Review: The guarantee that Velux offers on their products and the service that they give in addressing any warranty issues, is one of the main reasons we recommend their products so much. We end up having very few warranty issues on the skylights and their flashing systems, but if we do, Velux works with us and our client to remedy the situation very quickly.
The 20 year guarantee on the glass for seal failure is incredible. Over the past 26 years, we have only had 2 units that have suffered seal failure. Considering we have installed over 15,000 Velux skylights, that is an incredible record.

Review: When we are installing a sun tunnel that will not be on a south facing roofline we like to use the pitched sun tunnel. The raised framework of this sun tunnel, allows it to have better exposure to the sun when it's on an east/north/west facing roofline (it's always facing straight up to the sky). Although the look is a little more prominent on the roofline, the extra amount of light it generates, is well worth it. We also really like that the entire exterior flashing is moulded from one piece of aluminum, so there are no seams in the flashing of this unit. Our clients are always amazed at the amount of light that comes from these small tubular skylights. It's the best value in sunshine that we can offer our clients!
