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 TB4000 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/BBA for full details and restrictions.

Excellent PIR board. Easy to work with (easier than 50mm or 100mm) and performs well above the 25mm thickness you'd expect. Cheaper than Kingspan too!

Celotex used to provide heat barrier in a artificial fireplace
Celotex CW4000 PIR cavity wall insulation board measures 1.2m in length, 45cm in width, and has a thickness of 8.5cm, providing a total coverage area of 0.54 m². Celotex CW4000 is an easy-to-install polyisocyanurate (PIR) insulation board with excellent thermal performance, featuring a low-emissivity foil facing.
Xtratherm Pitched Roof Insulation Board 2.4 m in length, 1.2 mm in width, and 12 cm thick providing a total coverage area of 8.64 m2, 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 PL4025 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).
Recticel Eurothane GP is a high performance PIR insulation board 2.4 m in length, 1.2 m in width, and 2.5 cm thick, providing a total coverage area of 2.88 m2.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
