        Q:I need to replace and existing curb mounted skylight. The curb and flashing appear to be in good shape. The exterior dimension of the existing 2 by 4 curb are 21/1/4" by 45 1/4". Will your FCM2246 work with this curb?
        by|Apr 2, 2024
        1 Answer
        Answer This Question

        A:  This is not suitable for this application. The FCM 2246 0004D requires an outside curb measurement of 25 1/2 x 49 1/2 inches. Your measurements are very close to the VELUX FS C06 2004D (which is a deck mounted skylight) To determine the proper skylight model for your application, please send any pictures and your measurements to: vcustomer.service@velux.com and VELUX can confirm the product needed.

          Velux will NOT honor warranty!
          I had two of these installed by a Velux contractor. In year five--last year--one leaked above the LR. Velux sent out the same installer, who blamed the fire prinkler system---which is not even near the skylights, and was found in perfect condition by my insurance adjuster! Despite the ten-year warranty, and it being only year 5, Velux refuses to fix it! Lots of complaints on BBB re this. I guess they'll next blame aliens! I'll be suing them when the rain stops.

          VELUX is committed to quality and excellence so you can rest assured that our technical solutions team has managed your warranty claim with due diligence. Neither the technician nor the department head found any indication of defects with your skylights during their inspections. It’s my understanding that we are waiting for you to provide some information that was requested in order for your warranty claim to receive further consideration, so please refer back to the communications you received. Thank you. Velux
            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
