Product Information

Celotex PIR TB4030 - Half Sheet -1200 x 1200 x 30mm
The thinnest product manufactured by Celotex, TB4000 is a high performance, rigid polyisocyanurate (PIR) insulation board specifically designed to address thermal bridging and reduce localised heat losses.
Board Size: - Half Sheet -1200 x 1200 x 30mm
Board Coverage: 1.44m2.
rValue: 1.35m2K/W.
Weight: 0.98kg/m2.
Thermal conductivity: 0.022 W/mk - BS EN 12667.
Compressive strength: ≥120kPa - BS EN 826.
Water vapour resistance: >150MNs/g - BS EN 12086: Method B.
Spread of flame: Class 1 - BS 476-7.
It can be used throughout a building project to help maintain continuity of the insulation envelope, and is suited to floor, wall and roof systems. Specific applications include perimeter upstand insulation in ground floors and lining door and window reveals in retrofit projects.
As well as being CE-marked, Celotex TB4000 is certified by the British Board of Agrément for floors, framed walls and pitched roofs. 
How does TB4000 perform? The entire thickness range offers a low thermal conductivity (lambda value) of 0.022 W/mK, putting TB4000 among the best-performing widely-available insulation materials on the market.
TB4000 will contribute to the thermal performance of any element in which it is used - 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.
Product benefits Celotex TB4000’s low emissivity aluminium foil facing can help achieve lower U-values when installed facing a clear air space within a construction.
