XT/CW (T&G)

Partial Fill Cavity Wall

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.
