Customer Questions & Answers

I have old skylight and the size 28 inch wide and 52 inches long, I measure from the outside and it is installed side

Ways as shown to in the picture , can I use this kind of model velux fresh air venting deck mount?
Asked by: Joe
Since our Deck Mount Skylights have a definitive top and bottom, you will not be able to turn this sideways on your roof deck. If you orient our Deck Mount Skylight sideways on your roof deck, it may cause a leak and void your warranty. Our only Venting Deck Mount unit that is horizontally longer is the VS S01, which is 44-3/4" wide x 27-3/8" tall. Another option is to have a custom made FCM (Fixed Curb Mount) unit. The FCM fits over a site-built curb. To order this specific model, you will need to visit your local Home Depot store and provide an Associate with your outside curb dimension. I hope this information is useful to you. Thank you for choosing VELUX!

Does this have a screen to keep out bugs when open? Also, can this be used as a replacement cover of an existing skylight that just needs a new cover?

I am having a new roof installed and need to replace the skylight cover. I would like to use a venting cover rather than the stationary one I currently have.
Asked by: bb77
Yes, this item does have a screen to keep bugs out and it cannot be used a replacement cover.

Which flashing kit do I need (for this skylight deck mounted)

Asked by: SkylightMike
Thanks for the answer. However, I was told by your phone representative that I need a ECB flashing kit for a deck mounted skylight. Is that incorrect?

21 x 26-7/8 in. Fresh Air Venting Deck-Mount Skylight with Laminated Low-E3 Glass is rated 4.7 out of 5 by 37.
Rated 5 out of 5 by from Velux VS-C04 Velux is best in skylight business. Purchased manual venting (deck mount, with optional velux flashing kit) to replace existing (non-velux), leaking skylight above 2nd floor bedroom. Had new velux installed by contractor found on velux preferred installer list. Smooth operation to open/close - extension handle was a must for my application. Most important: No leaks! Also, noise from rain/sleet more muffled on velux than old unit.

Rated 4 out of 5 by from Completely transformed our home! We installed two manual fresh air skylights in the top floor of our oversized bungalow last year and they are wonderful. They make the house feel and look a million times better...and our house looked pretty good before we installed them! Opening and closing is easy with the manual crank handle but the skylights do angle a bit and catch on the frame slightly as they're being closed. Anyway, still very happy.

Rated 5 out of 5 by from Velux Skylight Recently installed 2 Velux skylights in our master bedroom. They instantly change the look of our room. The skylights not only brought in so much light, but also provide more air flow reducing room temperature in the summer. They are very high quality and well made products. Absolutely love them!

Rated 4 out of 5 by from An over-all excellent choice I do wish the crank had a slightly larger handle or were somewhat faster/easier to turn, but I am happy to have a skylight that opens at a reasonable price! I also am very happy to have the screen. I wish manual shades were available (not blinds), but I have rigged up curtains so all is well.

Rated 3 out of 5 by from Disappointed in the opening angle The room has now a lot more light, and the skylight seems to withhold well in adverse weather conditions, however, I am disappointed to find that it is not possible to open the window more than a certain angle. Also, it cannot open for an emergency escape.

Rated 5 out of 5 by from We now have lots of light and fresh air We have added three skylights to our home during a remodel. The change is remarkable. A dark bathroom and kitchen are now flooded with light and ventilation, and a new bathroom has a skylight over the sink area.

Rated 5 out of 5 by from Really nice venting skylights We replaced to skylights when we redid our front roof and couldn't be happier with the Velux Skylights! They were easy to install and to use. Add a solar shade and you can't beat these for all season use!!!
