Unilin Thin-R Cavity Wall T&G Insulation PIR Board 1200 x 450mm

Unilin / Xtratherm Thin-R Cavity Wall XT/CW (T&G) insulation builds to a system, thanks to its engineered tongue and grooved joints and pre-formed corners. This ensures insulation continuity and minimisation of thermal bridging. XT/CW (T&G) is made for traditional masonry walls, which can be used to build to the highest thermal standards whilst maintaining a residual cavity, offering protection from wind driven rain.
