Not so long ago, new thermal insulation materials have appeared on the construction market, which are made using extrusion. A special place in their list is foam, which is obtained by entering foaming reagents or light freons into polystyrene granules at high pressure and high temperatures. With this technology, material with a uniform cellular structure is obtained, which has a very high compression strength. In addition, its main advantages are low thermal conductivity and the lack of hygroscopicity, and temperature changes are not afraid of it.
The ecological purity and biological neutrality of this material ensures chemical inertia due to the materials used in the production of foams. In addition, it has excellent soundproofing qualities, does not rot and does not burn, and the foam is also protected from the appearance of the fungus and the propagation of bacteria.
Such material, depending on the type, is well suited for thermal insulation of floors and walls, ceilings and foundations, both in civil and industrial construction, during pipelines and the construction of pools. A more durable type of foam is applicable during the construction of roads and floors in warehouse and industrial premises.
