This product consists of water-repellent glass mineral wool slabs, sized 1200 x 455 x 125mm, intended specifically for thermal insulation in external full-fill masonry cavity walls. It is supplied as a pack of four slabs, covering 2.18m2, and is designed for typical application in new builds or refurbishment projects where thermal performance is key.
On site, the slabs’ lightweight, compression-packed format supports easy handling and rapid installation between masonry wall leaves. The material provides a close fit within standard cavities and resists water ingress, assisting with effective insulation and maintaining cavity integrity during construction.
