This glass mineral wool cavity slab pack is designed for insulating external walls in new builds and extensions. Each slab measures 1200mm by 455mm with a thickness of 65mm, providing a practical fit between standard wall ties and cavity spaces for straightforward installation.
Supplied in packs covering 5.46m², the slabs are commonly installed to help limit heat loss through masonry cavity walls. Their flexible format allows for close butting, reducing the chance of gaps and maintaining insulation continuity within the wall structure.
