TB4000

In conjunction with the other Celotex size ranges, the Celotex TB4000 works as a thermal break. The TB4000 range of PIR (polyisocyanurate) boards comes 4 different sizes, TB4012 is a 12mm insulation board, TB4025 is a 25mm board, the TB4030 is 30mm and the TB4040 is 40mm overall and these are all made from the same high performance insulation foam. As the TB4000 range suggests, the boards are designed to work with either the XR4000 or the GA4000 as an additional layer to reduce thermal breaks at the perimeter of flooring solutions or as an under board to the more substantial insulation board used in a roof construction. The TB4000 range of products comes with a foil vapour control layer to either face. As with other brands, Celotex like to let us know how made a product so the boards do have branding on the foil facings too. Luckily at Online Insulation, we are able to offer the best prices and availability, you can even choose a delivery date to suit you!
