Fakro XDS Air Tight Barrier

Fakro XDS Air Tight Barrier

The FAKRO XDS Air Tight Barrier is designed to help create a more airtight and thermally efficient installation around a FAKRO roof window. It forms a protective barrier between the warm, humid air inside the building and the insulation surrounding the roof window, helping to reduce the risk of moisture reaching the insulation material. Moisture on the surface of insulation can significantly reduce its thermal insulation performance. By helping prevent warm, humid air from reaching the insulation, the XDS Air Tight Barrier contributes to a more effective and properly sealed roof window installation.

Improved Airtightness Around the Roof Window

The XDS is installed internally around the roof window opening to create a continuous airtight barrier. The sheeting is designed to fit into a dedicated groove in the roof window frame, helping create a close and flush connection between the window and the surrounding roof sheeting. This design helps minimise unwanted air gaps around the window installation. By improving the airtightness of the roof window opening, the XDS can contribute to a more comfortable indoor environment and help protect the surrounding insulation from warm, humid air.

Quick and Straightforward Installation

The FAKRO XDS Air Tight Barrier is made from polythene and is designed for quick and easy installation. Its purpose-built design allows it to be fitted around the roof window without complicated preparation, helping installers create a properly sealed connection efficiently. The barrier is suitable for roof pitches between 15 and 90 degrees, making it adaptable to a wide range of roof designs. The correct XDS size should always be selected according to the dimensions of the roof window.

Designed to Protect Insulation

Maintaining effective insulation around a roof window is important for overall thermal performance. If warm and humid indoor air reaches the insulation and condensation forms, the insulation's ability to perform effectively can be reduced. The XDS Air Tight Barrier helps address this by creating an airtight layer between the internal environment and the insulation. When installed correctly, it helps keep the insulation protected and supports a more effective roof window installation.

Part of the FAKRO XDK Insulation System

The XDS Air Tight Barrier can be used as part of the FAKRO XDK insulation flashing system. The XDK set combines the XDP insulation set with the XDS air tight flashing to provide a coordinated solution for insulating and sealing around FAKRO roof windows. Using the components together helps make the installation process quicker and more straightforward while providing both insulation and airtightness around the roof window.
