Xtratherm Thin-R Cavity Fill PIR Insulation Board T&G 1200 x 450mm

Thin-R Partial Fill Cavity Wall (T&G) builds to a system thanks to its engineered tongue and grooved joint and pre-formed corners, ensuring insulation continuity and minimisation of thermal bridging. Cavity Wall (T&G) for use in traditional masonry walls, builds to the highest thermal standards whilst maintaining a residual cavity, offering protection from wind driven rain.
