This glass mineral wool slab is designed for insulating external masonry cavity walls. Each slab measures 1200mm by 455mm with a thickness of 125mm, making them suitable for installation between standard wall tie spacings. The dense, yet flexible structure aids in fitting securely within wall cavities to limit heat transfer.
Supplied in an 8-pack that covers 4.37m² in total, this product is typically used on site to provide thermal insulation in new or refurbished buildings. Its physical properties offer a practical solution where reliable, consistent coverage is required during cavity wall construction.
