Custom size window for DIY project

I am having problems finding the size of window that I need. The current window is 100w and 78h. I currently have a small sag and in the old current window and need to put in supports so the roof will stop sagging so much. Does anybody know a manufacturer that makes windows that large? I actually need two casements that are 24x78 and a picture window or casement 48x78 to make room for the supports. I did get a bid for a Midwest Alliance window but have not heard good things about them.

I don't know of anyone that makes a casement over 72" tall. At least not in a vinyl. Even in an aluminum I can only find one at 76"

Simonton makes casements up to 80" tall.

Interesting. I'll have to ask my supplier about that. I can only imagine what the price is.

Page 13. They are priced the same as any casement over 101 UI.

Price isn't as bad as I thought it would be.

I did go with the Simonton 5500 casements. I went ahead and upgraged to the super spacer and low E 366 instead of the prosolar package that they quoted. The windows are very nice and the casement work very well. The low E 366 gives a tint to the window. The window worked so well that I am now upgrading all my windows.

Thanks for posting back again after the install. Glad you are happy with the windows.
