Celotex PIR GA4070 - 2400 x 1200 x 70mm
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:
Board Size: 2400 x 1200 x 70mm
Thermal conductivity: 0.022 W/mk - BS EN 12667.
Compressive strength: ≥140kPa - BS EN 826.
Water vapour resistance: >150MNs/g - BS EN 12086: Method B.
Spread of flame: Class 1 - BS 476-7.
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.
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 our online and mobile U-value calculators to help you find the most efficient solution for each type of construction.
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 our 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.
Facer: Low emissivity composite aluminium foil
Manufactured using a blowing agent with zero ozone depletion potential (ODP) and low global warming potential (GWP).
