55mm Xtratherm Thin-R XT/CW is specifically designed to provide high levels of thermal insulation when building external walls and at the same time maintaining a residual cavity to prevent moisture penetration. 50mm residual cavity should be maintained to suit all exposure zones.

Xtratherm XT/CW offer certified thermal conductivity of 0.022W/mK which allows the boards to achieve exceptionally high standards of thermal performance.

Boards are manufactured with a Square Edge or Tongued and Grooved jointing (not readily available) system resulting in a more robust, continuous layer of cavity wall insulation that minimises the threat of thermal bridging through inaccurate installation. Please specify during checkout if Square Edge or Tongue and Groove jointing is required, if not specified Square Edge will be delivered.
