Superior Performance PIR Insulation

XO/SK (T&G)

Sarking Warm Roof Construction

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. This product has a Euroclass C Fire Classification.
