ROCKWOOL Sound Insulation Slabs are designed for use in internal and separating walls and floors to reduce noise from adjacent rooms or neighbouring properties. Ideal for use in home offices, bedrooms, and media and gaming rooms, the slabs are easy to fit around cables, pipes, sockets and services. Made from stone wool, the non-combustible slabs can withstand temperatures up to 1777°c, helping to reduce the risk of fire spread.
