The 100mm Rockwool RWA45 Acoustic Sound Insulation Slab offers exceptional performance in thermal, acoustic, and fire insulation. Its high-density and non-directional fiber structure make it highly effective in reducing noise transmission between rooms and floors. It also provides excellent fire resistance, achieving an A1 non-combustible rating. Additionally, its low thermal conductivity helps protect the thermal envelope of the building, improving energy efficiency and reducing heating and cooling costs.
