Celotex TB4030 is a multi-purpose polyisocyanurate (PIR) insulation board with excellent thermal performance which is quick and easy to install. It features an innovative low emissivity foil facing and is perfect for use in floors, walls and roofs. Thanks to an outstanding thermal conductivity of 0.022W/m.K, the thickness of the insulation required to meet the target U-value is reduced significantly, saving you space. The high-performance facer further improves thermal performance in sealed cavity air spaces, which brings up U-values even higher.

What's more, this versatile, thin PIR insulation board, which is available in a size of 2400mm in length by 1200mm in width by 30mm in thickness, is easy to handle and install because it's so light and rigid. It comes with a BRE (Building Research Establishment) Green Guide Rating of A, ensuring it's sustainably sourced and environmentally friendly. TB4030 has also been certified by the BBA (British Board of Agrement), so you can be sure it has been produced to the highest industry standards.
