FLOOR INSULATION

Polystyrene concrete panels, heat-insulating, dimensions.

600x400x60mm.

Polystyrene concrete panels, heat-insulating, are developed in compliance with the requirements of regulatory documents of the Republic of Uzbekistan, corresponding to the national standard O`zMSt338:2024 "Heat-insulating products made of polystyrene concrete. Technical conditions" and GOST 33929-2016 "Polystyrene concrete. Technical conditions".

Polystyrene concrete slabs, heat-insulating, are used for heat insulation of attic coverings and basement floors of buildings of various purposes with dry, normal and wet operating conditions.

They are manufactured within the medium density grade - D400, D450.

Polystyrene concrete slabs 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.
