75mm Celotex GA4075 PIR Insulation Board 2400mm x 1200mm

What Is 75mm Celotex GA4075?

For top-tier thermal performance, trust in the 75mm Celotex GA4075 insulation board. These superior 2.4m x 1.2m PIR boards are equipped with low-emissivity foil facings, enhancing insulation, especially in sealed cavity air spaces.

Boasting a remarkable thermal conductivity of just 0.022 W/mK, these boards excel in preserving heat within a structure, all while adhering to building regulations and without encroaching on interior spaces.

The 75mm Celotex GA4075 is crafted with a rigid foam core and is responsibly produced using an ozone-friendly blowing agent with minimal global warming impact.

Perfectly suited for insulating floors, walls (be it partition or solid masonry), and roofs, the Celotex GA4075 doesn't just stop at thermal insulation. It also offers impressive resistance to water vapour and boasts a commendable compressive strength of 140kPa.

The GA4075 insulation board is just one of many popular thermal insulation solutions in the Celotex product range. It comes from the GA4000 product group, which includes 6 other thicknesses; 50mm (GA4050), 60mm (GA4060), 70mm(GA4070), 80mm (GA4080), 90mm (GA4090) and 100mm (GA4100).
