I have a covered patio attached to the back of my house. It was built with the intention of enclosing it one day. I live in Dallas, Texas and we don't have severe winters, but the summers are hot. I'm trying to decide whether to just screen it in or put in sliding doors all the way around with screens. Since there won't be AC or heat piped into the room, I'm not sure which would be the best way to go. I also don't know the expense involved. Do you have any recommenations? Thanks!
