With an underfelt collar (BFX) to create a watertight seal between the roof and the window, as well as an insulation collar (BDX) that removes cold bridges and prevents heat loss, this roof window features an EDJ recessed flashing. Compatible with tiles that have profiles up to 90mm thick, this flashing has a sleek finish that is streamlined, and it also ensures that the window fits 40mm deeper into the structure. This makes for minimal protrusion above the roofline. The blue line signals to where brackets should be positioned.

VELUX double glazing (70) provides premium features and high comfort. The UV filter prevents the fading of furnishings when subject to the sun's harmful UV rays, while the toughened glass equips the exterior pane with additional strength to withstand external environmental force. Alongside 35dB of sound insulation, the rain noise reduction keeps quiet atmospheres protected from outdoor noise and, if windows are broken, the safety lamination reduces the risk of scattered glass.
