NyRock Cavity Slab 032 is a stone wool insulation product designed for thermal insulation in masonry cavity walls, with a thermal conductivity of 0.032 W/mK. The lightweight slabs are suitable for new builds, renovations, and extensions, and are easy to handle and install, providing an accurate fit against the blockwork. Manufactured using patented technology, NyRock Cavity Slab 032 has a more efficient fiber structure that increases the density of air pockets trapped within each slab. As a result, it provides an improved thermal performance when compared to typical stone wool products.
