• Rock wool• Glass wool

Divided according to material density to: – very light products (density < 50 kg/m3); – light (density from 50 kg/m3 to 200 kg/m3 ); – heavy (density From 200 kg/m3 to 400 kg/m3 ).

According to compressibility (material affected by 2 kPa load) into: – Soft (compresses more than 30 %); – half rigid (compresses from 6 to 30 %); – Rigid (compresses not more than 6 %).

according to usage for constructions into: – general purpose: • not Withstanding loads (light carcass type) • Withstanding loads (molded concrete Floors) in constructions – outer walls; – flat roofs.

Raw material type is chosen depending on resistance to temperature (basalt wool from 1000ºC, dolomite wool 650ºC, glass 550ºC), fiber thickness, Deformity

General mineral wool’s properties • dimensions (thickness), • density, • Heat conductivity coefficient, • compressibility, • concentrated load, • air Permeability coefficient, • flammability, • eco-friendliness, harmlessness.
