Dimensions of insulation sheet: what is the thickness of penoplex, polystyrene foam and expanded polystyrene

The dimensions of the expanded polystyrene sheet are standard and are usually 1200 * 600 mm, i.e. 120*60 cm. Thickness (height) is of primary importance, since the properties of heat and sound insulation depend on it. The dimensions and differences between foam-based insulation are described below.

The difference between polystyrene foam, polystyrene foam and penoplex

When studying the dimensions of expanded polystyrene, it is necessary to understand what its features and differences are, for example, from polystyrene foam. All 3 materials have a similar composition and purpose - they are used as insulation, as well as for sound insulation.

At the same time, sheet foam is a whole class of raw materials, which consists of organic polymers:

• polyurethane;
• PVC;
• polystyrene and others.

The composition often also contains additional components, for example, phenol-formaldehyde resins. The starting material is granules, which during processing are filled with gas under pressure at temperatures up to 100 degrees. As a result, they increase significantly in volume, and solid sheets are obtained. The dimensions of the foam depend on the manufacturer, but as a rule, they are standard (in millimeters):

• length 500-2000;
• width 500-2000;
• thickness 10-500.

Moreover, both sheet polystyrene foam and polystyrene foam are produced in series, with an interval of 5 mm for thickness and 50 mm for other dimensions. This means that on sale you can find, for example, sheets 1000 mm long, 550 mm wide and 10, 15, 20 mm thick, etc.

A type of polystyrene foam is polystyrene foam. During production, the gas-filled pellets are melted and mixed with another foaming component under pressure. Since this process is called extrusion, the resulting material is called extruded polystyrene foam (EPS). The sizes of EPS can be very different, for example:

• length 600 mm;
• width 1200 mm;
• thickness 20 mm.

Moreover, other intervals are provided here. If we talk about the thickness of penoplex, we can define a range from 20 to 150 mm. The step between these values ​​is 10-20 mm. For example, on sale you can find sheets with a thickness of 20, 30, 40 mm, etc.

As for penoplex (penoplex), this is not a separate material, but simply a trade name for expanded polystyrene. Therefore, its dimensions are exactly the same.

It is clear what polystyrene foam is and what insulation materials are produced based on it. They differ in technology features and partly in composition, but the dimensions are approximately the same. In this case, the thickness of expanded polystyrene usually lies in the range (20-150 mm). There are also thinner sheets of 10-15 mm, but they are quite fragile. If the product is thicker than 100 mm, it is inconvenient for installation.

Dimensions of expanded polystyrene (penoplex)

When choosing a material, it is necessary to take into account not only its dimensions, which is especially important during construction, but also its density.Two important parameters depend on the latter: the larger it is, the more durable the material and the better it protects from the cold. However, too dense products create additional load on the structure - this must be taken into account when insulating the ceiling and roof.

The dimensions of extruded polystyrene foam depend on the manufacturer, as well as on the purpose of the material. To insulate walls and floors, as a rule, standard products are produced with a length of 600 mm and a width of 1200 mm, while the thickness can vary greatly (20-150 mm). The largest sheets are produced for roof finishing - their length and thickness are exactly the same, and their width can reach 2400 mm, i.e. 240 cm.

Penoplex Comfort

The material is often used for finishing apartments and private houses. Its density is in the range of 25-35 kg per cubic meter. The dimensions of this type of extruded polystyrene sheet are as follows:

• length 600 mm;
• width 1200 mm;
• thickness from 20 to 150 mm.

Penoplex Foundation

This is a fairly durable material that is suitable for insulating foundations and basements. Its density is 29-33 kg per cubic meter. The dimensions of the sheet of extruded polystyrene foam Foundation are as follows:

• length 600 mm;
• width 1200 mm;
• thickness from 20 to 150 mm.

For pitched roof

They also produce a special material for finishing the roof of a pitched structure. Its density varies from 26 to 34 kg per cubic meter. If we talk about the thickness of penoplex, then it is standard - 20-150 mm. Moreover, the parameter for specific products is as follows:

• 20 mm;
• 30 mm;
• 40 mm;
• 50 mm;
• 60 mm;
• 80 mm;
• 100 mm;
• 120 mm;
• 150 mm.

As for the basic dimensions of the EPS sheet, the standard length is 600 mm, and the width comes in 2 types: 1200 mm and 2400 mm.This is not always convenient for installation, but it allows you to cover a large area at once and speeds up the process.

Penoplex Facade

Size of this type of polystyrene:

• length 600 mm;
• width 1200 mm;
• thickness 20-150 mm.

Density in the range of 25-32 kg per cubic meter. The peculiarity of this material is its rough surface, to which plaster and painting compounds adhere well.

Penoplex Wall

As you can see, the dimensions of the foam sheet and penoplex sheet are approximately the same, but differ in density. In the case of foam plastic, it can be from 7 to 25 kg/m3, and, for example, the density of Wall foam is in the range of 25-35 kg per cubic meter. Moreover, the dimensions of polystyrene for insulation are as follows:

• length 600 mm;
• width 1200 mm;
• thickness 20-150 mm.

Penoplex GEO

This material is characterized by increased strength and has a density of 29 to 33 kg per cubic meter. It is used mainly for finishing structures located at depth and subject to constant load, for example, for foundations. Standard dimensions:

• length 600 mm;
• width 1200 mm;
• thickness 20-150 mm.

Penoplex Roofing

Another type of roof insulation. The sheets have special grooves and are conveniently inserted into each other, thereby ensuring maximum tightness. The dimensions are as follows:

• length 600 mm;
• width 1200 mm;
• thickness 20-150 mm.

Foam sizes

The dimensions of this material are standard - the length and thickness can be as follows:

• 500*500 mm;
• 500*1000 mm;
• 1000*1000 mm;
• 2000*1000 mm.

The thickness of the foam varies in the range of 20-100 mm, i.e. from 2 to 10 cm. Depending on this, in practice the corresponding designations are used, for example:

• foam size 50 mm is polystyrene foam 50 (similar to size polystyrene foam 50);
• thickness 10 mm – polystyrene foam 10 (similar to polystyrene foam 10 mm thick);
• thickness 30 mm – foam 30.

There is also thin foam plastic with a thickness of only 10-15 mm. These are fragile sheets that have limited use. As a rule, they are used only in narrow places, for example, for finishing the ceiling, when it is necessary to maintain its height as much as possible without “eating up” excess space.

Thus, the dimensions of the products are standard - the main difference is the thickness. For example, there are polystyrene foam sizes of 50 mm, 100 mm and even 150 mm. It is clear that the larger it is, the better the thermal insulation properties. But it is better to choose the golden mean to facilitate the installation process - the optimal range is from 50 to 100 mm.
