The TB4040 is a part of the TB4000 range by Celotex. This is a high performance (PIR) insulation board. The board itself is made from rigid polyisocyanurate and is designed to reduce localised heat losses as well as address thermal bridging. The TB4040 range is highly adaptable, which means that is can be used throughout a building project. Our 40mm Celotex can be easily cut and shape for use. This multi purpose board was developed as a simple solution to overcome localised thermal bridges. It boasts blowing agents that have an ozone depletion potential of zero (zero ODP). In addition to this, the Celotex 40mm insulation board has low global warming potential (GWP)
40mm Celotex insulation board is well suited to walls, floors and roof systems. It was originally designed to eliminate thermal bridges, however, specific applications include perimeter upstand insulation in ground floors and lining door and window reveals in retrofit projects. The polyisocyanurate rigid foam insulation core boasts a thermal conductivity of 0.022 W/mk. In addition to this, it also features low emissivity foil on each side that is made from aluminium. This product is formed as a part of the TB4000 range and therefore is A+ rated. 40mm Celotex is manufactured in accordance with BS EN ISO 9001:2000.
These insulation boards can be used for a variety of applications including flat roofs, pitched roofs, masonry walls as well as timber-framed and steel framed systems.
Celotex has the broadest selection of insulation board widths, which range from 12mm up to 200mm to cater for almost all building projects.
