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.

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.
