This glasswool cavity slab is designed for insulating external walls, supplied in a pack of five slabs with coverage of 2.73m². Each slab measures 1200mm by 455mm with an 85mm thickness, suitable for fitting between wall ties in typical cavity wall constructions.
On site, these slabs are positioned between masonry leaves to reduce heat transfer and increase energy efficiency. The interlocking design helps minimise air gaps, making installation straightforward for building projects requiring continuous cavity insulation.
