This pack of glass mineral wool slabs is designed for insulating external masonry cavity walls. Each slab measures 1200 x 455 x 100mm and the pack covers a total area of 6.55m², making it suitable for most standard wall cavity applications.
On site, the semi-rigid slabs are sized to fit standard vertical wall tie spacings, allowing straightforward installation between wall leaves. The product is typically installed during construction to improve thermal efficiency and help resist moisture in cavity walls.
