Find out moreThis Celotex TB4030 is a multi-purpose polyisocyanurate (PIR) insulation board with excellent thermal performance. 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/mK, the thickness of the insulation required to meet the target uValue is reduced significantly, saving you space. The high-performance facing further improves thermal performance in sealed cavity air spaces, which brings up uValues 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 quick and 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. It has also been certified by the BBA (British Board of Agrément), so you can be sure it has been produced to the highest industry standards.
