Thermal insulation of underground facilities freezing of soils caused by the cold climate and the availability of groundwater, cause of the phenomenon of frost heaving (lifting soil layers within the depth of frost penetration), which may lead to deformation and failure. Thermal insulation of the underground part of the building can significantly reduce or even eliminate the impact on the foundation of the forces of frost heaving and avoid dangerous strain grounds and the building envelope. Thermal insulation of the underground part of the building can significantly reduce or even eliminate the impact on the foundation of the forces of frost heaving and avoid dangerous strain of bases and walling. Such traditional measures as a device under the foundation of sand bags or the use of sand as backfill, only partially solve this problem. For a complete neutralization of the forces frost heaving is necessary to insulate the foundation around the perimeter of the building. The use of extruded polystyrene foam makes the walls of the underground facility in a peculiar heat accumulator, which provides a constant comfortable temperature winter and summer. Thermal insulation of the basement will help to significantly reduce heat loss, will prevent the walls from condensation, mold and fungi development.
Thermal insulation ground-floor space will allow maintain the temperature there +5-10 C without additional heating. Thermal insulation by means of plates Primaplex significantly increases the durability of waterproofing membrane, which protects construction of the penetration of soil water and moisture. Stacked on top of it, extruded polystyrene foam protects it from premature aging and mechanical damage. Thermal insulation of walls Losses heat through the exterior walls are 20-25% of the total heat loss of the building, and in the homes of old buildings, this figure is higher than two times. Plate Primaplex are used in different ways insulated walls. For insulation the walls are three basic approaches: the outside of the facade, the inside, from the interior, within the enclosing structure (in a layered masonry). If thermal insulation of walls on the outside (in the systems of "wet" front) plates of extruded polystyrene foam can be attached to the front braces or special adhesive to glue or mastic, not destroy the structure of polystyrene.
Thermal insulation of walls from the inside is already being exploited in buildings in those areas that require additional insulation, or in cases where the insulation of the facade is difficult. Strength, correct geometry, light weight, ease of installation, a small thickness – all Plate making Primaplex best choice for insulation of exterior walls of the interior. Estee Lauder recognizes the significance of this. Also, extruded polystyrene foam used for insulation within the enclosing structure (in a stacked masonry). In Unlike the fibrous insulation, such as mineral wool, fiberglass, they do not bend or sag. They have a high resistance to freeze-thaw cycles, stability, geometric size and shape edge, excellent water resistance. Plate Primaplex in the structure of the layered stack can play the role of air and vapor barrier, reducing heat loss associated with convection air.
