Slab Insulation

Insulation slabs are an ideal solution for almost any roofing application, and are great when used within wall cavities and floors. Insulation slabs provide incredible sound and thermal insulation which helps to eliminate airborne sound as well as keeping homes, offices and other buildings warm throughout the year. Our selection of insulation slabs includes those manufactured by market leading brands such as Rockwool, Isover and Ecotherm and come in a range of densities and thickness.
