50mm Celotex GA4000 PIR insulation for floors-walls-roofs is a general purpose insulation board for floors, walls and roofs. It has long been at the heart of the Celotex product range providing the user with a range of thermal insulation solutions. With low emissivity foil facings, GA4000 is manufactured from rigid polyisocyanurate (PIR) using a blowing agent that has zero ozone depletion potential (zero ODP) and low global warming potential (GWP).How does 50mm Celotex GA4000 PIR insulation for floors-walls-roofs perform?
