Knauf stone wool K2 100 kg / m³ (50 mm) - high quality, fire-resistant, heating and sound insulation material. Volcanic origin provides long-term exploitation and environmental security by preparing natural raw materials. Thanks to the density of 100 kg / m, it is higher than heating and voice absorption ability. The thickness of 50 mm thicks the optimal insulation layer, minimizes energy losses and provides strength to structures. In industry, commercial and residential facilities, walls, roofs, flooring and the insulation of ceilings are effectively used.
