Bay window framing

We have a straight two sides double hung and center is picture window. We would like to create a framing in shape of bay window and use three double hung windows. Any ideas how would i do framing for bay window look and use double hung? Want to make sure i take caution that in future it does not leak. Two double hung window size is 36 and picture window is 48 inch making it total of 120x50. If i order a bay window its going to be very expensive so i am thinking of framing it like bay window and use 3 double hung windows. Please advise.

This is a little more complicated than you might think.

First off, a bay is like a cantilevered box (with angled sides)... so you need to ensure that it can't sag. This is usually done by means of steel cables though the mullions (the space between your windows).

Second, the head and seat need to be insulated, or it will be cold and frosty in the winter, and the finish won't last.

Third, you need to do the math and figure out the layout of your windows... if your overall size is 120" wide, I would advise you to track down a supplier that will sell you a 10' long piece of birch or oak plywood. You will use this for your head and seat.

Finally, you didn't say if this is going under a soffit or if you will need to build a roof for it. You also didnt say what kind of windows you are building this out of. Wood, vinyl, nailing fin, etc.

I have done this many times, but it's not really something I want to type out blow by blow. There are too many variables, too many ways to do it. Maybe some of what I said will get you going.

I agree with Brant. Support is of the utmost importance. It is very complicated, but doable. Maybe you could post pictures of your proposed area, inside and out of the house so we can see what you see. Fill in his questions, also, which will help. http://www.doityourself.com/forum/el...your-post.html

NO way would I suggested this one for a first time DIY or even a an advanced one.
Looked into bow instead of a bay window?
They do not hang out so far.
It's well worth the extra money to just buy a factory built unit.
Far faster to install, it's not going to leak.
