Celotex GA4000

High performance PIR insulation for floors, walls and roof applications.

What is Celotex GA4000?

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. Suitable applications include:

Ground floors - whether solid concrete, block and beam, or suspended timber joist, and including where underfloor heating is used.
Timber and steel framed walls - between and across the face of studs.
Pitched roofs - between and across the face of rafters.
Flat roofs - in ventilated cold roof constructions, installed from inside the building.
Other retrofit and refurbishment projects - lining existing timber and masonry structures to make them more thermally efficient.

As well as being CE-marked, Celotex GA4000 is certified by the British Board of Agrément for floors, framed walls and pitched roofs. Made at our original site in Hadleigh or our state-of-the-art facility in Eggborough (opened in 2018), you can be confident of it providing 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. Use the online and mobile U-value calculator to help you find the most efficient solution for each type of construction.

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. Check the frequently asked questions for common queries about positioning and installing products correctly, or contact our technical services team.

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