I have a client with an existing screened porch but very poorly done (materials and workmanship). I want to re-create this with details that work, especially letting the water get out (where it has a knee wall). Where can I find details to make this work properly? Of course, this is always in keeping with a budget.
a few more details might help. Also if you hit the search thread on this site and punch in something along the lines of screen porch systems or something along those lines there is some discussion about them. This would be information and opinions of a couple of readily available systems.
first of all I am going to guess the slab has a slope so the water could get out of the room?
Second I would suggest the old fashioned approach that you would find an old porch with a knee wall on it. Around here the approach is to put a small opening at the bottom of the knee wall. They then have a little door that is placed in front of the opening to keep bugs out but when it rains is pulled out of the way.
