Applications:Wall / Partial

XT/CW (T&G)

Thin-R Partial Fill Cavity Wall XT/CW (T&G) builds to a system thanks to it’s engineered tongue and grooved joints and pre-formed corners, ensuring insulation continuity and minimisation of thermal bridging.

XT/CW (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.
