Unilin XtroLiner Cavity Wall Insulation PIR Board 1200 x 450mm

XO/CW is an innovative partial fill cavity wall insulation system incorporating robust facings, engineered jointing details, preformed 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 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.
