VELUX Fresh Air skylights are an energy-efficient way to bring both fresh air and sunlight into a home and make dark rooms come to life. Bringing natural light into a home through a skylight decreases the need for electricity while maintaining privacy. Installing a skylight is one of the most impactful ways to enhance both the brightness and beauty of a room.

  • Inside curb dimensions for VELUX VCM 2246 models are 22-1/2 in. by 46-1/2 in. and outside curb dimensions for VCM 2246 models are 25-1/2 in. by 49-1/2 in.
  • The VCM skylight qualifies for a 10-year no leak installation warranty when installed with VELUX ECL flashing on a shingle roof with a pitch between 10° and 60° or VELUX ECW flashing on a tile roof with a pitch between 14° and 60° (flashing kits are sold separately)
  • Features laminated clean, quiet & safe glass with a neat glass coating that keeps your skylight cleaner, reduces unwanted outside noise, is energy efficient, and has an extra glass pane for added safety
  • Consider adding a VELUX solar powered blind (sold and shipped separately) which is eligible for a 30% federal solar tax credit and allows you to control the light
  • Consider upgrading to a solar powered fresh air skylight (model VCS) to bring both natural light and fresh air into your home using only the power of the sun, plus it is eligible for a 30% federal solar tax credit, making it very affordable
  • Manual control rod (ZCT 300) or motorized control rod (ZMT 300) for venting skylights are sold separately for out-of-reach applications

Rated 4.0 out of 5.0 by Replacement of existing unit, no problem. I used this to replace another skylight and it was one of the few available that would work with the existing curb. Installation was a breeze other than having to remake part of the light well due to a slight difference the old one and this new one. This is a manually opening model. One small negative is that it takes 35 cranks to fully open the Velux. The old one took 18. It seems this one does open a bit farther though, so it's a fair trade. My one and only complaint is that Velux does not offer this skylight, indeed any other the VCM models, with a manual shade of any sort. If you want a Velux shade (which was the reason I sought out Velux originally) you must buy an electric model with remote control that costs nearly as much or more than the actual skylight. To me, an electric shade, or for that matter an electrically opening skylight, is just one more thing to go wrong. My actual curb dimensions are 26" X 38" which are a bit larger than the stated size for this unit, but it fit with no difficulty. Otherwise, it is a great product which I'm hopeful will give many years of service. September 16, 2014
Rated 3.0 out of 5.0 by product naming/sizing is confusing with a curb-mounted skylight, you'd think the measurements noted on the box are for the outside of the curb -- the box that you need to cover (outside to outside). not so. the 22.5 measurement is for the glass itself and this skylight is made to cover a 25.5in box. why is the glass size important? while this is noted in the specs here on the site, it's not particularly evident on the product packaging or the naming nomenclature at the store.... they should call it a 25.5x25.5 ... not 22.5x22.5 ... it's a great looking skylight and very well built. i just wish it would have fit.

Rated 5.0 out of 5.0 by Simple grace and delight. When we bought our house, 23 years ago, it came with two skylights, not made by Velux. Over time, they died and had to be replaced. We chose Velux for the quality and the reputation. We capture the beautiful and refreshing sea breeze whenever we open them, and enjoy the beautiful sunlight that they provide year round. These add so much to the aesthetics of our home, we could not imagine life without them. June 23, 2015
Rated 5.0 out of 5.0 by Easy open I love the easier opening this feature has. Regardless it is a manual, It is very smooth. I have disabilities that usually make it hard to use my hands. Also, I have the automatic shade. It is wonderful to have the window opened on a sunny day and be able to close the shade, so it doesn't get to hot. June 24, 2015
Rated 5.0 out of 5.0 by This lovely addition to my home is wonderful We bought this recently and I love being able to open the window into the outdoors and close it when the elements get bad. The light that comes in makes an enormous difference in my living space. I highly recommend this product. June 23, 2015
Rated 5.0 out of 5.0 by Fantastic skylight We have had our skylight for over a year. So far it is wonderful. No leaks during the rainy season. It works great, lets in lots of light and air when open. June 23, 2015
Rated 5.0 out of 5.0 by Sunny addition I had two new skylights installed and the results were terrific. It added a nice touch of sunlight in a otherwise dark room. I highly recommend this. June 23, 2015
