installing windows side by side in open porch

We would like to enclaose our porch and there are 2 big spaces on the sides of the porch that would require an enormous window - 12' by 12' and we can't find one that is inexpensive. As we want as much light as possible we want to install 3 separate windows (from Home Depot or Lowes) in this space. What material do you recommend for the frame supports in between the windows?

Welcome to

You're right -- there is no such thing as an inexpensive 12' X 12' window!! (And if it were right at the floor, it would have to be tempered glass -- the price is even worse than you imagined!!!)

You simply need to frame the opening down so that 3 smaller windows can be installed in it. Since the opening is 12' tall, use 2X6's for the framing material. (It's too tall to use 2X4's!!)

I would suggest 3 single (or double) hungs, probably 3050's. Frame the sill AT LEAST 24" above the floor, so that you avoid needing tempered glass. And make sure that none of the windows is within 24" of a door -- same reason.

You have plenty of wall height -- you could even add three transom windows above if you so choose. Same width, just not as tall, and fixed -- picture windows.
