About PENOPLEX / Insulation of foundations / Construction in permafrost regions

When constructing buildings and structures in permafrost regions, the temperature field of foundations undergoes changes in comparison to tundra soils, primarily caused by the heat of buildings themselves. This forms thaw cups that lead to subsidence of buildings. The most economically viable and efficient remedy to this problem is using thermal insulating layers that limit the development of thaw cups.

Severe climatic conditions increase the requirements for insulating properties of protecting structures. The use of PENOPLEX^® insulation in frameworks of assembled and solid structures that include beamless floors made from flat slates, one-story piles, and three-layer two-story and one-story support panel of exterior walls, improves insulating properties of buildings and lowers their weight, which makes it easier to prepare pile foundations in permafrost soils. Thanks to PENOPLEX’s low thermal conductivity, it is possible to obtain more efficient protecting structures without changing the rigging for the manufacture of products from reinforced concrete.

The most common type of building is with ventilated subfloors. You can insulate first-story floors after installing the slate or use readymade floor boards with PENOPLEX^® insulation.

Calculation of the insulation layer is necessary. When using insulating materials within the poured mix body, the thermal insulating property, strength, and durability of insulation play an important role. PENOPLEX^® boards completely satisfy these requirements. The use of PENOPLEX^® in this situation will prevent the main buildings during construction and operation and increase the strength of foundation soil lowering its temperature by shifting the upper limit of permafrost soils up to the surface.

Using PENOPLEX^® boards will help lowering the height of an embankment, decreasing labor intensity and construction time, which is an important factor for constructing buildings and structures in permafrost regions.
