I am replacing old ( brand unknown) skylights with these. There are 3 skylights side by side with the space between them is 4.5 inches ( 3 joists). Will these fit that close together? What is the actual outside width and height?
Asked by: johnny
There are several different sizes of Velux skylights. For the best measurements, go onto the manufacturer's website and look at the specs for the skylight size that you are interested in. You could also see for yourself - go into the store and measure an actual skylight. My experience with them is that they do not protrude out far from where they are set. You may have to modify the flashing a bit, and I do highly recommend using the Velux flashing, but that isn't a huge deal. If it were summertime, I'd crawl out on my roof and measure for you. However, it is 12 degrees outside, and that just isn't going to happen. Sorry!

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!

It depends on which skylight you purchase. There is a chart available on the Velux website that details dimensions. Here is a link to the one for the manual fresh air skylights: http://www.veluxusa.com/products/skylights/manual

Does Velux make a 4' x 4' skylight?

Asked by: Red
It depends on which type of skylight you want. On the Velux website, each type of skylight has a chart showing what sizes are available. They do carry curb mounted products that are 46"x46" on the inside. Here is a link to the chart for the manual fresh air skylights: http://www.veluxusa.com/products/skylights/manual

21 x 37-7/8 in. Fresh Air Venting Deck-Mount Skylight with Laminated Low-E3 Glass is rated 4.5 out of 5 by 12.
Rated 4 out of 5 by from Shipped in a very timely manner. One flange on one... Shipped in a very timely manner. One flange on one side of 4 skylights received was somewhat bent but rather insignificant by itself. Removal of sash is not suggested but almost necessary in some installations. If you remove sash, do not put the weight of it on it's corners, leaning up against something. Regardless of how carefully you do, the weight will chip/crack the plastic corner covers hiding the metal seams. Lay it flat on it's inner frame. Overall happy with them. Four installed during a great week of weather and afterwards tested with 7 inches of rain over the course of the following week. No leaks, and given the "system" used by the flashing kit, it wasn't a cross your fingers, I was rather confident there wouldn't be any. I am reasonably handy yet this was my first time installing skylights.

Rated 5 out of 5 by from Best bathroom skylight! This skylight is now in our master bathroom and I love it! It even allows the night sky to be a natural "night light". Be sure to buy the Flashing Kit and the Manual Telescoping Control Rod too.

Rated 4 out of 5 by from great product except for one small thing Nice looking window; installation was not a problem, was installed professionally. Only bad thing is the hook for opening and closing the window. the hook was made of plastic, and it snapped the first time we used it (with telescoping crank). We replaced it with a metal hook that we purchased from Amazon ($7) and that seems to work fine.
