About This Product

VELUX VSS solar powered "Fresh Air" skylights light up your home and provides ventilation using only the power of the sun. It features a solar panel that captures any available daylight and uses it to recharge a highly efficient battery powered operator and control system. The solar panel does not have to be exposed to direct sunlight to function, so it will work on cloudy days and with indirect light.

      Q:#1. I intend to install a 21x54 venting skylight on my metal roof. is the metal roof deck mounted flashing good? #2. Iminstalling 2 14" vellum light tubes with the built in flashing on the same metal roof. should I build a curb?

      Answer This Question

      A:  If you have a standing seam metal roof, the flashing kit needed is called: EDM C08 0000 and will give you great protection on this installation. For your Sun Tunnel Skylights, be sure to choose either the TMF 014 (flexible tubing) or the TMR 014 (rigid tubing) as these will have a "pitched aluminum" flashing base. We have some additional instructions that will show you how to integrate them into this roofing material type. Please emails us for those instructions: vcustomer.service@velux.com. Wishing you all the best on this upcoming project!

          I had my handy man install our skylight and it look great and was able to open and close the window. Then a few days later we tried to open the skylight using the hook pole and the hook eye snapped off. I wish it was made of metal instead of plastic. I placed an order with the manufacturer for a new metal eye hook with a universal hinge, because HD won’t ship to my location for a small part. Hope this helps.

          Great skylights - no need to look elsewhere
          [This review was collected as part of a promotion.] I just had 2 solar skylights and solar shades installed as a replacement for existing older skylights. The difference is stark. The new skylights are clear and having the bonus of solar energy makes us feel good, knowing that we are at least helping the environment, even if it’s a small impact. Additionally the solar required no wiring which was really nice.

              Just what I needed!
              This venting skylight replaced a 100-year-old fixed skylight in my attic space. What a difference fresh air makes, not to mention that it is remote controlled. The space is so improved that I think I will finish it and make and additional room.

              Kitchen transformation
              I replaced the original skylights with the solar powered fresh air skylights wnd WOW! It’s the first time since I purchased my home that my kitchen has been this bright, and now I can vent the windows when I cook to release the heat in there as well. This was part of my kitchen upgrade and I am so glad I went with them. I can’t believe how much light I was missing, because the old ones required the 10 ft poll to just open the shade, and neither I nor the previous owner had ever opened them.

                Over the Moon or Sun Happy
                So very happy with our new Solar Shade SkyLight. Totally blocks the sun and easy set up. I will be ordering more shades for my other skylights. No more tarps on the roof all summer long. Thank you Velux

                  We transformed a never-used dark den into the most inviting sun-filled room of the house. We used three solar powered venting skylights side by side with a shelf for all of my plants. It’s not yet painted or styled, but it already looks amazing.
                  Response from Customer ServiceJun 7, 2022
                  Thank you for the feedback! It is amazing to see how VELUX skylights can make such a transformation and turn an otherwise uninviting room into a favorite place. Thanks for the visual proof and enjoy the fresh air and daylight!

                    Replaced existing Velux with this unit
                    These 2 units were purchased as equivalent sized replacement for older failed Velux units. The original units had wood clad interior, very nice looking. These have white vinyl interior trim, which is not explained in the description on line. However, they do look nice. They were not quite an exact replacement, and we did have to cut back the shingle roofing about an inch on all sides to accommodate the flange (deck mount). Also, the flashing kit isn't really designed for replacement, just for new installation, so we had to modify that application, but I'm confident it will work fine and has so far proved watertight in the recent rainstorms here in the PNW springtime.

                    Wonderful solar powered skylights!
                    We finally have the amazing solar powered "fresh air" skylights up and running and we couldn't be happier. We love everything about them. The remotes are great! They are smooth & quiet when operating which is great. Having the black out shades is a bonus on sunny or hot days. Being able to see the sky, birds, and the stars is divine. We love the rain as well so we can not wait for the rain this year. Overall, they brighten my day up literally and figuratively! Very satisfied and pleased. Thank you Velux!!
