XO/SK (T&G)

XtroLiner Sarking (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 this product 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

Benefits

Specification Clause

The pitched roof Sarking insulation shall be XtroLiner XO/SK manufactured to EN 13165 by Unilin Insulation, comprising of a rigid modified Polyisocyanurate (PIR) core with textured robust foil facings and engineered T&G jointing. The XtroLiner XO/SK_ _ mm with a Lambda value of 0.021 W/mK to achieve a U-Value of _ _ _W/m2 K for the roof element. To be installed in accordance with instructions issued by Unilin Insulation.

An Environmental Product Declaration (EPD), certified by IGBC is available for this product. Please contact technical support for further details.

Refer to NBS clause P10 15, P10 140, P10 50, K11 695, K11 55. Uniclass Pr 25 71 63 66.

Resistance ‘R’ Values

The resistance value of any thickness of Unilin insulation can be ascertained by simply dividing the thickness of the material (in metres) by its Lambda value, for example: Lambda 0.021 W/mK and thickness 125mm -> 0.125/ 0.021 -> R-Value = 5.95. In accordance with EN 13165, R-Values should be rounded down to the nearest 0.05 (m2K/W).

1. The XtroLiner Sarking tongue and groove 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 roof.

2. Detailing with breather membranes and vapour control membranes can be more accurately achieved with insulation in a single plane.
