Hmm...
these look interesting, and we called to get some pricing. Our screened in porch is just screens... 4 feet wide and 6 feet tall. It would cost a small fortune to put windows in there, but hopefully these will be cheaper. I'd gladly pay $2k instead of $10k!!
Even though our hot tub isn't in the screened-in porch, I would wonder if there would be condensation issues or some such thing...?
