This semi-rigid glass mineral wool slab is designed for insulating masonry cavity walls in both new build and refurbishment projects. Each slab measures 1200 x 455 x 50mm, fitting standard wall tie spacings to streamline installation and minimise gaps.
Supplied in packs covering 6.55m², the slab is easy to cut and friction-fit between wall ties, with no retaining discs required. Its water-repellent properties help reduce the risk of moisture transfer across cavities, supporting reliable insulation and helping protect interior finishes on site.
