ROCKWOOL RW4 has been developed for thermal, acoustic and fire performance in a range of construction types. RW4 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.
The ROCKWOOL slabs can be applied to an array of general building applications for acoustic and thermal insulation of partition walls,
ceilings, floors and roofs. The multi-use solution is well suited for easy application throughout constructions. RW4 is rated Euroclass A1 non-combustible, providing the highest level of fire performance. Using RW4 in ceilings, walls and floors can help to compartmentalise rooms, reducing fire spread and damage. RW4 insulation slabs achieve Lambda 0.034 W/mK and are available in three standard thicknesses from 50-100mm, with a density of 80 kg/m3.
