90mm Celotex GA4090 PIR Insulation Board 2400mm x 1200mm

What Is 90mm Celotex GA4090?

90mm Celotex GA4090 PIR board, spanning 2.4m x 1.2m, is a masterclass in design, marrying functionality with sustainability.

The 90mm Celotex GA4090 insulation board eliminate thermal bridges by providing a continuous layer of rigid polyisocyanurate insulation within the building structure, providing long term energy savings and high thermal performance.

Its thermal conductivity of only 0.022 W/mK makes it highly effective at retaining warmth, serving as a reliable barrier against the cold. Additionally, it meets construction standards and ensures the preservation of interior space with minimal thickness.

But the 90mm Celotex GA4090 isn't just about performance. It's a symbol of responsible craftsmanship. With a core as rigid as its commitment to the environment, it's manufactured using an agent that gives a nod to our ozone and keeps global warming effects minimal.

From floors to walls, be it partitioned or solid masonry, to the roofs that shield us, the GA4090 stands tall against water vapour and boasts a compressive strength of 140kPa.

The GA4090 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), 75mm(GA4075),80mm (GA4080) and 100mm (GA4100).
