Skylights

VELUX Skylights

All VELUX windows are manufactured at their own factories. In the US, the wood used for our skylights comes from controlled sources as close to our factory as possible. Overall, 99.5% of the wood used for VELUX windows is sourced from certified, sustainable forests, and all wood cut-offs and chips from our production sites are used for recycling or heating purposes.

VELUX skylights are built at our manufacturing sites where we run extended internal audits to monitor compliance with all critical safety standards. They are then packaged with everything a roofer, builder, or general contractor needs to install the skylights and flashing kits. And when it comes to installation, VELUX has made it as simple as possible to do by eliminating mistakes that can lead to leaks.

Both VELUX deck-mounted and curb-mounted skylights include three layers of protection from water leaks. Each type of skylight has a unique first layer to protect against leaks: the deck-mounted skylights have a deck seal while curb-mounted models have a pre-attached skylight gasket.

In every VELUX skylight box is an adhesive all-weather underlayment, often called a peel-and-stick underlayment, which is similar to thick pieces of tape in strips 25 feet long by 9 inches wide. The underlayment is installed up the side of the skylights and serves as the second line of defense against rain.

VELUX designed step flashing exclusively for our skylights as a final line of defense against rain. Metal flashing pieces alternate with the roofing material starting at the bottom of the skylight and working up to the top. Rain flowing down the roof is sluiced over the layered shingles and away from the skylight.
