Superior Performance PIR Insulation
XO/SK (T&G)
Applications: Roof / Pitched
XO/SK
XO/SK (T&G) is an engineered tongue and grooved external roof insulation system with robust facings which meets the passive U-value of 0.15 W/m2K.
Using XO/SK improves detailing, speeds up the installation process and provides a uniform plane to detail more effectively. Creating a warm roof reduces the normal amount of junctions prone to thermal bridging greatly improving the thermal performance of the roof.
U-Value calculations to EN ISO:6946
