About This Product

VELUX VCS solar powered Fresh Airskylights light up your home and provide ventilation using only the power of the sun. They feature a solar panel that captures any available daylight and uses it to recharge a highly efficient battery powered operator and control system. In addition, this model includes a factory-installed solar powered room darkening shade that utilizes a double-pleated honeycomb structure with an interior aluminum coating to block even the brightest sunlight, making it ideal for bedrooms, entertainment rooms or any other space where light control is important. These skylights are ideal for replacing existing curb mount skylights, including old plastic bubble skylights and can be opened to create a chimney effect, drawing air upward to improve air quality within your home. This model can be installed on a site-built curb on a flat roof or up to a 60° roof pitch.

Questions & Answers

Q:what is the difference between a curb mount and a deck mount?
by|Jul 7, 2024
1 Answer
Answer This Question

A:  It is the way the skylight attaches to the roof. VELUX deck mounted skylights attach directly to the roof deck and has a lower profile. It has a minimum pitch requirement of 3:12 pitch and can be used on a maximum roof pitch of 137:12. VELUX curb mounted skylights are installed on a 2x4 or 2x6 wood frame or "curb" that is secured to the roof deck. Similar to how the lid on a shoebox appears. This type of skylight can be used on a flat roof as well as a sloped roof up to a 20:12 roof pitch maximum.

          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.

              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!

                    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!!

                      Beautiful upgrade to our home
                      I purchased two of the solar powered skylights for our bathroom remodel. It added a depth of elegance sitting above the soaking tub.

                        Such an upgrade from the old solar tube
                        We just had this skylight installed to replace an old leaking solar tube in our bonus room that isn’t connected to our central air. As soon as we opened it, all the hot air in the room got sucked out and a nice breeze came in its place. So happy with it, and now I want two more in my kitchen.

                          Solar operated Blinds will be A BIG ENERGY SAVER
                          These things are great! Never thought blinds in our skylights would add so much to our home. Control with Phone APP Timer and wall switch.
