Thin-R Partial Fill Cavity Wall Plus XT/CWP (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/CWP (T&G) is the best solution when building traditional masonry walls to the highest thermal standards whilst maintaining a residual cavity, offering excellent protection from wind driven rain. The lower Lambda of 0.021 W/mK improves U-values and meets Zero Carbon standards, proving an excellent choice for passive and low energy builds
