80mm Celotex PIR Insulation GA4080 is a general-purpose insulation board that can be used across a wide range of projects. Possible examples include roof insulation for flat or pitched roofs, cavity wall insulation, and floor insulation. The boards have a rigid polyisocyanurate (PIR) core with foil facings on both sides. They come in standard 2400 x 1200mm sheets for a coverage of 2.88m² per board. With a thermal conductivity of ~0.022 W/mK, they provide very high insulation performance, reducing heat loss, improving energy efficiency and lowering heating costs on finished builds.
