Celotex Thermal Insulation Board

Suitable for:

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.

Specification:

We stock the GA4000 in a range of thicknesses:

Type Size Thickness
Celotex GA 4000 2.4m X 1.2m 50mm
Celotex GA 4000 2.4m X 1.2m 60mm
Celotex GA 4000 2.4m X 1.2m 70mm
Celotex GA 4000 2.4m X 1.2m 80mm
Celotex GA 4000 2.4m X 1.2m 90mm
Celotex GA 4000 2.4m X 1.2m 100mm

 

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.

Description

Celotex GA4000’s low emissivity aluminium foil facing can help achieve lower U-values when installed facing a clear air space within a construction.  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. As it is manufactured using a blowing agent with zero ozone depletion potential (ODP) and low global warming potential (GWP).

 

1With regard to floors, the BBA certification assessed thermal performance, condensation risk, floor loading and durability. With regard to timber frame dwellings up to 18m in height, the BBA certification assessed thermal performance, condensation risk, water resistance and durability. With regard to pitched roofs, the BBA certification assessed thermal performance, condensation risk and durability.

I just wanted to say a huge thank you to you and your team for all the extra help you have given me in dealing with my rather sensitive issue of noise transmission to my downstairs neighbour. It has been invaluable. In recognition, I have made a £50 donation to the charity: Action on Hearing Loss.
