Is this a legitimate framing technique?
I've made a rather horrifying discovery about my house. The wooden frame is covered in many (or most) places only by stiff foam insulation and vinyl siding. There is no wood board nailed on top of the frame. So if I'm ever locked out, all I have to do is rip off some siding and foam board, and then pull out the fiberglass insulation and punch through the dry wall.
Is this legit? I'm making the assumption that board nailed to the frame will make for a more solid house. This house has always had problems with nail pops and drywall seams. During a very severe wind storm in the past I actually felt the house shaking on the second floor. We are the 4th owners. House was built in 1990. I suspect the other owners just had the drywall repaired and repainted prior to selling.
There are at least some places where there is board, but it always seems to be either the board or the foam, never foam on top of the board.
What do y'all think?
