Celotex GA4075 in 75mm is a low cost PIR insulation board that delivers excellent performance level across the board. It is a polyvalent product offering multiple thermal insulation options without compromising on its long term integrity or the environment. This is often a deciding factor for many contractors who are used to this range of Celotex and need to keep their construction projects on schedule. Simply put, Celotex GA4075 will help reduce the overall reliance on heating systems. With a thermal conductivity as low as 0.022 W/mK, it fits many applications whilst delivering high results

The 75mm Celotex insulation board requires no particular skills to install and can be easily cut and fitted without damaging the insulation. On top of that the foil facing acts as a vapour control layer when associated with an air cavity. The Celotex foil will reduce the risk of warm air making its way through the board, reaching the cold space. This is important to avoid condensation and dampness lingering on the structure and potentially damaging it. 

Made from a rigid foam core, with added blowing agents, the manufacturing process of Celotex GA4075 ensures that those agents are free of ozone depletion potential and low global warming potential.
