Where can I find your product sizes and dimensions? Can a skylight, roof window or sun tunnel leak? VELUX skylights, roof windows and sun tunnels use flashing kits that are specific to roof pitch and roofing material. Provided the proper VELUX Flashing is used and installed correctly, we will stand behind the product against leaks for a period not shorter than defined in our guarantees.
The unique construction of VELUX Skylights and flashings ensures safe drainage of rainwater coming from the roof above the window, providing complete weather tightness and preventing leakage. Because the roofing material covers both top and sides, VELUX flashings are largely unobtrusive.
VELUX undertake extensive testing to ensure that all products perform to the very highest standards. VELUX Roof Windows, Skylights and flashings are put through some of the worlds most severe artificial rain and wind tests.
What glazing types do you offer? VELUX offers comfort double glazing and high performance double glazing in the majority of its products. Visit our Glazing Options page for more information.
Who are the VELUX® dealers in my area? A list of VELUX dealers in your area can be found in our Where to Buy page.
Where can I find technical information and CAD Drawings on your products? Can I apply a film to the glass to decrease heat and light? VELUX does not recommend the addition of any store-bought film to the glass of our skylights. The addition of store-bought film or tint will void the warranty on the glass. However, our glass is manufactured with a Low-E coating and injected with Argon gas that make our skylights very energy efficient. In addition, we also offer several blinds that can be added to our skylights and roof windows to regulate light and heat.
Why is roof pitch important for skylight installations? Each of our flashing kits are engineered with specific pitch requirements. The roof pitch is important because it ensures that the roof has the proper slope to effectively drain water off of both the flashing and the skylight. The roof pitch and the roofing material used are both important in determining the type of flashing needed. Almost all VELUX products require a minimum pitch of 15º degrees with the exception of Curb Mounted Skylights (FCM) that can be installed on a 5º degree or greater pitch.
How do I measure my roof pitch? The most accurate method for measuring your roof pitch is with a pitch gauge placed on the roof itself. This gives an accurate degree measurement of your roof slope. (A pitch gauge can be purchased at local building supply stores.) The alternative is to measure the rise of your roof divided by the run of your roof.
Does VELUX make custom sized skylights? No, the VELUX product range comes on standard sizes ONLY as shown in the Price Guide.
What colors do your skylights come in? All current skylight units, including FCM, roof windows and sun tunnels, are umber-grey.
Can I convert my fixed skylight into a venting one? No. It would be necessary to replace the fixed skylight with a ventilating unit.
