XO/CW Tongue & Groove is an innovative partial fill wall cavity insulation system incorporating robust facings, engineered jointing details, preformed corners and a certified lambda of 0.021 W/mK. The XO/CW Tongue & Groove jointing offers a practical on-site solution that results in a more robust continuous layer of insulation, minimising the threat of thermal bridging and improving the overall U-value of the wall.
This lower lambda improves U-Values and meets Zero Carbon standards, proving an excellent choice for passive and low energy builds. XO/CW (T&G) partial fill can achieve a passive U-Value of 0.15 W/m2K in a traditional cavity wall. Using XO/CW allows the residual cavity to be maintained, offering excellent protection against wind driven rain. This product has a Euroclass C Fire Classification.
