Thermal insulation layer has a thickness of 100 ÷ 430 mm, depending on the requirements for thermal resistance. Polystyrene, semi-rigid stone wool, polyisocyanurate panels (PIR) are used for this layer. Walls with polystyrene thermal insulation are most often used in places with increased risk of moisture (basement, plinth elements). At the request of customers, expanded polystyrene can also be used in other wall constructions of the building. Stone wool with ventilation grooves is used for thermal insulation of walls above ground line. This wool is specially adapted to produce prefabricated reinforced concrete walls. Ventilation grooves are cut in stone wool on the façade side and the entire surface is covered with glass fabric. This forms a ventilated façade, which allows the removal of accumulated and accidental moisture from the wall structure during production or installation.
