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 XR4000 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/

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.
The Celotex PL4000 is a thermal laminate board, offering great insulation values. If you're insulating a small room or a garage where space is minimal then the Celotex PL4000 thermal laminate is an ideal solution.
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.
Celotex PL4065 Insulation Plasterboard offers a completely unique thermal insulation board bonded with a 12.5mm Plasterboard aimed at reducing overall installation time. Ideal for pitched roofs, flat roofs and walls this product offers both direct bonding (dot and dab) and mechanically fixed installation options. The tapered edge offers complete installation flexibility while maintaining its reliable long-term energy saving characteristics. As with all Celotex products they utilise agents that have Zero Ozone depletion potential (ODP) and Zero Global Warming Potential (GWP).
