Putting windows in enclosed screen porch

I currently have a screened in porch on the backside of my house that has one long side and one short side screened in. the other two are house walls. The roof over this room is continued from the house (continuous) and was built at the same time, sorry for the confusion. I am looking to enclose this room with windows my self. What suggestions could anyone give on how to frame, or weather proof the bottom of a knee wall. The flooring is cement and existing, the other side of the wall would be a deck. I am looking to do this myself, as I am handy, but just need some help getting the ideas flowing! Thanks

Does the slab end where your walls are sitting, or does the slab extend beyond the border of the room? If the slab extends beyond the walls, that presents a problem. If it does, something I have done in the past is cut a kerf in the exterior cement 1" or so away from the walls. Then I bend a flashing like a drip edge, run a bead of caulk in that kerf and behind it, then set the flashing into the sealant. The flashing will extend up onto your sheathing and your building paper overlaps it.

As far as framing your walls in for windows, figure out what windows you'll get first- standard sizes will be the least expensive. You'll do the framing first, then put on some building paper, then install the windows, and it's a good idea to use some peel and stick membranes to seal the nailing flanges of the windows to the building paper.

If you are building a deck outside the room, the most problem-free way to do that is to build the deck free standing so that you don't have a deck ledger right up against the house. Ledgers mounted directly to the sheathing often create problems when the ledger is not properly flashed and incorporated with the siding.
