Rockwool Cavity Wallbatts 1200mm x 455mm x 75mm Pack of 9 (4.95m2)

Rockwool Cavity Batts make a great solution for new builds or extensions – from homes to commercial. The non-combustible, fire resistant solution has been developed for the requirements of new build construction and contains water repellent additives. The mineral wool insulation Full Fill Cavity Batts critically prevent moisture transmission and maintain insulation for the long term. The Full Fill Cavity Batts are lightweight and easy to handle, making installation simple and providing a close fit against brick and blockwork, whilst also adapting to imperfections in the cavity wall. As a rigid full-fill insulation solution, the product ensures a resistance to fire spread between and within cavities. It acts as a barrier when tightly fitted between masonry leaves where an insulated wall connects with an uninsulated wall cavity.
