Rockwool Cavity Wallbatts 1200mm x 455mm

Rockwool Cavity Batts offer an excellent insulation solution for new builds and extensions, whether residential or commercial. Designed to meet the demands of modern construction, these non-combustible, fire-resistant batts feature water-repellent additives for enhanced durability. The mineral wool insulation effectively prevents moisture penetration, ensuring long-lasting thermal performance. Lightweight and easy to handle, the Full Fill Cavity Batts are straightforward to install, fitting snugly against brick and blockwork while accommodating imperfections in the cavity wall. As a rigid full-fill insulation option, they provide reliable resistance to fire spread both within and between cavities, forming a protective barrier when securely placed between masonry leaves at the junction of insulated and uninsulated wall cavities.
