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.
Celotex TB4000 achieves a BRE Green Guide Rating of A, which can assist in demonstrating environmental performance in your BREEAM assessments . Please visit the Celotex page at GreenBookLive.com for further details.

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
Is made of shaped polyethylene foams glued to aluminium coated polyethylene foils. The unique honeycomb structure composes of a large number of low emissivity cavities that ensure high thermal performance. The reflective insulation product has a heat capacity of 2300JK/kgK. The panels can be used on timber frame, masonry walls, pitched roof, ceilings, floors & suspended timber floors. The lightweight Hybris panels have a tensile strength greater than 45kPa before and after ageing in both longitudinal and transversal directions. The tensile strength is tested to EN 1608 and the tearing and nail shank resistance to EN 12310- 1 part 1.
