Flashings

VELUX flashing: do I really need it?

Flashings are essential for the correct installation of roof windows. Precisely designed flashing details ensure a durable and neat fit with the roofing material used. The purpose of flashing is to ensure good drainage away from the window and to provide protection from the elements.
VELUX offers a range of flashings designed for different roofing materials and provide two options for installation height (standard and recessed).

VELUX flashing: standard or recessed installation?

Recessed installations offer a more sleek, streamlined appearance, sitting 40mm deeper in the roof structure. Recessed installations also offer greater energy efficiency, and when installed with the appropriate VELUX insulation collar actually offer a lower certified u-value, saving energy and providing architects with greater design flexibility.
