How's it going folks. I'm trying to walk-in/enclose my one of my 2 garage doors. My building is built form the early 1900s for old Jeep's to be worked on in the military (Fort Riley, KS). It's galvanized steel. I have like 5 questions. Pics and video posted. 1. When it rains, water comes underneath the bottom/sill plate YET there is no bottom/sill plate. I did add FOAM sealant but water still gets in. I tried using drip edging and it's so tough trying to match the slits I cut into the sheet metal so it's a constant fight. I also TRIED cutting the drip edge every 15 3/4" to fit between the metal studs BUTTTT it has gaps on the outside and it looks awful. I THINK my next move is to spray flex seal (oh yeah I used silicone to caulk air holes. Wmhow can I get that drip edge to work? 2. How do I take this spring off without getting hurt? This is the where I'm building that wall! 3. Where that wall is going up, the studs are 8' 1". The top of the angle iron is like 7'4" or close to it. The PROBLEM I'm having is what do I attach the suds to since there is NO TOP PLATE and there is a 3 1/4" gap behind the 2x4 wall stud so again, what do I attach/anchor the wall too so it's secure. I'm wanting to insulate the building as well. Please Help???
