About this product
Celotex GA4100 PIR Insulation Board is a high-performance general-purpose choice for thermal insulation in floors, walls, and roofs. Part of the Celotex GA4000 range, it’s designed to deliver strong thermal efficiency with relatively slim build-ups. These boards come in a standard size of 2400 x 1200mm for a coverage of 2.88m² per board. They’re made with a polyisocyanurate (PIR) rigid foam core between aluminium foil facings, giving moisture resistance and durability. Celotex GA4100 PIR is a true multi-purpose insulation option, suitable for both new builds and refurbishment projects.
