Excellent thermal performance with a thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value.
Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value.
Celotex boards are light and rigid assisting with ease of transportation, handling and fitting.
Celotex GA4000 has been assessed by the BBA as fit for use in defined roof, wall and floor applications if installed, used and maintained as set out in the certificate. Please read the certification at insulation-UK.com/

Insulation for roof space
Just what I needed yo insulate my small loft space. Not difficult to use...a bit messy. Need eye and mouth protection!
Having never done anything like this it was a job fairly easily accomplished with basic tools.

Great insulation
Lovely insulation for my garage conversion floor, easy to cut and keeps the building control happy, just a shame I then had to bury it under a DPM and the. a concrete screed, never to be seen again! Good service for TP.
Celotex CW4000 is an easy to install polyisocyanurate (PIR) insulation board with excellent thermal performance, featuring a low emissivity foil facing. Available in thicknesses from 40mm to 100mm, it can be considered for use in partial fill cavity wall applications.
Warm Roof construction is a particularly effective way of insulating complex
roofs. Insulating above - or above and between - the roof timbers ensures
that the structure is kept at or near the internal environmental conditions,
reducing thermal stress and condensation risk.
Recticel Eurothane� GP is a high performance PIR insulation board for multiple applications, which is light weight, easy to cut, handle and install. Whether it's a pitched roof, framed wall or floor, Eurothane� GP is the ideal solution amongst contractors and installers
