Celotex GA4000 PIR Insulation Board
General Purpose PIR Insulation Board for Walls, Floors and Roofs
Celotex GA4000 is a high-performance rigid PIR insulation board designed for use across walls, floors and roof applications. It provides strong thermal performance in a slim board format, making it suitable for new build, refurbishment and general insulation upgrades.
Each board measures 2400mm x 1200mm and covers 2.88m². The GA4000 range is available in multiple thicknesses from 50mm to 100mm, giving you flexibility when working to a target U-value or available build-up depth.
Celotex GA4000 has a PIR insulation core with low-emissivity foil facings on both sides. This helps reduce heat loss and improve energy efficiency while keeping the boards lightweight, easy to cut and easy to install.
It can be used in a wide range of applications including pitched roofs, flat roofs, solid walls, timber frame walls, floors and general drylining insulation build-ups.
