Penoplex: choose the optimal size of insulation

For a comfortable stay in the house at any time of the year, you should immediately take care of its high-quality thermal insulation. She will help out, making the house warmer in winter, and cooler in summer. The construction market provides a large selection of materials for thermal insulation, and each consumer can choose an option to his own taste. The most acceptable insulation in terms of price, quality and ease of installation can be called penoplex.

Plates from foam plastic are similar in their properties to foam plastic, but at the same time they have a number of advantages. The main thing is their high strength and density of the material. Of course, some still prefer the older methods to warm the walls. For example, brick. It is worth mentioning that the foam glass with a thickness of 20 mm replaces a brick wall, in which this figure is 370 mm. And if you compare the plates with a thickness of 50 mm, then the superiority will be even greater: they correspond to the brickwork of 925 mm.

There are three types of material under consideration:

• "Penoplex 31". Due to the low resistance to compression, mainly this type is used for insulating various pipes.
• "Penoplex 35". The most popular type, due to the presence of a special substance that increases the resistance of the material to burning. It is well suited for thermal insulation of enclosing structures and building foundations.
• "Penoplex 45". In comparison with other options, this one is the most durable, it can withstand high loads. In addition to the construction of houses, often Penoplex 45 is used to create roads. This solution prevents swelling of the roadway during freezing, this is especially important when operating the runways. Presented by a narrower range (40–150 mm).

The most versatile insulation. Will be suitable both for the base, and for walls and a roof. Insulation of this category is especially in demand when insulating balconies and loggias. The main disadvantage of the material is its high flammability; it is not allowed to use it in places in which open flame is possible. Its main parameters correspond to the insulation category "31".

It is used for warming underground buildings, foundations of any buildings, as well as the basement of the house. It combines many excellent indicators: minimal water absorption (especially important in areas with surface groundwater), resistance to high loads (for a long time does not subside, more than 50 years). "Penoplex F" is also used to beautify garden paths on a sand-cement foundation.

If we had such wonderful material at our disposal, our ancestors who built the cities, they would have been fortunate enough to build houses insured against their subsequent sinking.There would be no cracks in the walls of the buildings, and the foundation would not be destroyed by the action of soil waters.

When constructing and protecting the foundation with the Penoplex of the “F” series, it will be useful to strengthen the floor screed at home. Here it is important to highlight two points:

1. Strengthening the reinforcement screed.
2. The use of sheets "Penopleks Foundation" at the stage of filling the screed. The dimensions of the sheets will dictate the area of ​​the house: the larger the material, the smaller the joining seams, and hence the less “cold bridges” along which heat will escape from the house. Thus obtained concrete floor will provide increased comfort. It will have a low thermal conductivity due to penoplex, which means it will retain heat inside the house.

Technical characteristics, as in Penoplex Foundation, only the coefficient of compressive strength is lower (the density of the material is 28–33 kg per m3). However, the roof is not experiencing such loads, which fall on the foundation.Due to its low density, the material does not make the rafter system heavier.

This option can withstand the load of plaster, putty, lining. Through the use of such material, you can reduce the cost of heating. "Penoplex Wall" is perfect for exterior cladding of houses made of aerated concrete.

Such material is highly popular among industrial organizations. It is ideal for the floor under the cement-sand screed. Plate thickness varies from 20 to 100 mm.

The table presents the main types of insulation and its characteristics:

After studying the basic parameters and properties of plates from the foam plaster, it is possible to determine its other characteristics and operating conditions. The main technical characteristics of Penoplex include:

• Low water absorption (0.4% when in contact with a wet environment for 24 hours, or 0.5% when in water for about 1 month).Water is able to penetrate only in places damage to the penoplex itself, which are formed during installation.
• Low thermal conductivity (coefficient is 0.03 W / (m * K)). It is provided due to its cellular structure and lack of water absorption.
• Low vapor permeability of the material (0.007–0.008).
• Durability (over 50 years) - not affected by fungus and rotting, but this is only on condition that during the installation of the plates there were no violations of the technology.

• Resistance to thermal factors (provided by the content in the composition of the penoplex flame retardants, which reduce the flammability of the material).
• Wide temperature range of operation (from -100 to +75 degrees).
• Resistance to the action of the mechanical factor - resists compression. At high loads (higher than the performance of a certain type of foam complex allows), small dents up to 1 mm in depth may appear.
• Due to their low weight, foam panels are easy to install. Due to its weight, they can easily be raised to a great height, and they themselves do not make the structure heavier.

Despite such advantages of the material, it is worth highlighting the available disadvantages:

• Despite the sufficient resistance of the material to the action of fire, it still burns (flammability level G3 – G4), while a poisonous gas is emitted;
• The material is unstable to direct sunlight. When it comes into contact with UV rays, penoplex can change its characteristics and also emit toxic fumes.
• Penoplex does not perform a soundproofing function, it must be taken into account during the house insulation.

Penoplex is available as a slab. The dimensions of these foam panels are standardized, with this length varying between 1200 and 2400 mm, with a width of 600 mm. They differ in thickness, which varies from 20 mm to 10 cm (in 10–30 mm increments).

The thickness of the material is determined by the area of ​​its application. So, "Penopleks Foundation" starts from 50 mm. For insulation of internal walls, the thickness of the plates ranges from 2 to 10 cm. When working with internal walls, it should be taken into account that the area of ​​the room will be reduced. Therefore it is worth choosing plates with this indicator of 2–3 cm.

For external constructions, for example, for roofing, 4–6 cm is sufficient thickness. For insulation of external walls, this indicator should be in the range of 8–12 cm.The density of the material depends on the degree of mechanical pressure on the plate.

To choose which penoplex is necessary for you, you need to decide for what kind of work it is needed - insulation of walls, roofs or foundations. A number of parameters should be considered.

• For insulation of foundations, walls, floors - Penoplex Comfort is well suited.
• For wall insulation (both external and internal), plinths, partitions for efficient heat saving and reduction of heating costs - the choice is to stop at Penoplex Wall.
• For the construction of the base of the house or the construction of premises under the basement suitable "Penopleks Foundation", which has high water-repellent performance and increased strength.
• If roof insulation is necessary, there is Penoplex Roofing. It is suitable for both flat and pitched structures. Due to the lightness of the material, the building structure does not become heavier.

Before buying a thermal insulation material, the buyer thinks about its density, because by this indicator one can judge the strength of the material, its weight and thermal conductivity.

• Density "Penoplex Comfort" is in the range from 25 to 32 kg / m3.
• A less versatile type with higher strength can be called Penoplex Roofing. The density of the material is 28–33 kg / m3.
• At Penoplex Foundation, this figure is 29–37 kg / m3. For this type of material, this parameter is especially important. The degree of resistance to mechanical factors (compression) depends on it.
• Penoplex 45 has the highest density, it ranges from 35 to 47 kg / m3.

• The thickness of "Penoplex Comfort" varies from 20 to 100 mm. Each type has its own purpose, for example: penoplex with a thickness of 50 mm is mainly used for insulation of the foundation or blind area.
• The thickness of the penoplex of the “F” series, starts from 50 mm, and it is these dimensional indicators that should be used to insulate underground buildings and the foundation in any house.

• When buying penoplex worth paying attention to the labeling of the goods, the safety of the packaging, the technical characteristics of the material.
• It is worth buying material 10% more from the measured initial quantity, in case it is rejected when used.
• It is necessary to carefully work with the material, since if its integrity is violated, water may get inside, which will shorten the service of the material. It is better to use the services of professionals or get acquainted with the instructions independently and correctly work with penoplex.

• Due to the possibility of toxic fumes being released under the action of UV rays on penoplex, it is considered optimal to use it externally.
• Above the insulation it is necessary to perform the processing of plaster on the grid or other facade material. It is not necessary to cover a heater with a water-repellent agent, because penoplex itself is waterproof.
• It is necessary to be careful when finding other substances near the penoplex. Some of them can destroy the cellular structure of the plate. As a result, its technical performance will deteriorate.

To operate plates penopleks costs in the range of-50… +75 degrees. In this temperature mode, all the characteristics of the material are perfectly preserved.For a long time they can be stored in the manufacturer's packaging, but it is worth protecting from direct sunlight.

When choosing a penoplex, the question is how to make the correct calculations for the raw materials. To do this, on the sites of many manufacturers have a special calculator. It is possible to indicate the area of ​​the insulated surface, and he himself will count the amount of material required.

Before proceeding with the installation of penoplex, you need to complete several points:

• Preparing the work surface, especially important for walls. It is necessary to remove all dirt, smooth the surface of the wall.
• If necessary, it is necessary to process the facade walls with a primer.
• For fixing the plates, a special mixture is prepared having an adhesive base.
• To prevent plates from moving under the action of the wind, they are additionally fixed with fasteners.
