Celotex GA4000 PIR Insulation For Floors, Walls & Roof Applications 50mm / 75mm / 80mm / 100mm

Designed for use throughout your building project, Celotex GA4000 is a versatile, high performance, rigid polyisocyanurate (PIR) insulation board that’s easy to handle and install.

As well as being CE-marked, Celotex GA4000 is certified by the British Board of Agrément for floors, framed walls and pitched roofs.

Manufactured in the UK, Celotex GA4000 provides reliable, long-term energy savings.

How does GA4000 perform?

The entire thickness range offers a low thermal conductivity (lambda value) of 0.022 W/mK, putting GA4000 among the best-performing widely-available insulation materials on the market.

In any of its intended applications, GA4000 can help to provide most of the thermal insulation performance - but the overall heat loss from a building element depends on all of the materials used and the way they’re installed.

Product benefits:

Celotex GA4000’s low emissivity aluminium foil facing can help achieve lower U-values when installed facing a clear air space within a construction.

GA4000 is a thermal insulation solution that can help to meet energy use and carbon dioxide emissions targets set by national building regulations.
