Rigid polyisocyanurate insulation for partial fill cavity walls.
XO/CW T&G is an innovative partial fill wall insulation system incorporating robust facings, engineered jointing details, performed corners and a certified lambda of 0.021 W/mK.
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.
