The FAKRO XDS Air-Tight Flashing is designed to provide a secure internal seal around roof windows, forming a vital barrier against warm, moist air from inside the building. This prevents condensation from reaching the insulation, helping to maintain its full thermal performance and extend the lifespan of your roof window installation.

Made from high-quality polythene, the XDS flashing is quick and simple to install. It fits neatly into a dedicated groove in the window frame, ensuring a flush, airtight connection between the window and the surrounding sheeting.

Ideal for use on roof pitches between 15° and 90°, the XDS is an essential component for ensuring energy efficiency and long-term protection against damp-related issues.

Key Features:

  • Creates an internal airtight seal to prevent condensation and damp.
  • Preserves insulation performance by keeping it dry.
  • Quick and easy installation – fits directly into the window frame groove.
  • Suitable for roof pitches from 15° to 90°.
  • Made from durable polythene.

Use as part of the FAKRO XDK Insulation Kit or as a standalone product for airtight window installations. Perfect for both new builds and retrofit projects where airtightness matters.

Consider choosing the XDK Insulating Set, which combines the XDS Airtight Flashing and the XDP Insulating Set in one convenient package.

FAQ's

Measuring Guide

All measurements are displayed width x length and it is important that you leave a 10mm gap all the way around the window when fitting, this is for things like flashing and insulation.

For example, if you had a 78x98cm window, the opening in the roof would need to be 80x100cm. We would recommend contacting a qualified builder or window fitter to measure your space before purchasing.
