About This Product

This VELUX fixed FCM skylight with the Go Solar option includes a pre-installed solar powered room darkening blind and an internet gateway, allowing you to control the blind with your smartphone and enable automatic programs that boost energy efficiency. The solar powered blind is designed to harness the power of the sun to control the amount of daylight entering through your skylight. Installing a skylight is one of the most impactful ways to enhance the brightness and beauty of a room. Bringing natural light into a home through a skylight decreases the need for artificial light while maintaining privacy. FCM skylights are ideal for replacing existing curb mount skylights, including old plastic bubble skylights. This model can be installed on a site-built curb on a flat roof or up to a 60° roof pitch.


  • Eligible for up to a 30% federal tax credit on both product and installation costs, making this product very affordable
  • Room darkening blind (included) 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
  • FCM 2246 models are designed to fit a site-built curb (not included) with outside dimensions 25-1/2 in. width x 49-1/2 in. length
  • Qualifies for a 10-year "no leak" installation warranty when installed with ECL flashing on a shingle roof with a pitch between 10° - 60° or ECW flashing on a tile roof with a pitch between 14° - 60° (flashing kits are sold separately)
  • Features clean, quiet and safe Low-E3 laminated glass with a neat glass coating that keeps your skylight cleaner, reduces unwanted outside noise and comes with a 10-year hail warranty against glass breakage
  • Consists of double paned argon gas filled Low-E3 glass that provides excellent energy performance for year round comfort, plus the added safety of laminated glass, which building codes require for out of reach applications
  • Along with an internet gateway, a basic remote control is also included to operate the blind

Questions & Answers

Q:If I buy/install 3, is there a way to link all three blinds so they use 1 switch. This would be preferable, so I don't have to mount three switches on the wall takes up too much room.

1 Answer
Answer This Question

A:  You can pair multiple blinds to one remote, but it will operate the blinds simultaneously. We offer a VELUX Touch remote (sold separately) that will allow for independent operation of all skylight/shades.

    A:  Robert, the rough opening is the same as the inside curb 22 1/2 x 34 1/2. The outside curb dimension is 25 1/2 x 37 1/2. We appreciate your question and hope you enjoy your new curb mounted skylight. You will enjoy the light and the options you get from your solar powered shade.

      A:  VELUX Solar shades are stand alone and do not require wiring. Should the shade stop working, they can be moved manually. Thanks for your question Robo.

        Q:Can this be installed on a metal roof? And is there an installed night?
        by|Nov 2, 2023
        1 Answer
        Answer This Question

        A:  The VELUX curb mount skylight can be installed on a metal roof between the pitches of 0-60 degrees. The installer will have to fabricate the flashings which makes for an easy and uniform install. The blinds can be installed at a later date as well. For more questions please contact 800-888-3589.

          Received damaged product thrice
          I am so disappointed with HomeDepot and this product. It's been 2 months I have ordered this and first one returned from a UPS facility saying broken piece showing status as delivered. No refund or update to me was sent. next 2 times it came with a broken solar blinder. Velux expert says it is broken. No good instruction is available on how to install such a pre assembled solar blind, looks easy, but the frame is defective, maybe returned pieces. The issue is still going on.

            I’m a contractor so it was super easy to install and looks great. It was a big upgrade from the deck mounted velux skylight. That was there for 30 years.

            Good Quality Product
            [This review was collected as part of a promotion.] I recently had my cottage reroofed and replaced two existing skylights with two Velux fixed Skylights. They look great, are well constructed and look like they will hold up for a long time. The price was also very reasonable.

              Outstanding craftsmanship
              [This review was collected as part of a promotion.] Installed this past summer and I love the light it provides in our loft. Velux products are so well made and they stand behind their products. Wouldn't think of installing any other brand.

                Great features love them
                We purchased 4 replacement fixed skylights and they are awesome. The features have been improved over the years and they look sound amazing. So happy with the upgrade

                        Beautiful addition to my home
                        [This review was collected as part of a promotion.] I am just in the middle of renovating my house and decided to go the extra mile and put in the skylights. I am so glad i did. They bring so much light into the rooms. I love that the blinds are solar powered too and can use the remote to open and close them. Great product.
                          Good warranty.
                          We replaced the old ones with the New Velux and glad we did.
