The pole barn that came with our house, doesn't have a man door. The siding on the pole barn is ribbed aluminum with 1/2" vertical ribs. I purchased a 32x80 prehung door, have an exposed cavity of 36x90 on this inside, and am ready to frame and cut the siding.
My question is how do I properly seal this against the ribbed siding? My first thought (and what I'm leaning toward), is to remove the brick mold entirely and frame tight to the siding with the aluminum siding acting as the waterproofing layer. Then caulking/foaming whatever gap may be present between the siding and the frame.
Thoughts on this approach?
