Xtratherm XT/CW Cavity Wall Insulation Board T&G is a polyisocyanurate (PIR) based insulation solution for partial fill wall applications. It performs very well thermally, with a lamba value of just 0.022 W/mK, which means it minimises the passage of within the air space. One thing that sets these Xtratherm cavity boards apart from other manufacturers is that they have T&G edges which allows the boards to slot together, thus minimising thermal bridging. As a partial fill solution, they maintain a residual cavity which protects against wind driven rain. Sized at 1200mm x 450mm, the boards fit conveniently between traditional brick ties. They are suitable for brick and block cavity walls and can be used in new builds and extensions alike. Xtratherm cavity wall boards are sold in packs wrapped in plastic.If you are looking for similar products to Xtratherm 100mm PIR, Celotex sell 100mm PIR boards called GA4100.
