Air tight flashing XDS-D

Maintaining complete airtightness around the flat roof window is essential for effective thermal insulation. Applying the XDS-D air-tight flashing allows for a tight connection between the vapour barrier membrane and the window, helps prevent warm, humid air from entering the insulation layer, reducing the risk of moisture build-up in the insulation, which leads to a significant decrease in its thermal insulation properties. The flashing is made of durable polyethylene membrane and is installed on the room side. The set includes adhesive tapes with high resistance to moisture and ageing, ensuring a durable connection.
