What is a "Penoplex Foundation"

In the building materials market,distribution received "Penoplex Foundation." What kind of material is it and how is it more attractive than other heat-insulating compounds? Let's try to understand this question.

general characteristics

Extruded polystyrene foam for thermal insulation"Penoplex Foundation" is specially designed for reliable protection of foundations. If you apply the insulation of the foundation "Penoplex" in the cottage, then the heat dissipation into the atmosphere by the construction of the whole building will be reduced by 20 percent.

This material is successfully used for buildings onAreas characterized by severe frost and high humidity. The thickness of the plate "Penoplex" is available with values ​​from 20 to 100 mm. "Penoplex Foundation" is made "with a quarter" - the chosen configuration of the edges of the plates allows to avoid the formation of cold bridges. This production technology ensures long-term thermal insulation of surfaces.

Extruded polystyrene foam "Penoplex"successfully resists prolonged contact with water, does not interact with soil alkalis and acids when it comes into direct contact with the soil. This material is not subject to bioavailability, does not change its physical and chemical properties when exposed to groundwater.

"Penoplex Foundation": characteristics

• The density is 29.0-33.0 kg / m³.
• The ultimate strength in the case of static bending is not less than 0.4 MPa.
• Absorption of water in 24 hours - no more than 0.4 percent (by volume).
• Water absorption for 28 days is 0.5% by volume.
• Resistance to fire - group G4 (according to F3-123).
• The coefficient of thermal conductivity (at 25 ° C) is 0.03 W / (m × ° K).
• Standard dimensions, mm: width / length - 600х1200.
• Thickness, mm: 7 gradations from 20 to 100.
• Range of operation (temperature) - from -50 to +75 ° С.

Comparison with other materials

On the thermal insulation properties of the penoplex sheetthickness of 2 cm corresponds to a thickness of 3 cm of the foam layer, 3.8 cm of mineral wool, 25 cm of wood, 27 cm of foam concrete, and 37 cm of brickwork. Thus, it is understandable why the use of "Penoplex" for the thermal insulation of foundations is preferable to the use of other materials.

Areas of use

"Penoplex Foundation" finds application in the following areas:

• as a middle layer in three-layer constructions from foundation blocks;
• as a non-removable formwork for pouring the substrate;
• for warming the bottom of the slabs of the undamaged buildings and the lower surface of shallow foundations;
• for insulation and moisture protection of the basement of buildings;
• for insulation of vertical surfaces of foundations;
• for warming of blind area in private houses with insufficient degree of insulation of the foundation;
• for the warming of the cellars of buildings.

Technology of thermal insulation of horizontal surfaces

For this application, and it deals with casesthermal insulation of the lower surface of the slabs and soles of tape (including shallow) foundations, use plates "Penoplex Foundation" 50 mm (or 100 mm).

1. Remove the top soil layer of the markedsite to the depth in accordance with the construction project. To achieve evenness of the bottom, the bottom 20-30 cm is selected manually. The whole area is covered with a layer of sand and it is rammed.
2. Do the temporary formwork and pour it without reinforcing a thin layer of concrete, getting a concrete foundation.
3. After hardening, the latter is laid on it without gaps of the plate "Penoplex Foundation", then a waterproofing layer made of a thick polyethylene film is applied, gluing strip joints with adhesive tape.
4. Manufacture is made in the usual way (with reinforcement) of the slab foundation, after solidification of which the formwork is removed and the "Penoplex" plates are insulated by its side walls.

Technology of thermal insulation of vertical surfaces

It is used on the foundations.And also for additional insulation of the constructed buildings. In the latter case, the foundation is first dug out to the depth of its bedding or to the depth of freezing of the soil.

1. The foundation is cleaned of dirt and dust,level its surface with cement mortar. Waterproofing with polymeric or bitumen mastic on a water basis (without solvents - they destroy "Penoplex").
2. Dilute, mix and leave for maturing glue for expanded polystyrene. With the help of a level, the lower boundary of the stacking of plates is marked on the foundation.
3. With the help of glue, applied on the plate "Penoplex"blots in several places, set it on the foundation, pressing it for a few seconds. The following plates are fastened, combining the mounting grooves. The installation of several layers is carried out with displacement both vertically and horizontally in the same way.
4. For the underground part of the foundation, no morestrong fastening of "Penoplex" - after filling it will be pressed firmly by the soil. To insulate the aerial parts of the cap "Penoplex" it is necessary additionally to fix with the help of so-called dowel-nails with a wide plastic perforated cap, which allows to tightly press the heater to the wall. To do this, through the plates drill holes in the foundation material to a depth of 30-40 mm. The length of the drill is chosen based on the thickness of the insulation.
5. The decorative finish of the socle is straightover the heat insulation plates. After reinforcing their mesh and processing the primer. In this case, you can use decorative plaster or tiling (stone) with a tile adhesive.

Warming of the footbridge

Thermal insulation of the ground is used to reduce the estimated depth of foundation and reduce the cost of its erection.

1. For this, after the drainage of the foundation and its vertical external thermal insulation is completed, it is covered (using sand and gravel) 10-15 cm below the ground level.
2. Perform formwork from boards in 1 meter from walls in height approximately 25 see.
3. The base of the blind area is leveled, rammed and stacked with "Penoplex" plates.
4. Close the "Penoplex" with a plastic film with a slight elevation on the plinth, then fill the formwork with concrete, leveling it with a slight slope from the walls of the building.
5. After solidifying the concrete, remove the formwork and decorate the blind with paving slab or stone.

Thus, we have clarified the main points concerning the properties and application of the construction material "Penoplex Foundation." Its price is about 4200 rubles / m³. This is quite expensive, but the material justifies its price by high performance.
