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.

      Love these two skylights! Vents the cooking moisture and heat out of the kitchen. Brings in fresh air without the bugs. I added diffuser and grid support made from fluorescent lighting plastic. Pure sunlight was too harsh.

      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.

        The skylight fits like a glove on the flashing.
        The skylight fits like a glove on the flashing. Well designed and engineered, NO hassle with alignment or fitting, not often you'll find that the flashing kits fits exact with the skylight. I bought the 22 1/2 x 34 1/2, my review doesn't seem to go under the size of window I bought, anyways, great buy. I'm not a contractor, just a handy DIY guy. Thanks.

            Just tested the hook.When I started to turn it by the rod, then it broke into 3 pieces right away. The hook is made by plastic which can not bear the twisting. Now I need to climb a ladder and use my hand to twist the hook manually every time I want to open the sky window.

              We had 2 cracked dome plastic skylights that were over 25 years old. Now buying the domed type costs more than the flat glass, so we ended up buying 4 to make them all match. These VELUX Fixed Curb-Mount Skylights fit perfectly over our existing curbs! Installation was super easy. The flat profile looks so much better from the outside. And the clear glass really brightens the room!

              We installed a pair of 22.5" x 22.5" solar-powered, fresh-air venting skylights to replace a much older fixed skylight in a vaulted ceiling. UPS delivered both units in perfect condition, arriving here in Hawaii within a few days of it being shipped. The only qualm was finding quite a bit of plastic shavings trapped between the screen and the glass of the skylight, as though it was never cleaned out before testing and packaging the units. Those were easily swept out before the final installation. The installation was easy enough. The most difficult part was finding the "on" switch. There's an opening along the bottom, inside edge of the skylight, and the small red sliding switch was recessed well within that opening. I had to use the blunt end of a barbecue stick to move the switch to the "on" position. After that, programming the remote to operate this solar-powered skylight was simple. The existing curbs for the original skylights were actually slightly undersized which meant additional framing had to be added to the outer perimeter of the original curbs. While this meant the skylights were a perfect fit, it also meant that the screens can't be removed -- because the original light shaft is smaller than it should be for this skylight. We didn't want to cut into the roof and build a whole new curb since the existing one was working fine and wasn't leaking at all. And it's not a big deal that the screens can't be removed. It can still be cleaned when necessary. What caught our attention, when we were looking for a skylight that could be opened, was that these automatically close when it starts raining. We were concerned that one day the skylights would be accidentally left open during a typical unexpected Hawaiian rain shower. Testing it with an artificial rain shower from a garden hose proved that it works as advertised. The skylights open and close slowly, taking around 70 seconds to fully open or close. The best part is that these venting skylights keep hot air from building up due to the vaulted ceiling, and allow the fresh tradewinds to circulate through the room. Time will tell as to how well they hold up. But they worked perfectly the moment they were in place.

                Well made, easy to install. Recommend curb mounted application when installing into existing rafters that might not be spaced per required rough opening. Window crank and function could be improved, ie eight repetitions opens the window an inch (something like that but don't quote me) and the crank is a loop, like the end of an eye hook.

                Works well 100% of the time!
                Two years ago, we remodeled our kitchen. Using Velux skylights allowed us to remove a window (which looked out at a neighbor's house) and install two skylights for better quality of light. These are fantastic! We actually started with two fixed skylights (due to kitchen budget overage) but then replaced one with the solar fresh air version and it's heaven! We open for fresh air and to help pull air through the house. Also helps exhaust cooking odors. The rain sensor is great - it can tell the difference between water still on the sensor from a rain versus falling rain. Living in Portland, OR, it's great to be able to open the skylight after rain has ended. And the sensor is quick to send the "close" message once raindrops fall. We're looking to install two more in our living room and also a few solar tubes in our hallway and guest bath. Great stuff.

                  Very pleased with my Velux skylights! Well-made and carefully packaged. Instructions were extremely detailed and clear. Installation was straight-forward. The lights have been subjected to several heavy rains already, with no leaking whatsoever. Highly Recommended!

                  Great but one suggestion
                  Really great - looks great, operates great - I love the solar aspects for opening and controlling the skylight as well as the blinds. Really happy with them. One suggestion: use a less dark colored screen material - as the dark color of the screens makes the blinds look grey instead of white. We have them installed high up in a cathedral ceiling and they just look grey from the inside when the blinds are closed. Defeats the purpose of ordering white blinds.

                    We were looking for three skylights windows for a project where we will show to our potential customers how we can bring the light into a dark room with skylight windows. We were choosing between Velux and Fakro. Both brands are famous in the US and have a good reputation. We ended up going with Velux due to the availability of a few discounts: 1) Velux was offering 40% Professional Discount (but ordering through them you have to pay 10% of order amount as shipping); 2) Home Depot was offering a deal of 15% off of Velux windows with free shipping. There were no deals for Fakro at the time. We bought three sets of Solar Powered Venting Curb-Mount Skylight with Laminated Low-E3 Glass Beige Room Darkening Blind (VCS 3046 2004CS01) and High-Profile Tile Roof Flashing with Adhesive Underlayment for Curb Mount Skylight (ECW 3046 0000C). Here are our Pros and Cons: Pros: 1. All items were well packaged in boxes. 2. They all arrived on time. 3. The skylights and flashings look solid. Cons: 1. The skylights come with two remotes KLI 110, one for the skylights and one for the blinds. Since we bought three windows, we ended up with SIX! (6) remotes. There was no way to order this size of skylights with universal remote KLR 200, which can operate all of these functions plus many additional functions not directly related to the skylights (eg., regular lights, etc.)… At the same time Velux skylights in other sizes (even without blinds) are available with universal remote. 2. The area all around PVC frame of skylights and the insect screens are full of scratches and dirty spots from hands. 3. The space between PVC frame and the insulated glass is full of plastic and metal shavings. There was even a screw left in-between there! As a result, plastic chips keep falling on the plastic teeth of the rails where plastic gear move the blinds up and down. As they keep getting caught there, this may result in the damage to the whole mechanism. Having these shavings also means that every time we open/close skylights more plastic pieces drop on the insect screens (and definitely on plastic rails, too). 4. We have also found some big metal shavings between the insulated glass and the rubber gasket – this means the insulation in those spots is compromised. 5. In one of the corners, the PVC frame parts are connected with 3 mm in difference in horizontal level between them. 6. In one of the skylights, the shelf for the insect screen is longer than it should be and was installed without any extra space; as a result it is arched instead of being in line. 7. Similar problem exists with the gear cover: the cover and the frame are not in level in the middle; the cover arches and creates a space in the middle. 8. Each corner of the PVC frame has an overlap (inside and out) as a result of soldering two pieces of the frame – these overlaps were not cut off. These plastic “leftovers” looks very unprofessional and ugly (unless you are planning to completely cover the frame from the inside). 9. There are also a few spots where formed aluminum sash connects with the insulation glass – in those spots the silicone sort of “leaked” outside. As result, I am more satisfied with the discount than the quality of the product. Next time, will try Fakro, when discount is available. IMHO… Fakro has two things which Velux does not have: 1. Fakro has the external blinds for the skylights, which Velux does not offer in the US anymore. There are very useful in hot states like Arizona. 2. In case the solar panel battery needs to be replaced, Fakro offers to exchange just the battery, whereas with Velux you would have to change the entire panel, which is obviously not cheap.

                    Thank you very much for providing your feedback! I have passed this along to our Quality Assurance team and they have already reviewed the information and are working with our Production team to address any issues that can be addressed. (For example, they confirmed shavings are vacuumed when assembling the skylights, but said certain skylight models have a stronger electrostatic force which prevents some shavings from being vacuumed, so they will look for a better solution.) I see that our Customer Service team is already working with you on arranging a service call, so that’s good.

                    Regarding the many remotes that were included, the funny thing is your order was submitted during a transition period during which we began moving away from including one type of remote with this skylight model and launching a new accessory that can control the skylight. In fact, it was only 9 days after your order was placed that our new VELUX ACTIVE kit (KIX 300) became available on homedepot.com. One of the many features of the ACTIVE system is it allows you to connect to and open & close your skylights and blinds through a free VELUX app on your smartphone.

                    If you are ever unable to find exactly what you are looking for on Home Depot’s website, please keep in mind that you can go to your local Home Depot store and ask a Millwork associate to special order an item for you. We have a very large assortment of products and cannot put all of them online, but our entire catalog is available through special order! Thank you again.

                      We were getting our roof done and decided to splurge a little on a couple of skylights in an area that has no windows. The roofers installed the skylights and I LOVE all the light they let into this area and down the stairway. It's an enclosed stairway and can get fairly dark so we leave the light on all the time. During the day we no longer need to do this! I love that they open so we can vent the upstairs and I love that they are not too much. I love the size of them. We've only had them installed for a few weeks and we've had some pretty substantial rain in that time without any leaks or condensation. So far so good.

                        The skylights are really nice and were easy to install 6 in total. The bad was the flashing kits. Velux needs to figure out a better way to package and ship. Two of them were damaged (bent) I was able to fix one but the other was totaled.

                        This skylight perfectly retrofit my old 1980's Sun-Tek bubble skylight manufactured by Sun-Tek in Orlando FL during the 1980's. My old bubble light was cracking from age. Upon removal of the 30 year old bubble light my Sun-Tek curb flashing was aluminum framing measuring OD 26-1/4" top to bottom and side to side square. This skylight snugly slid onto my old existing aluminum flashing and with careful measuring, the self drilling screws securely fastened to the 1/2" aluminum vertical flashing frame face. This saved me a bunch of $$$ not having to replace the existing curb flashing. Look at the CAD PDF technical drawings on Velux website for precise measurements of the skylight so you can feel warm and fuzzy before ordering. IF you have the old bubble lights it will scare you when you see just how cheap and flimsy they were made leaving your house interior vulnerable to hurricane/rain damage. Spend the money to replace them with Velux skylights either normal tempered glass or this impact glass product.

                          Installed 2 solar powered Skylights in August. The room was dark, so the Skylights have added needed lights to the room. We added solar blinds which were a must. We love our Skylights. Looking to add another to our bathroom.

                              Window works as described. Mine came with a split gasket inside the window. I reached out to Velux about the issue and have not received an adequate answer as to what should be done after nearly a month. So as with a lot of companies, I will now have to follow up with them again. . The customer service rep could not answer my question which was then forwarded to the QC department which has not responded. Seems like a good product overall but I don't know if the same can be said of the company.

                              We had professionals install our skylights in our new roof. I was disappointed that we couldn't add another story to our home. However, the skylights open up the rooms and bring a view of the outdoors to us. We've only had them for a short time, but I love watching the changing sky. I was watching the moon and stars in our very own personal light show! As a bonus, we even get rainbows on the wall when we put up crystals. We have the skylights in the kitchen, living room and bedrooms. I appreciate the quality of the product and you certainly will, too.

                              This was a replacement for an old acrylic model that had cracked so installation was easy. It’s much heavier than the old one so getting it up on the roof took a little more effort. The rod that I used to open the old one is a perfect fit with this one. The quality of this one is excellent and will probably never need to be replaced in my lifetime.
