ROCKWOOL RWA45 has been developed for thermal, acoustic and fire performance in a range of construction types. RWA45 is made up of high-quality resin bonded slabs in a variety of thicknesses and densities. Specialist facings are available to order to meet the specifications of unique projects. RWA45 is rated Euroclass A1 non-combustible, providing the highest level of fire performance. Using RWA45 in ceilings, walls and floors can help to compartmentalise rooms, reducing fire spread and damage. RWA45 insulation slabs achieve Lambda 0.035 W/mK and are available in seven standard thicknesses from 25-100mm, with a density of 45 kg/m3.
