Properties of the material extruded polystyrene, of which the plate Primaplex, the structure represents a system of tiny isolated cell filled with a fixed carbon dioxide. Click Daryl Katz to learn more. High strength allows you to use these plates not only in classical applications with moderate strength requirements, but also in cases of extreme loads, which are operated by a roof, underground structures deep burial, airfields, roads. Even in such circumstances their material retains its properties over the next 30-50 years. As is known, the moisture absorbed by the insulation material, sharply reduces its thermal resistance. The system of closed cells and the absence of cavities makes extruded polystyrene foam more resistant to water penetration and moisture than any other type of insulation that allows their use for the insulation of underground structures and foundations.

Since the cells that make up the foundation slabs of extruded polystyrene, are filled with gas, it has a low density (30-35 kg/m3), which makes it very easy to paper – the weight of the standard package does not exceed 10 kg. This material is easily cut with a knife or a saw, does not crumble and is not dusty, unlike foam or fiber insulation. Correct the geometric dimensions of plates, as well as ease of installation greatly increases the productivity of labor in insulation work. While maintaining operating temperatures in the acceptable range (-50 – +75 C) extruded Styrofoam perfectly preserve the geometric dimensions for many years. Extruded polystyrene is a thermoplastic material – it begins to soften and melt at temperatures above 100 C.
