Polystyrene concrete blocks, regular, self-supporting D-500.
Regular polystyrene concrete blocks are developed in compliance with the requirements of regulatory documents of the Republic of Uzbekistan, corresponding to the national standard O`zMSt338:2024 "Thermal insulation products made of polystyrene concrete. Technical conditions" and GOST 33929-2016 "Polystyrene concrete. Technical conditions".
Regular polystyrene concrete blocks are used for the construction of non-load-bearing external walls as frame filling, self-supporting walls when constructing the external enclosure of a multi-story building frame, and load-bearing complex walls for single-story buildings.
Regular polystyrene concrete blocks are non-toxic, do not pose a danger during storage, production and transportation. They also belong to the flame-retardant materials of flammability group A1 and flammability group B1.
