Features of self-adhesive window seals, types, installation

Hello friends!
I haven’t visited my blog for a long time, I have a lot of work. I've set aside an evening to write an article for readers. In general, today we will talk about insulation for window openings. Recently I witnessed in a hardware store how a sales consultant, frankly without understanding the issue, talked about the pros and cons of self-adhesive insulation to an elderly couple.

I stood nearby, listened, and felt so sad at how illiterate the young people were... well, if you work in this field... study everything thoroughly so as not to make a fool of yourself. Well, okay, I grumbled and that’s enough :). In general, I have prepared the material, read it. Maybe it will be useful to someone!

Sealing window openings

We will talk about sealing the window opening, which is necessary for thermal insulation (protects against drafts, prevents heat loss in winter), but not only.

Window insulation maintains a comfortable microclimate in the apartment during hot summers; prevents dust, street odors, and insects from entering the house; dramatically reduces the noise level, which is especially important if your windows overlook a highway or tram line.

First of all, window insulation is necessary for old wooden frames (a high-quality and well-installed plastic window does not always require additional insulation measures).

There is one caveat: in the old days, glass was often installed in the frame using a special mastic, and it tends to crumble over time. The paint on the frames is cracking, and the wood itself is cracking over time. Small cracks should be filled with sealant before laying insulation.

Obviously, the main requirement for window insulation is its quality. When selecting, you also need to take into account the specifics of the cracks on your window - width, shape.

Energy-saving double-glazed windows

The main components of heat loss through the glass part of a window are convection, thermal conductivity and thermal radiation, and the main indicator of energy saving is emission (glass emissivity). That is, a reduced numerical value of the emitter entails a reduction in heat loss. The low emission value of the double-glazed window coating gives it an energy-saving function. They allow short waves of solar radiation to enter the room, but block long waves of thermal radiation from a battery or other heat source from leaving the room. Glass with such coatings is called low-emissivity.

Self-adhesive insulation

Insulation materials are divided into adhesive, groove and self-adhesive.
The easiest way to install is self-adhesive. It can be foam rubber, rubber, made of polyethylene foam or PVC. There is insulation for plastic windows in black, white and brown. The material is quite durable and allows you to seal cracks up to seven millimeters wide.

When choosing self-adhesive insulation for windows, be sure to look at the expiration date. If you buy rubber or plastic insulation, it is better to take a softer one.

Foam or polyethylene (tubular or rectangular) is suitable for sealing gaps up to four millimeters, provided that the gaps are fairly level. Otherwise, you need to pay attention to the brand: up to three millimeters, profile C, E, K is suitable, up to five - P, V, up to seven - B, O.

More on the topic Thermal film for windows

To seal not very wide cracks, you can use a rubber seal; for uneven and wide cracks, it is better to choose silicone, it is more flexible.

Foam rubber

Foam rubber insulation for windows (foam rubber tapes) was used to seal windows for the winter long before the production of insulation was put into production.

The advantages of this material are known to everyone: it is easily compressed (and, as a result, installed), does not injure the surface of the frame, this method is cheap and simple.

There are also disadvantages: foam rubber for insulating windows is not the best choice; even with very good compression, air still leaks through the pores, and it is also not very durable - foam rubber comes off relatively easily.

The second problem can be partly solved by modern rubber-based adhesives. To solve the first part of the cracks (especially in hard-to-reach places), it is advisable to fill them with silicone or acrylic sealant before installing the insulation.

Insulate the slope

It is possible that replacing a double-glazed window or gluing a heat-saving film will not solve the problem completely. If the window installation was carried out incorrectly, then it will not be possible to insulate the window with “small losses” and additional protection will be needed around the perimeter of the window opening. Slope insulation can be done using various materials:

Styrofoam.

Pros:

This material is quite economical and easy to install.
Cons:
Subject to destruction and changes in characteristics with constant temperature changes.

Mineral wool.

Pros:

Fire resistance, environmental friendliness
Cons
: Difficult to install

Penoplex (extruded polystyrene foam).

Pros:

It has better characteristics when compared with polystyrene foam.
Cons:
More expensive than other materials

Important to consider! All of the above options require further finishing.

Sandwich panel.

Insulation tape

Adhesive paper tape for window insulation is sold in any construction supply store or markets, and is inexpensive.
Previously, strips of thick paper were used instead; they were placed on soap. The presence of an adhesive layer on the tape eliminates the need to use soap, and this type of sticking lasts much better. It is usually placed on top of foam rubber.

EPDM – rubber tape. Suitable for sealing uneven cracks of small width. It perfectly seals cracks and withstands temperature changes from minus fifty to plus seventy.

Silicone insulation tape also withstands strong temperature changes and is indifferent to chemical influences. This is a very plastic material, suitable for large uneven cracks.

Vinyl polyurethane has a porous surface. This tape has good dustproof properties, but is not the best option for thermal insulation. Moreover, it is not the most durable.

How to properly glue insulation to windows - All about insulation and energy efficiency

In houses and apartments where plastic windows have not yet replaced worn-out wooden frames, they prepare for the approaching frosts as if they were going to fight a serious opponent - after all, in winter, any crack becomes a source of constant drafts, simultaneously drawing heat out of the room. Even the best heating systems are not able to deal with such leaks and “heat the street”, so window covering has become a real autumn tradition. And only with the advent of thermal tape on the market, the situation noticeably changed for the better.

Until recently, various folk methods were used, such as wet newspaper twisted into a flagellum, rags for caulking cracks, foam rubber, paper strips on kefir, and the like.

A more advanced and convenient option is masking tape, or crepe, but, firstly, by itself it is not capable of providing the proper level of thermal insulation (the cracks still need to be additionally caulked or filled with insulation).

Secondly, the masking tape either does not hold well (if the room has high humidity - for example, in the kitchen), or holds so tightly that in the spring it has to be removed from the window frames along with the paint.

Thermal tape or thermal tape is a modern replacement for the usual masking tape, many times superior to it in its quality characteristics.

First of all, thermal tape is both an adhesive tape and an insulation material, that is, when sealing cracks with it, you do not need to take any additional measures, laying, caulking, and so on.

A standard strip width of 50 mm is enough to reliably seal a gap of up to 1 cm, but if the gap is larger, the thermal tape can be glued in two strips, overlapping.

Heat tape is not afraid of moisture and is resistant to chemically active substances, so it is used in any room, including in the kitchen, where ordinary masking tape (not to mention popular alternatives) begins to lose its properties soon after pasting due to high humidity. lag behind and let cold air into the room.

Moreover, the thermal tape can even be washed! In addition to thermal insulation, this material provides a certain degree of waterproofing of the room, and also increases its sound insulation. The adhesive composition applied on one side of the thermal tape, coupled with its elasticity, allows you to reliably attach the thermal tape to any materials (after cleaning them from contaminants, if necessary).

Sometimes a buyer has a reasonable question: how light, thin, translucent strips of thermal tape can serve as high-quality protection from Russian frosts. However, it must be taken into account that thermal tape is made from polyethylene foam, one of the most effective and environmentally friendly thermal insulation materials.

If we compare polyethylene foam with conventional insulators, then with a thickness of 1 cm, this material retains heat in the same way as 4.5 cm of wood or 15 cm of brickwork; mineral wool gives a similar effect with a thickness of 1.5 cm, expanded polystyrene - with a thickness of 1.2 cm.

In addition, thermal tape can be used in a wide range of temperatures: from -50°C to +70°C, the only condition is to carry out any work with it at a temperature of +1°C (for greater efficiency, temperatures from +10°C are recommended).

Thermal tape is confidently gaining popularity today and is quite capable of soon becoming a leader in its market segment, since useful qualities combined with an affordable price make it the optimal material option for protection from winter cold.

High quality putty

Another good sealant for insulating windows is window putty. This method of insulation was used a couple of decades ago. The putty is similar to hard, rigid plasticine, but if you squish it a little in your hands, it becomes more pliable, making it easy to apply into crevices.

Laying insulation

Whatever materials you choose for insulating windows, it is recommended to glue seals at temperatures above five degrees, so it is better to take care of the tightness of windows in advance, without waiting for frost.

More on the topic: Which is better to choose - single-chamber or double-glazed windows?

First, you need to remove the old insulation for wooden windows, if any, clean the frames from dirt and degrease (gasoline, acetone, alcohol, or any composition based on them will do). It is necessary to glue in places where the sash comes into contact with the frame, removing the protective film gradually as the insulation is laid.

More recently, old-fashioned methods were used to insulate windows. Some people glued newspaper to the windows, and others glued strips of paper.

Cotton wool, tape or paraffin were also especially popular.

Of course, such insulation methods were not only inconvenient, but also ineffective. Everything changed when self-adhesive window insulation appeared on the market.

Silicone sealant

Silicone sealant is suitable for insulating old wooden windows, as it:

• has high strength;
• lasts a long time;
• abrasion resistant;
• withstands temperatures from -80 to 200 degrees;
• has good elasticity, ensuring reliable tightness;
• has a long service life, identical to the operating life of the window.

Silicone sealant is twice as expensive as regular sealant, but the price is justified by the period of use.

To apply sealant, you should:

• remove spatulas, old putty;
• remove the glass;
• sand the frame where the glass is installed;
• apply sealant;
• insert glass;
• paint the spatula;
• apply sealant to the putty on the side in contact with the window;
• insert spatulas, hammer in small nails for better fastening.

Self-adhesive tape

Insulating window structures is a very important process that must be approached very carefully.
Uninsulated windows often cause drafts, which as a result negatively affect the health of residents.

In addition, window openings become the main bridge of cold, which leads to the loss of a large amount of thermal energy.

Today, the market offers a large selection of modern insulating materials that can reduce heat loss through window units.

All these materials are highly effective and very easy to install. Among all the options, it is worth highlighting self-adhesive tape.

It is made on the basis of foam rubber, polyethylene and polyvinyl chloride. On one side, the material is coated with a sticky compound, which allows it to be fixed in a specific place.

Advantages of self-adhesive insulation

This self-adhesive window insulation has certain advantages.

These include:

• Ability to close cracks, the thickness of which can reach 7 mm;
• High resistance to changes in temperature and air humidity;
• Various colors, which allows you to optimally aesthetically fit the tape into the appearance of the window;
• Relatively low cost;
• Possibility to open the doors.

Thanks to these advantages, this material has gained high popularity and demand among the population.

Disadvantages of the material

Unfortunately, duct tape also has some disadvantages. First of all, it is worth noting its fragility. Most often, it lasts no more than one season.

This means that the insulation needs to be updated annually. Of course, if the doors are rarely opened, then the tape can last two or more seasons.

Despite the fact that such material tolerates temperature changes very well, severe frosts can negatively affect its performance properties.

As a result of exposure to too low temperatures, the adhesive composition may lose its adhesiveness. As a result, this leads to the tape peeling off.

The main disadvantage of such insulation is that it cannot be used on modern window structures. This is due to the fact that it can cause significant harm to the performance characteristics of plastic windows.

Vapor barrier device

There are three layers:

1. From the inside - thermal protection prevents heat loss from the room to the street
2. The middle load-bearing insulating layer provides thermal insulation and sound insulation. These problems are solved by polyurethane foam or other porous material. It is rational to include vapor barrier self-adhesive tapes in this inner layer if the window unit is installed in wet rooms - kitchens, baths or showers
3. The outer layer waterproofs the joint and protects against the penetration of cold street air

Vapor barrier tapes are available with a one-sided adhesive layer and double-sided. A one-sided sticker is used if the film is mounted on the side surface of the window frame. Double-sided tape gives an advantage in choosing fasteners: on the frame or in the window opening. According to climatic versions, tapes are also produced in two types - for areas with low winter temperatures - a winter version of the tape, and for areas where temperatures do not fall below +5⁰С - a summer version.

The base for the adhesive layers of the tapes is butyl rubber or metal.

Main types of vapor barrier tapes:

• PSUL, or pre-compressed sealing tape, is used for finishing and vapor barrier of external joints, ensuring a tight connection between the window frame and the external wall. The base material is butyl rubber; the thickness and elasticity of the tapes provide good insulation.
• BC - vapor barrier tapes for sealing joints for dry finishing of slopes - made of plastic or plasterboard. sizing with BC tapes reduces the risk of condensation.
• VM - vapor barrier tapes attached to the window frame, with an overlap, in order to improve the thermal insulation of joints.
• GPL is a polyethylene foam tape, laminated on one side, with metal strips and an adhesive layer over the entire width.

In addition to the main layer of non-crosslinked polyethylene foam, which is 2 mm thick and is waterproofing, the GPL tape has a second layer - both vapor barrier and protective. The thickness of the outer layer is only 20 microns, the material is polypropylene.

GPL tapes are used for all types of door and window blocks as universal ones. They combine two tasks - waterproofing and vapor barrier. The structure of foamed polyethylene is elastic and closed-porous, so the material does not absorb moisture and its hygroscopicity is almost zero. The tapes are flexible and suitable for installation on uneven surfaces. Metal lamination and the quality of the main polymer (polypropylene as a protective layer) determine chemical resistance in both acidic and alkaline environments, and as a result, good durability of GPL tapes.

They produce GPL tapes in standard width sizes of window and door units, width 9; 12; 15; and 20 cm, in rolls of 15 m.

How to choose a ribbon

The choice of self-adhesive insulation for windows must be approached very carefully. The tape is made from various materials and can have different profiles. This is worth considering when choosing it.

If you decide to use a rubber band, it is better to choose the softest one. Thanks to this, the insulation will reliably close all the cracks and reduce heat loss from the window structure to a minimum.

As already mentioned, insulation can have a different profile. When solving this issue, it is worth paying attention to the nature of the cracks.

If the gaps between the frame and the sash are straight, you can use rectangular profile insulation. It can be used to seal cracks up to 4 mm thick.

In other cases, the optimal solution would be materials with profiles of various shapes that resemble letters of the Latin alphabet.

For example, material with an “O” profile allows you to hide uneven cracks, the thickness of which can reach 7 mm.

When choosing insulation, special attention should be paid to the expiration date.

If it has expired, the adhesive properties of the tape have decreased significantly. As a result, this can lead to it quickly peeling off from the window.

Materials you can use

We will look at different options so that you can understand both how to insulate plastic windows and how to insulate wooden frames. These are different types of structures, and working with them can be very different.

I'll start with the simplest solutions, at the beginning of each section it will indicate what type of windows the technology is used for, so that you learn only what suits you.

Option 1 - cotton wool and paper

This is the cheapest insulation for window frames, which is used on wooden structures. The technology involves working indoors, since paper and cotton wool are not intended for outdoor use.

As for recommendations for carrying out work, they are as follows:

Option 2 - special insulation tape

There are two main options here:

This is what the heat tape looks like

• Self-adhesive foam tape. This option can be used both for cracks in the frame and for joints by gluing the material to the open sash. Foam rubber has good thermal insulation properties, so it retains heat well.

Foam tape with self-adhesive layer

As for the application, everything is very simple:

• Self-adhesive insulation is simply glued in the right place. If there is a gap around the perimeter, then the foam rubber can be pushed into it with a spatula. It is important to close all places through which heat is lost and press the material tightly to the surface;

The tape must be pressed tightly to the surface

• The sashes are insulated with foam tape by gluing it around the perimeter. The material can be placed both on the frame and on the sash - wherever is more convenient for you. The protective layer is removed from the tape and it is pressed tightly along the entire length of the joint.

Foam rubber compresses well, so it is often used for frame and sash joints

Option 3 - rubber seal

Can be used on both wooden and plastic structures. Its main purpose is to seal the joint between the sashes and the frame. Thanks to this, heat loss through this part of the structure is reduced tenfold.

If you are figuring out how to insulate wooden windows for the winter, then you will need a universal option that can have different widths. The thickness of the rubber bands is selected for a specific structure, so that after closing the sash the joint is tight.

The seal is simply glued around the perimeter of the frame

As for the rubber tape for plastic windows, it is selected depending on the brand of profile used. Just tell the store what brand your windows are from, and they will give you the right seal.

For plastic windows, special rubber seals with a special profile are produced

Please note that for reliability in plastic systems, the elastic can be glued to both the frame and the sash.

Option 4 - putty or silicone

If the first option can only be used on wooden structures, then the second is suitable for both wood and plastic. The following can be noted here:

• The putty can be used both inside and outside. This is a special composition that is sold in hardware stores and is specifically designed for sealing the joints of glass and frame. Applying the putty is very simple: roll the compound into a thin sausage, which you press against the edge of the window frame, and then form an inclined surface so that moisture drains from the joint;

The putty is easy to use

• Silicone can be used for both plastic and wooden windows. In the first case, it will be used to seal the junctions of ebbs or cracks around the perimeter, and in the second, beads can be glued to the silicone. This will make the connection airtight and prevent the glass from rattling. You can apply the composition to the gap between the bead and the glass if you did not do everything right away.

Silicone does not allow air and moisture to pass through

Tape installation

The installation of self-adhesive tape must be approached very carefully. The quality of its fastening and the effectiveness of insulation will depend on this. Before you start gluing it, you need to carefully prepare the working surface.

To do this, the frame must be cleaned of old insulation and all contaminants. After this, the place where the tape is attached must be thoroughly washed and degreased. You can use alcohol or acetone to degrease the surface.

More on the topic How to make a heated floor on a balcony with your own hands

Once the surface is ready, you can begin attaching the material. To fix the insulation at the line of contact between the sash and the frame, the protective paper is removed from the back side.

It must be eliminated gradually, as needed. To facilitate the installation process, the tape can be pre-cut into pieces of a certain length.

The material easily sticks to the frame. But, complete hardening of the adhesive composition occurs after some time. During this time, you should refrain from frequently opening and closing the sash.

Heat loss through the ceiling

All the heat goes up. And there it strives to go outside, that is, to leave the room. Heat loss through the ceiling in your home is one of the largest quantities that characterizes the loss of heat to the street.

The thickness of the insulation on the ceiling should be 2 times the thickness of the insulation in the walls. If you mount 200 mm in the walls, mount 400 mm on the ceiling. In this case, you will be guaranteed maximum thermal resistance of your thermal circuit.

What are we doing? Walls 200 mm, floor 300 mm, ceiling 400 mm. Consider that you will save on any energy carrier that you use to heat your home.

Modern film

Today you can also find self-adhesive film on the market. This material appeared on the market relatively recently, but has already gained great popularity among the population.

Using such a film, you can significantly improve the thermal insulation properties of the entire window unit. If the tape seals the cracks, then the film reduces heat loss over the entire area of ​​the window opening.

This insulation takes the form of a regular film, which has a special coating on one side. This makes it easy and quick to mount it on a window.

To give it aesthetics and somewhat hide its presence, heating devices such as a household hair dryer are used. When heated, the film straightens and becomes almost invisible.

Its installation can be easily done with your own hands. Unfortunately, such insulation is used only for one season, or rather one period - in winter.

The disadvantage of the material is that it protects the room well from both cold and heat that comes from outside. As a result, in the spring the room warms up very slowly.

To eliminate this drawback, it is necessary to dismantle the film immediately with the onset of heat.

It seems that the modern world is simply unimaginable without new products and inventions; it cannot help but create them due to the urgent need for it. In a modern economy, in repairs or construction, sometimes it is impossible to count the number of useful things that, without exaggeration, deserve their place.

Variety of models

Manufacturers offer several options for hermetic seals. In most cases, rubber and PVC are used as a base. Each of them has a set of characteristics:

• features of installation and fastening to the surface;
• degree of durability;
• the ability to withstand external negative factors.

In popular models, the described factors fully cope with the assigned tasks. Each type of tape has detailed installation instructions from the manufacturer to ensure optimal results.

The following types of tapes are found on the shelves of construction stores:

• self-adhesive (with an applied adhesive layer);
• grooved (designed for installation in cut grooves);
• adhesive (having a surface on which glue is supposed to be applied for fixation).

Each option is selected based on actual conditions and the condition of the window.

Self-adhesive rubber strips

Modern self-adhesive tape for window insulation is made on the basis of rubber, polyvinyl chloride, and polyethylene foam. Plastic materials make it possible to compress such insulation to the required state in order to minimize gaps. During production, various dyes are used that make this element less noticeable against the background of the window.

Different shapes of ribbons

The following colors are selected:

• white;
• brown;
• black.

The tape has not only a decorative difference between different models. It is also differentiated by the possibility of hiding gaps. The most popular versions of its design are capable of blocking gaps from 3 to 7 mm in increments of 2 mm. Each interval has its own index. Although there are no ideal gaps in frames, you can always choose the best option.

Use of foam rubber

You can get rid of annoying drafts spreading from poorly sealed frames by installing self-adhesive foam tape for insulating windows. The product blocks heat from escaping outside the room.

Insulating windows using foam rubber and tape

The main shape for such tapes is a rectangular profile. Among the wide range, it is always possible to choose the most optimal option, since the models differ in the following characteristics:

• dimensions (section and length);
• degree of rigidity (relevant for uneven gaps);
• color range (easy to match the frame from white and beige to gray and black);
• the presence of an adhesive layer (self-adhesive can be applied to one of the sides).

Foam rubber was one of the first to be used for such purposes due to its physical properties. It has a lot of advantages, remaining one of the popular materials with the following characteristics:

• good compression ratio;
• there is no frame injury;
• affordable cost per linear meter;
• easy to install/dismantle;
• copes with the task quite effectively.

However, with all the advantages it has disadvantages:

• with significant differences in the gap, air leaks in;
• has a relatively short service life;
• in cheaper models, this adhesive tape for window insulation is weakly fixed;
• poorly resistant to moisture.

If you need to temporarily get rid of a draft, then foam rubber is a quick and easy way to solve this problem, at least for the winter season.

For ease of installation on windows and joints, it is worth purchasing foam rubber with an adhesive base. This material stays on the surface longer, is elastic enough to last for several seasons and regulates the tightness of the sashes.

Tubular seal

Manufacturers of tapes for insulating plastic windows offer a special variety of these products. It is also made of rubber and polyvinyl chloride. Its back side has options, both with a groove hook and with an adhesive side covered with protective paper tape.

Seals must be checked every year and, if necessary, individual fragments must be replaced.

It is this type of seal that is the basis of the so-called. Swedish system for insulating wooden windows. And although, in essence, we are talking not so much about insulation as about the complete restoration of the thermal insulation properties of a wooden window, it is tubular seals that take on the main role in blocking cracks and cold bridges.

The window is sealed using a special seal made of elastic rubber.

The groove version is more reliable, since a special profile groove is pre-cut on the frame. It is able to keep the tape from mechanical impact, unlike the sticky side of other models.

The main advantages of the material are the following properties:

• it is possible to block possible gaps even 7 mm wide;
• durable prepared material can withstand significant temperature changes from a hot surface in the sun to significant winter frosts;
• There are several color options for different frames;
• the material is affordable;
• During the period of operation, the owner has the opportunity to repeatedly open/close the doors without problems at any time.

This is how the seals are inserted into the gaps

Due to these positive qualities, the film gained many supporters.

It is worth noting the negative factors that the tubular seal has. Most of them refer to models with an adhesive base:

• frequent deformations can disrupt adhesion to the surface;
• temperature changes negatively affect the properties of the adhesive layer;
• Not relevant for all window designs.

You can get rid of the shortcomings of a tubular seal if you choose products from well-known world brands.

Insulation film

It’s not for nothing that they say that everything new is well forgotten old. Insulation film was used back in the 90s of the last century, but then it was ordinary cellophane, which was used to caulk cracks. Today this is an improved canvas that can be easily installed on a window and creates a sealed chamber.

Polyethylene film for thermal insulation

The film is attached to the frame using double-sided tape, stretched and heated additionally to make the tension even stronger. Such manipulations make it possible to create an air chamber between glass and polyethylene, which works on the principle of a thermal insulation cushion. At the same time, the film acts as a heat reflector, preventing heat from escaping. In the summer, everything happens the other way around - the film keeps ultraviolet radiation and heat from getting inside and a favorable cool climate is created in the room.

Why do we need self-adhesive seals?

Its main functions are as follows:

• protection from drafts and wind that enter through cracks in windows or doors;
• protection from moisture, dust, pollen, smoke from the street or entrance, and small insects through cracks in doors or windows;
• reduction of external noise through sealing and complete closing of cracks and openings;
• heat conservation and maintaining the temperature inside the building;
• softening the impact when a door or window is suddenly closed and preventing the appearance of microcracks in structures, extending their service life;
• saving heating costs and energy resources;

Convenient and practical

Small accessories such as self-adhesive seals can help achieve complete tightness of the room.

They proved their practicality by the fact that despite the initial base surface of the doors or windows, be it metal, plastic, or wood.

They are easily and permanently glued to the base, do not require significant material costs, are practically invisible on structures, thanks to the maximum approximation to frequently used color tones, do not deform or damage the surface to which they are glued, after some time they are easily removed, leaving no marks on the windows and doors.

Moreover, modern self-adhesive seals do not absorb moisture and foreign odors, are not susceptible to oxidation, do not deteriorate from sunlight, do not fade, are not susceptible to damage by insects, can withstand temperatures from -60 to +120 oC, and are able to retain their elasticity and shape for a long time even at long-term use.

Interpretation of the data obtained

Thermal imaging devices record a temperature difference of 3 ºC, and this will be displayed on the thermogram as an anomalous zone in a characteristic color spectrum. However, the spectrozonal image itself is not sufficient justification to consider the diagnosed area to be defective.

For all anomalous zones, it is necessary to carry out thermotechnical calculations and then draw conclusions about the state of the objects under study

Therefore, portable thermal imagers come complete with instrumental software for qualitative and quantitative analysis of thermograms, as well as creating reports.

All this means that no special training is required to operate an infrared camera. After studying the user manual, it is easy to independently carry out a thermal imaging test and process the results in the proposed program. After analyzing the obtained indicators, the application will give an expert assessment of the pictures.

In addition, the information collected by the equipment can be transferred to programs for processing statistical data - spreadsheet processors or special engineering utilities, for example, MathLab.

It is also worth noting that the thermal imager may produce incorrect results if configured incorrectly. Similar situations occur when examining surfaces such as glass, glossy tiles, and mirrors.

Infrared radiation from nearby objects will be reflected in these surfaces, which will lead to distortion of thermograms. To correctly determine the temperature of mirror surfaces in thermal imaging devices, it is necessary to additionally adjust correction factors.

Cold radiation, which can be reflected from windows and the roof of a residential building, should also be taken into account. The resulting thermogram may be significantly colder than the actual condition of the house. The quantitative method for analyzing the distribution of temperature fields over the surface of structures does not take into account the emissivity and background radiation of the environment

Moreover, it does not matter whether the shooting is carried out with an IR camera on site or whether the results obtained are processed by software

The quantitative method for analyzing the distribution of temperature fields over the surface of structures does not take into account the emissivity and background radiation of the environment

Moreover, it does not matter whether the shooting is carried out with an IR camera on site or whether the results obtained are processed by software

When carrying out diagnostic measures inside a building, more reliable results are obtained, since external climatic conditions do not affect the surfaces being examined. The final thermograms after processing with appropriate programs correspond to reality.

The use of a building thermal imager allows you to objectively assess the quality of a building’s thermal protection, detect cold bridges and subsidence of insulation, as well as find hidden damage and defects in the installation of window units, doorways, and poorly executed joints of roofs, walls and ceilings.

Infrared diagnostics makes it possible to correctly, and therefore economically, carry out work to minimize heat loss in a residential building, reduce the cost of floor insulation and thermal insulation of other structures.

Carrying out a research procedure will make it possible to correctly select insulation for the walls and ceiling of a private building. As a result, the cost of heating a private home will decrease.

Types of self-adhesive seals

Among the varieties of self-adhesive seals, it is worth mentioning the most commonly used rubber (low in cost, often purchased specifically for wooden structures), foam rubber (made of foam rubber), polyvinyl chloride, polyethylene foam, and the more recently appeared self-adhesive seal made of closed-cell foam rubber (porous rubber).

It is always more profitable to take a self-adhesive seal for the entire living space, which is why they are usually sold in coils or rolls of 40 meters or more.

And they will prove their practicality during long frosty winters and hot dusty days. They perfectly hide any imperfections in geometry in structures.

Products in profiles

Among the most common seal profiles are several:

• O-profile for large gaps (from 3 to 7 mm);
• D-profile closes gaps from 3 to 7 mm;
• V-profile for medium-sized cracks from 3 to 5 mm;
• P-profile for gaps from 3 to 5 mm;
• E (K)-profile for gaps from 1 to 3 mm,
• The C(I) profile closes small gaps from 1 to 3 mm.

Seals come in different colors (the most popular are black, dark brown, white); there are also transparent ones.

Ethylene propylene synthetic rubber

EPDM, a compound of ethylene and propylene rubber (soft porous rubber seal), is most often used in the manufacture of self-adhesive seals, because the material is quite ergonomic and does not deteriorate when exposed to constant loads, which is especially important and necessary for windows and doors.

A special advantage is that rubber is a non-toxic coating that is environmentally friendly for people and the environment. It does not form mold, rot, insects, termites and other pests.

Very wear-resistant. Absorbs shocks, maintaining the durability of structures. Adheres to any surface, used for metal doors and even gates, hatches and cabinets, for industrial purposes - on electrical equipment and ventilation systems.

What should I do before installation?

If you want to ensure that when installing a self-adhesive seal on doors and windows there are no problems leading to its subsequent deformation or dismantling, be sure to follow the pre-installation procedure, namely:

• clean the surface from dust and dirt, wipe the surface with alcohol or acetone and dry thoroughly; visually mark the places where the seal will be glued and the places of contact (on the frame, sash, door or door frame);
• prepare the required length of the seal in advance; remove the protective layer gradually and press firmly to the base; after 2 hours, the glue finally sets to the base, drying occurs in temperature conditions from +5-40 degrees Celsius.

Tubular self-adhesive seal

This article is intended to convey to readers information about how a tubular self-adhesive seal is used, what its features are, the main advantages and disadvantages.

As you know, many apartments in our country still use wooden windows and doors to balconies. Of course, they have some advantages over their plastic counterparts, they are environmentally friendly, and allow air to pass into the apartment.

However, due to the characteristics of wood, any such window or doorway over time begins to let drafts and dust from the street into the apartment. In order to avoid such troubles, it is recommended to use specialized types of products.

Let's take, for example, a self-adhesive seal for windows and doors, which is very popular both in our country and abroad.

Product Disadvantages

Undoubtedly, one of the disadvantages that self-adhesive tubular insulation has is its relative fragility.

As a rule, these types of seals are used for one season, less often - two; in addition, in severe frosts, the adhesive ability of the insulation can be significantly reduced, which can lead to it peeling off from the surface of the frame when the window is opened.

It is worth noting that self-adhesive sealing can only be installed on traditional wooden windows and doorways.

When used on modern plastic structures, you can cause significant damage to the double-glazed window structure, the mechanism for opening and closing doors, the correction of which can seriously hit your wallet.

Product advantages

Installation can be carried out independently, without the involvement of professional workers, and costs the apartment owner much less. The material itself also has a fairly low price and is sold in almost any finishing materials store.

When installed correctly (gluing a single piece to the entire surface of the frame, without cutting into separate strips), these types of seals have a fairly high level of efficiency and allow you to hermetically close gaps from 1 to 7 millimeters, preventing dust and drafts from entering the apartment.

What it is: description

The main materials from which insulation is made are rubber, PVC, foam rubber and polyethylene foam. An adhesive composition, protected with special paper, is applied to one side of the insulating tape. When applying insulation, the paper is removed.

Insulation materials are supplied in the form of cut strips, combined into reels, or in the form of formatted rolls.

Rubber

They are distinguished by the lowest price among analogues. They retain heat effectively and are attached using glue or a stapler. One of the disadvantages is poor resistance to moisture: when water gets on the rubber, the material quickly peels off.

If you buy rubber insulation, then the softest one. Rigid models do not adhere well to the window and allow heat to pass through.

Polyvinyl chloride

Reliable and environmentally friendly insulation, which has good frost resistance and resistance to deformation.

When choosing, it is important to pay attention to the rigidity of the product: overly hard models will not adhere well to the surface. The service life is 2-3 years.

Foam rubber

Safe to use and reliable insulation. In addition to thermal insulation, they provide good protection from extraneous sounds. Foam insulation is supplied in the form of strips. The advantages of such seals include low cost and provision of air flow for the room.

However, in terms of thermal insulation, foam rubber is significantly inferior to PVC and polyethylene foam, plus it peels off from the surface quite quickly.

Figure: the shelf life of foam rubber is 1-2 years.

Polyethylene foam

They are bundles made of foamed polyethylene. They retain heat perfectly, provide sound insulation and even protect against moisture on the balcony. The most expensive insulation materials among those presented. Service life – 3-5 years.

Benefits and Features

The advantages and technical characteristics of self-adhesive insulation include:

1. Frost resistance. Depending on the material from which the insulation is made, its thermal conductivity coefficient varies. However, for all of them it is at a high level: after application, the tape will maximally limit the contact of the room with the environment and prevent the appearance of drafts and cold bridges.
2. Versatility. The insulation is suitable for cracks up to 7 mm wide.
3. Reliability. The material is not afraid of temperature changes, moisture, and chemical influences.
4. High-quality sound insulation. Most types of insulation can not only protect the room from frost, but also from extraneous sounds.
5. Environmentally friendly. The materials do not come into contact with the environment or react with chemicals. Insulation materials are absolutely safe for human health.
6. Convenience. Once applied, the insulation will not interfere with closing and opening windows. And the installation process itself will not require the help of specialists: the owner of the house will be able to insulate the window on his own.
7. Low cost. Compared to other methods, self-adhesive insulation has an optimal combination of price and quality.
8. Variety of colors. Among them are white, black, dark brown, which allows you to choose the material to match the windows, ensuring a harmonious appearance of the finished structure.
9. Fire safety. The materials from which insulation is made are low-flammable and difficult to ignite.

The video shows self-adhesive foam insulation for windows:

One of the disadvantages of insulation is its fragility - the material is enough for one or two seasons. And also that the tape is not suitable for insulating plastic windows or loggias with double-glazed windows.

But this information will help you understand how a mortise seal is used for wooden doors and how installation occurs.

But this article will help you understand how to use foam insulation for windows and how to do it correctly.

But what self-adhesive insulation for metal doors is and how it is used correctly can be understood by watching the video in this article.

Choosing the right option

One of the main points that you should pay attention to when choosing a sealant is its shelf life.

Products with an expired or nearing expiration date may peel off from the surface over time, or may not provide proper sealing at all. In order to check the quality, it is enough to bend the material and evaluate how quickly and accurately it restores its original shape.

When choosing a self-adhesive rubber seal, it is best to opt for softer models. If there is sufficient softness, the material will be able to replicate to a greater extent all possible surface irregularities, thereby eliminating any draft.

Double-glazed windows with a “warm” spacer frame (PVC with aluminum wrapping)

The spacer frame is the “skeleton” of a double-glazed window, which not only gives the geometric shape to the product, but is also filled with an absorbent whose function is to absorb moisture that got into the double-glazed window during its manufacture and penetrated during its operation. Due to broken technology or poor quality of this product, windows begin to fog up and freeze in winter. The presence of such an absorbent is mandatory, otherwise condensation will appear inside the glass unit. Materials from which the frame is made: aluminum profile, less often galvanized or stainless steel and PVC. The metal creates “cold bridges” in the edge zone,

making the window temperature 3-4⁰ C lower and increasing the possibility of condensation. In order to reduce heat loss, a PVC frame with aluminum has been developed. PVC provides improved thermal insulation properties, aluminum ensures adhesion of the material with sealants. For manufacturing, the same material is used as for the PVC profile, which means it has the same characteristics such as service life, color reaction to exposure to UV rays, aging, the same as for window frame profiles.
