Unilin XtroLiner Cavity Wall Insulation PIR Board T&G 1200 x 450mm

XtroLiner is an innovative partial fill wall cavity insulation system incorporating robust facings and preformed corners. The XO/CW 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 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.
