleaner for hardened foam PULP Cleaner or mechanically.

Comparison of Polinor insulation with Penoizol

Experienced builders and finishers have already dubbed Polinor insulation a complete replacement for liquid polyurethane foam. At the same time, the final price for surface insulation will be significantly lower than when using polyurethane foam. In addition, when installing polyurethane foam, it is necessary to use special equipment that must be transported, incurring additional financial losses. Using insulation in cylinders, everything is much simpler.

Among the characteristics are excellent vapor barrier. An analogue of polynor polyurethane foam, it transmits steam worse and condenses moisture, unlike insulation in cans

This is especially important when insulating wooden houses

Both materials are non-flammable, this is their similarity, but Polinor has the properties of allowing steam to pass through and remove moisture, while polyurethane foam exhibits worse performance in these properties.

In addition, polyurethane foam is a rather bulky material, which requires delivery costs and additional equipment for application.

To summarize, it should be noted that the modern insulation material Polinor is an excellent means for insulating any surfaces, convenient, with good performance properties, which will last for many years if certain measures are taken to protect the thermal insulation layer.

The ease of installation and good consumption of material, as well as the consumer reviews left about Polinor, win over not only people who decide to do insulation with their own hands, but also experienced professionals who increasingly prefer this modern insulation.

Sprayed polyurethane insulation Polynor - reviews

In the summer I insulated the wooden ceiling in the kitchen at the dacha. The heat began to stay in the kitchen and no longer escaped into the attic through the ceiling. Now I want to also insulate the floor in the kitchen and room. The result from Polinor insulation is very worthy and it is a pleasure to work with it.

With the help of Polinor, we independently insulated the ceiling and walls of the basement. The sprayed layer adheres well to the concrete base, the airy surface visually creates the feeling of a “soft and warm pink fur coat.” We didn’t even expect that we would quickly cope with a large amount of work - 120 m2 in 4.5 hours. Despite the porous structure, the thermal insulation layer is durable.

https://vltop.ru/optovik/polynor/otzyvy/uteplyali-podval-i-perekrytie-491

At first they wanted to order a team of craftsmen with equipment for spraying, but after calculating the total costs, it turned out that applying it yourself is already 2 times cheaper. The basement and the ceiling between it and the house were insulated. Initially we planned to use expanded clay, but it needs to be brought, unloaded, dragged, and covered with all sorts of hydro- and vapor barriers. In general, we decided to save energy and time. It turned out quite well with Polinor.

The apartment is on the first floor. I decided to insulate the floor from the basement so that the cold wouldn’t pull in from below so much. I've heard about spray-on insulation. I googled reviews about Polinor insulation and decided to try it. In about 3 hours I foamed the entire required area (about 36 sq.m.). I liked everything, I just need to ventilate it, otherwise I might collapse from the stench. It is difficult to ventilate a basement, so the speed of work was a big plus.

Back in the spring I decided to insulate my loggia. As usual, I bought polystyrene foam, clips, etc. in the old fashioned way. But things didn’t work out..))) Some kind of crap turns out. In general, I’m not a builder and I’ll probably never become one) One friend recommended insulation in cylinders, it’s called Polinor. I bought 4 cylinders at the Hertz market. By the way, it is very similar to ordinary polyurethane foam, only reddish in color (the base is polyurethane foam). 30 min. and everything is ready. It turned out that there was nothing difficult, even my wife could handle it))). So I recommend it for those who don’t want to bother and do everything quickly. I'm thinking about insulating the garage too.

My first acquaintance with Polinor took place 2 years ago. Since then, I always use it when I want to insulate something. Recently completed work on insulating a house, cottage and brick garage. There is only one attic left. My opinion is that Polinor is one of the few thermal insulation materials that has a reasonable price and high quality."

Advantages:

There is no need to purchase additional materials, such as lathing, plastic film, fasteners, glue, reinforcing tape.

Flaws:

Adverse effects on Polinor from direct sunlight

I am engaged in low-rise construction. I use polynor as insulation. Designed for insulation of any buildings and structures. It's easy and quick to work with. Its characteristics are in many respects superior to many thermal insulation materials. Unlike polyurethane foam, it easily fills hard-to-reach places, there are no joints or gaps, it is environmentally friendly, reliable and affordable. Those who have not encountered it - be sure to try it, I recommend it!

Siding or plaster?

If polyurethane foam is applied under siding, then the creation of a curtain façade based on a frame and brackets on the wall is required. When applying the material, you need to ensure that it gets under both the frame and the guide profiles. This will provide high protection and reduce heat loss. With this method, the frame should protrude a couple of centimeters above the facade.

If walls are insulated with polyurethane foam for further plastering, a slightly different technology will be required. When spraying, the texture and relief of the wall surface is partially repeated, so the application of polyurethane foam must be done carefully and evenly.

Features of application

Consumer reviews about Polinor insulation are quite common, which is explained by the ease of its use. The principle of working with it comes down to the following:

1. Preparing the working surface for further finishing. To do this, you need to rid it of stains, dirt, and thoroughly moisturize it.
2. The cylinder with insulation must be in the room at a temperature of at least 18 degrees.
3. Before work, you need to put the special nozzle that comes with the kit on the cylinder until it clicks.
4. Remove the cover from the cross and screw the gun onto the base. By the way, it is not included in the package. During this procedure, the balloon must be held vertically.
5. The container is thoroughly shaken.
6. Sprayed insulation is easily applied by dosing by pressing the gun trigger. You need to spray a layer no thicker than 5 cm.

It is recommended to shake the container during operation. To clean the gun after completion of insulation, you need to use a special liquid PULP Cleaner.

Due to its ease of use, Polinor insulation is very popular in everyday life. The instructions for its use are simple, so even a novice user can handle it. As already mentioned, the material can only be applied to a cleaned surface. Moreover, if you are working with a galvanized profiled metal sheet, you must first wipe its surface, remove all stains and oil film, which is always present on the metal due to the peculiarities of the technological process. Heating the aerosol is necessary so that the mass in the container does not freeze and is sprayed evenly.

Application area

Sprayed polyurethane foam has found its place in almost every area:

• large-scale and individual construction - creation of a heat-insulating and waterproof layer (roofing work, blocking the access of cold air through walls, windows, doors, balconies, basements, bathhouses, foundation);
• prefabricated structures - creation of sandwich panels;
• furniture production - the use of an elastic urethane foam layer (foam rubber) in the creation of mattresses, upholstery, seats;
• freezing units – protection against cold leakage for household and industrial appliances;
• pipeline transport – insulation of pipes for various purposes (petroleum products);
• heating networks – preventing hot water supply from cooling down;
• automotive industry - application in the arrangement of car interiors, creation of bumpers;
• equipment – ​​vibration protection of electrical devices, waterproofing of contact connections;
• aircraft construction – protection against heat loss, noise insulation;
• carriage building – fire-resistant materials, noise reduction, thermal insulation properties;
• transport refrigeration equipment – ​​microclimate support;
• design – creation of decorative products, jewelry, stucco moldings.

This material has conquered the whole world. Its ability to stick to almost any surface, even pipes, has come in handy for many. People sleep on it, sit on it, without knowing it.

Popular manufacturers

Polyurethane foam mattresses are produced by different manufacturers. Popular ones include:

Properties and method of application

Polyurethane foam came to us from the West. The peculiarity of the technology of use is that it is supplied to the work site in the form of initial components - isocyanate and polyol. Insulating the house with polyurethane foam, reviews tell us that it is very convenient. To mix these two components and, therefore, directly obtain polyurethane foam, special equipment is used.

Polyurethane foam is applied to the surface to be treated using a special spray gun. After covering the surface with the mixture, the foaming process begins, lasting about 1-2 minutes.

Disadvantages of polyurethane foam insulation

• Compliance with technology directly affects the quality of insulation and the service life of the finished coating. Therefore, work should be carried out by experienced craftsmen using high-quality components and certified equipment.
• Polyurethane foam does not burn in the direct sense of the word, but during a fire the material emits very acrid smoke. This can be dangerous to health and even life.
• Under the influence of ultraviolet light, the hardened foam changes color - from white it becomes dark brown.
• The cost of the service can be quite high. The lowest price per m2 is for lightweight open-cell polyurethane foam, but it cannot be used in all cases.

Cellar insulation: cheap and high quality

When decorating a house or apartment, we look for high-quality materials that are also economical. One of the materials that meets these requirements is Polinor insulation. The price starts from 400 rubles per spray bottle. That is why it is often used when it is necessary to insulate the cellar. When carrying out this work, the dimensions of the foundation and the height of the base should be taken into account. Most often, polystyrene foam is used to insulate the basement, but it is not easy to work with, so many people prefer the more economical option - “Polinor”. The distinctive features of its use include:

1. There is no need to construct a frame, since the insulation is sprayed directly onto the surface. The material fills all microcracks, thereby ensuring reliable thermal insulation.
2. “Polinor” has high thermal conductivity, so it can be applied in a small thickness.
3. Simple installation allows you to do the insulation yourself without using special tools.
4. “Polinor” does not absorb moisture, therefore it serves as an excellent waterproofing layer.
5. After applying the insulating layer, it can be further processed - painted or plastered.

Structure and specificity of the sprayed substance

A sprayed thermal insulator is actually an analogue of polyurethane foam, which is applied to the surface by spraying from special equipment (special cylinders). Such a substance consists of two liquid substances, the mixing of which forms a large amount of foam material, with the help of which certain areas are covered.

The main component of the above substance is polyurethane foam. It is, in fact, a special mixture, the components of which are isocyanate and polyol, i.e. synthetic polymers:

1. The first component is a hydroxyl-containing substance necessary to carry out the reaction with the second component. The solution has a dark brown or yellowish color; its structure may contain various catalysts and polyesters, foam regulators, flame retardants or foaming elements.
2. The second component is isocyanate, has a dark brown color, remains liquid, and has a characteristic odor. When this component reacts with the open atmosphere, the resulting polyurethane begins to harden and become unusable. This shows that the second component must be supplied/stored in sealed containers so that the entire composition is reliably protected from contact with air or moisture (i.e. deliveries are made only in special cylinders).

When mixing the first and second components, their active interaction occurs, which is accompanied by the release of carbon dioxide, which is responsible for the foaming of building insulation. As it hardens, polyurethane creates an insulating layer. Such a layer will consist of a huge number of isolated cells, completely filled with acid. Thus, thanks to this technology, a qualitatively low heat transfer coefficient is formed, which is optimal for insulating surfaces.

Technical properties

The sprayed thermal insulation material is extremely light in weight and can be applied to various surfaces without any difficulties, despite the fact that the applied layer can be of any thickness. Its unique properties are very practical for a certain type of construction and finishing work, which is well known to both novice craftsmen and professionals:

• It is these insulation materials that have the highest thermal conductivity, which can range from 0.020 to 0.028 W/mS. In modern samples of sprayed heat insulators, this indicator is even lower, which makes their use preferable for high-quality insulation.
• Their sound insulation is also at a high level. Such insulation effectively reduces even extremely strong mechanical noise that can interfere with normal sleep and rest of a person, and creates the most ideal conditions for life. From this we can conclude that achieving a minimum noise level can be achieved even when using special instruments with high noise output.
• Sprayed thermal insulation materials have such vapor permeability that they simply absorb moisture, and the amount of condensation simply cannot form in large volumes that could cause harm to the coating.
• The use of this innovative substance allows you to insulate very hard-to-reach places due to its unique consistency.
• Indicators of adhesion to materials (adhesion) are also high - such insulation can be used on almost any surface.
• The speed of insulation work performed with sprayed substances can be defined as record-breaking. To process from 100 to 200 square meters it will take 9-10 hours, and the process itself will not be so labor-intensive;
• Separately, it is worth noting the resistance to interaction with various types of chemically aggressive reagents and biological microorganisms.
• The created coating has an extremely extended service life, and will also be able to successfully withstand precipitation of the same type (for the area of ​​its application) and the aggressive atmosphere of various industrial productions. At the same time, it may not suffer from the activity of biological pests and organisms;
• It should be noted that the polyurethane base with a density of 70 kilograms per cubic meter is absolutely impermeable to moisture, which allows this material to be used as a worthy replacement for waterproofing.

IMPORTANT! Although most experts are not inclined to classify sprayed waterproofing as a non-flammable substance, its first components may include fire retardants, which will make it difficult for fire to spread. Therefore, many types of thermal insulators under consideration have a non-flammability class of G2. In addition to the fact that the substance itself does not support combustion well, the fire retardants included in the structure will contribute to rapid self-extinguishing, which will be ensured through the rapid release of carbon dioxide from the structural cells. The usual material consumption is 890 milliliters per square meter with a layer of five millimeters.

Advantages and disadvantages

The heat insulators under consideration will serve as an ideal barrier to heat loss in the cold season and will help reduce the cost of air conditioning a room in the warm season. At the same time, to create high-quality insulation, you don’t even need to apply an extremely thick layer of the substance - just a few millimeters of a layer of foam will be enough for arranging interior spaces. In addition to the above, the following positive characteristics can be noted:

• The material is applied in a fairly convenient way, by spraying it from a special construction sprayer connected to a compressor. Thus, during the application process and after hardening, an absolutely seamless layer will be created, eliminating the formation of “cold bridges” at the joints and in places where the foam adheres to the load-bearing elements of the surface.
• Due to the fact that polymerized foam does not absorb moisture at all, it is able to withstand a sufficient number of consecutive freezing/thawing cycles, while ensuring proper integrity to the internal structure. As mentioned above, this thermal insulator is able to withstand the effects of many unfavorable factors - from weather to interactions with harmful microorganisms. If the necessary installation conditions are met, the warm layer can last approximately 50 years without losing its useful characteristics.
• The spray-applied layer adheres well to most building materials used, even such as metal or plasterboard. However, before spraying, smooth substrates must be properly prepared by cleaning them from dirt, debris, and greasy stains.
• During the installation process, it is generally not necessary to use lathing, adhesives or any brackets - this circumstance significantly saves the future construction budget. If a decision is made to use lathing, then it may be needed, perhaps, for fastening an external decorative covering, which may include siding, drywall or ordinary lining. From this it can be seen that even a beginner in finishing work can complete the installation without any problems.
• As a result of hardening, the foam gains such strength that it can easily withstand even significant impacts. Accordingly, the substance in question can also be used as a heat insulator for basement floors and foundations of buildings that have a certain depth of depth. And during backfilling and intensive use, the sprayed insulation does not deform, which is also considered an important positive characteristic.

However, like any building and finishing material, sprayed insulation is not perfect and has a number of disadvantages:

• The total cost of 1 square meter insulated by spraying will be significantly more expensive than when using old insulation options - mineral wool or polystyrene foam. Nevertheless, the extremely high quality indicators of using the latest material will allow you to quickly recoup the costs invested in finishing.
• The application process will require special construction and finishing equipment, for which, as a rule, a compressor is used in conjunction with a special device, with the help of which the two components will be mixed. This equipment will have to be purchased separately, however, if the proposed work is not so large-scale, then it can be rented.
• The operator only needs to wear special protective equipment. Despite the fact that after polymerization the substance becomes absolutely harmless to humans, the spraying/foaming process itself is associated with the release of harmful chemicals, so such work should be carried out by a specialist only in a respirator. And to protect the skin from the adhesion of excess foam (which is very difficult to remove later), you should use overalls or other protective clothing.
• The main disadvantage of foam coating is its poor resistance to ultraviolet rays. When exposed to direct sunlight for a long period, the structure of the substance is subject to rapid decay. Thus, the outer layer of insulation should always be protected with decorative material (panels, siding, cement plaster).
