Penoplex insulation - characteristics and application

Production of penoplex and types of material

The production of penoplex is organized using the following technology: small polystyrene granules in a sealed chamber are exposed to high temperatures (1300C-1400C), as a result of which they melt, and after adding blowing agents they foam. Porophores are synthetic additives that, when heated, release nitrogen and carbon dioxide, which, after the penoplex cools, turn into frozen air bubbles, evenly distributed throughout the material.

Comparison of thermal conductivity of penoplex and other building materials

Components of blowing agents for the production of extruded polystyrene foam (penoplex):

Production of penoplex
Cured foam may contain some synthetic fillers, the presence of which determines the direction of application of the insulation - for walls, foundations, etc. The most common additives are flame retardants to increase fire safety (reduce the degree of flammability), antioxidants to protect the material from oxidation in the open air, antistatic substances to relieve static and dynamic stress during insulation operation, light stabilizers (protection from the negative effects of UV radiation), modifying additives and etc.

Polystyrene foam is pressed under pressure from the extruder chamber onto a conveyor for final formation into slabs or blocks. The percentage of gases in the insulation reaches 98% of the total volume of the finished penoplex, so the products are light in weight with impressive dimensions. Dimensions for each functional line of insulation are given in the tables below.

Sizes and types of penoplex

The small size of the pores (0.1-0.3 mm) and their complete isolation from each other guarantees high thermal insulation performance of any brand of penoplex. For different construction projects, it is necessary to select the appropriate series and brands of insulation, since structures can be operated under different conditions:

1. Brand “K” is designed for insulation of pitched or flat roofs and roofs. Specific gravity (density) of the “K” series – 28-33 kg/m3;
2. Series “C” – insulation for internal and external walls with a substance density of 25-35 kg/m3;
3. Brand “F” is used to insulate foundations, basements and basements. Material with high moisture resistance, biological stability and specific gravity ≥37 kg/m3;
4. Penoplex brand "Comfort" is a universal series of insulation with a density of 25-35 kg/m3. Direction of application – insulation of apartments, houses, basements, balconies and loggias;
5. Brand “45” has the highest frost resistance and strength, specific gravity 35-47 kg/m3. Designed for thermal insulation of road surfaces, runways, and other heavily loaded objects and structures.

Expanded polystyrene sandwich panels
A separate category produces sandwich panels, which are an improved thermal insulator for insulating attics and mansards, facades and foundations of buildings. The sandwich panel has 2-3 layers and a cement bonded particle board as the bottom layer.

EPPS Penoplex 20 mm thick

Penoplex 20 mm is an insulation based on extruded polystyrene foam with high heat-insulating and sound-absorbing properties. The material, which looks similar to ordinary foam plastic, has a unique closed cellular structure. This structure allows polystyrene foam to keep cold air and water out and reliably absorb sounds, unlike polystyrene foam.

Description

Extruded polystyrene foam, EPPS or XPS Penoplex 20 mm is intended for thermal insulation of residential, budget and industrial construction projects. The insulation is universal and can be used for insulation and sound insulation of any building elements, provided there are no significant loads on its structural components. These can be walls and internal partitions of the house, roofs, etc.

Durable and moisture-resistant 20 mm Penoplex boards are reliably joined with special tongue-and-groove edges, preventing cold air and water from passing through, effectively protecting the building from the destructive influence of the external environment. After joining, the material does not deform and does not form “cold bridges”. At an affordable price, Penoplex 20 mm will last for many years without loss of technical qualities - the service life of the insulation declared by the manufacturer is at least 50 years.

Penoplex 20 mm insulation is available in several versions, designed specifically for certain areas of its use:

• Penoplex Basis - widely in demand in private construction, universal, used exclusively for non-load-bearing building structures (roofing systems, walls, internal partitions).
• Penoplex Roofing - focused on thermal insulation of roofing systems. Plates with an L-shaped edge ideally fit together into a continuous thermal insulation protection, reliably preventing the house from heat loss and freezing.
• Penoplex Comfort - insulation is used for thermal insulation of flat and pitched roofs, floors, walls and ceilings, the operation of which does not imply serious load.

In addition to the low price, Penoplex 20 mm insulation is characterized by the following positive aspects:

• Low thermal conductivity - extruded polystyrene foam has the lowest thermal conductivity compared to mineral wool insulation and polystyrene foam. This is explained by the specific structure of Penoplex 20 mm - a closed fine-cell structure does not allow air and water to pass through, which eliminates rapid heat loss, cooling and freezing of the material.
• Absolute hydrophobicity - the insulation does not get wet and does not allow moisture to enter the room, even when the material is used in conditions of high humidity. For the same reason, polystyrene foam is not subject to rotting and decomposition processes, remaining unchanged throughout its entire service life.
• Noise absorption - the sound insulation characteristics of Penoplex 20 mm are inferior to Penoplex with a thickness of 50 and 100 mm, but at the same time remain at a decent level. The insulation prevents the spread of impact noise in a residential building, providing optimal acoustic comfort in the house.
• Biostability - by insulating a house with Penoplex, you don’t have to worry that over time the material will be chewed off by mice or it will become covered with mold spores or fungi. The lack of a nutrient medium in the structure of expanded polystyrene foam makes it unattractive to rodents and microorganisms.
• Resistance to chemical factors - the Penoplex structure does not deform when in contact with alkalis, salts, acids and solvents. The material is chemically inert.
• Environmental friendliness - the insulation does not emit toxins and is completely safe when using the material at temperatures from -100 to +75 degrees.
• Durability - at a low price per sheet, Penoplex 20 mm has a long service life - at least 50 years without loss of technological qualities. Such a long service life can be emphasized by the cost-effectiveness of the material - over the years of use, the insulation will not require repair or replacement.

The main disadvantage of Penoplex 20 mm is its high flammability class - G4. The product ignites on contact with an open flame. Therefore, if there are increased fire safety requirements, it is better to buy insulation with NG characteristics instead of Penoplex 20 mm.

Benefits of use

Boards at an affordable price per pack of Penoplex 20 mm help to create a durable, lightweight and continuous layer of thermal insulation in the house, ensuring protection of the residential structure from aggressive environmental factors and comfortable living conditions at any time of the year. It is also important to note the possibilities of sound insulation - the slabs absorb street noise and sounds between interfloor ceilings and indoor wall partitions, guaranteeing an optimal level of silence.

Dimensions of Penoplex slabs are 20x585x1185 mm. When asked how many pieces there are in a package of Penoplex 20 mm, you can answer, only 20 slabs, the covering area of ​​which will be 13.865 m2. The slabs are relatively light in weight, so they are easy to transport even by personal car, which will save on delivery costs. During installation, the insulation does not crumble or deform, showing excellent resistance to fractures. Laying Penoplex 20 mm is simple and does not require special skills or the use of personal protective equipment.

Results of wall insulation with penoplex
Disadvantages of penoplex:

1. Low fire safety - material of any flammability group, even with fire retardant additives, can catch fire and release caustic toxic smoke;
2. Low coefficient of vapor permeability, and under certain weather conditions - negative. Therefore, it is not recommended to use penoplex for internal insulation of house walls. To maintain optimal operating conditions for the insulation, it is necessary to provide forced-air ventilation in the house and ventilation of channels in walls insulated with penoplex;
3. Destruction of the material when exposed to ultraviolet radiation - sunlight. It is necessary to protect the insulation layer with plaster or other methods;
4. Due to the smooth surface, the adhesion of penoplex to mortars is quite low, so the insulation should only be attached to dowels or special expensive glue, but not to mortars.

Penoplex "Wall"

Insulation technology

Penoplex Base is excellent for insulating both floors and walls.

Insulation of a wooden floor with joists

Firstly, all damaged areas on the boards and joists are replaced.
Next, all wooden surfaces are impregnated with antiseptic agents to prevent rotting. Recesses and cracks found on the boards must be filled with special wood putty. Next, all wood surfaces are primed. After the primer has dried, the installation of insulation sheets begins. They are cut according to the distance between the joists and the length of the room and placed on boards.

The joints between the foam boards should remain as tight as possible; they are additionally secured with construction tape. Next, sheets of vapor barrier material are laid overlapping on the foam boards. Boards, plywood or chipboard are attached to the vapor barrier layer. The final stage is the installation of flooring (linoleum, laminate, parquet).

Floor insulation when laid on the ground

When insulating floors in a house with a pile or strip foundation, the method of laying insulating material on the ground is used. First, you need to level the layer of earth and then compact it.

Next, crushed stone and gravel are poured onto the ground. Sand is then poured in and compacted. Penoplex sheets are laid on the sand “pillow”, starting from the corner, pressing tightly.

To protect against moisture penetration, a waterproofing membrane is laid on the foam sheets so that its edges extend 10-15 cm up the wall.

To strengthen the structure, the screed is reinforced with metal mesh. Next, a cement-sand mixture is used for the screed, which is poured over the mesh. Finally, after the cement layer has completely dried, linoleum is laid on it or laminate or parquet is laid.

Insulating the floor under the screed

When using this method of insulation, it is recommended to choose the Foundation modification of penoplex.

Insulation of walls from the inside

Penoplex Base is often used when insulating the internal walls of a house. Firstly, the walls are cleaned of the old coating and a layer of primer is applied. Next, they begin to attach the foam sheets to the walls.

First, the underside of the base foam sheet is passed with a needle roller to ensure better adhesion. Next, an adhesive layer is applied to the sheet, the sheet is applied to the wall surface and held for half a minute.

Gluing begins from the bottom corner, then moving up and to the side. The glued foam sheets are additionally fixed with plastic dowels with an umbrella cap. After the glue has dried, use foam to fill the gaps between the sheets.

Important: recesses more than a centimeter wide must be filled with scraps of foam sheets.

At the next stage, the fiberglass plaster mesh is attached with glue or using dowels. Next, a leveling layer of plaster is applied, and then a finishing layer of putty. Finally, the surface is painted or wallpaper is glued to it.

Insulation of external walls

When insulating the walls of buildings and structures from the outside, it is recommended to use Penoplex Facade, which contains special flame retardant substances to reduce the risk of fire.

Thermal insulation material “Wall” - properties and characteristics

The “Wall” brand is a renamed Penoplex 31 insulation with fire retardant additives, which has been improved for use in insulating “wet” facades, building foundations, plinths and basements, partitions and walls of houses outside and inside, roofs and attics. The characteristics of penoplex brand “Wall” are in the table below:

Penoplex brand "Roof"

Penoplex "Roof" - properties and characteristics

Penoplex insulation of the “Roofing” series is a renamed material “Penoplex 35”, which is recommended for use in insulating pitched and flat roofs of any design. The use of the “Roof” series makes the further operation of the roof as simplified as possible, since the reliability and long service life of the insulation minimize the possibility of repairing the roof surface. The popularity of this innovative insulating material is also due to the fact that greenhouses and summer gardens can be built on such a surface - such trends are now in fashion. Penoplex can withstand such high loads that it doesn’t care about soil loads of up to several tons. Characteristics of the foam insulation brand “Roof” are in the table below:

“Comfort” is a universal brand of heat insulator

Brand of heat insulator “Comfort” - properties and characteristics

Penoplex "Comfort" is a modified and improved "Penoplex 31C" with universal characteristics. The material is actively used for insulating country houses, country houses and cottages. The high speed of installation and minimal labor costs popularize the insulation among private homeowners - it is used to insulate the subfloor, foundation and basement of a house, basement and roof, walls and partitions from the inside and outside of the building. Penoplex "Comfort" has high levels of moisture resistance and thermal conductivity. In the penoplex series line, the Comfort brand is recognized as universal.

Penoplex protects the soil from heaving when it freezes - when the soil is insulated with this material, the freezing point of the soil will rise. This series is optimal for insulating road and railway surfaces, runways and technical areas of airfields. Comfort slabs retain their unique characteristics throughout the entire period of operation. Characteristics of the “Comfort” penoplex insulation brand are in the table below:

It is a misconception to think that penoplex and foam plastic are brother materials. Some properties of penoplex can be equated to the parameters of polystyrene foam, but not flammability and water absorption.

General characteristics of penoplex

Manufacturers have long mastered the production of both non-flammable polystyrene foam and high-burning polystyrene foam. But the truth is that penoplex cannot spontaneously ignite, and in an open fire zone it will only melt, releasing carbon monoxide (CO) and carbon dioxide (CO2) gases. If the fire is extinguished, the penoplex will not even smolder.
