I am finishing out my shop and need help with the ceiling. The actual
structure is one of those portable metal buildings (14'x28') with a
gambrel style roof. I insulated the sides with r19 insulation and
covered with enameled hardboard. I also insulated the ceiling by
placing r19 paper backed fiberglass batting between the rafters (48"
centers). I am now looking for a good clean way to cover up the
sagging/swagging insulation suspended from my ceiling. As I understand,
leaving the paper backing exposed is also a building code violation.
I tried the hardboard on the ceiling too but quickly stopped for 2
reasons: 1) It also sagged. 2) The day will come that I intend to move
the structure so keeping the weight down is important to me.
I considered using the foil covered foam sheets but I read that this is
also against building code. Sheetrock will be very difficult because of
the gambrel style roof (as opposed to strictly horizontal) and I am
mostly doing it by myself (could call a friend if I really really get in
a jam). I don't want to use a suspended ceiling because I don't want to
lose any remaining ceiling clearance. It is about 8' on the edges and
12' in the center.
Consequently, my criteria- in order of importance- are adhering to
proper building code regulations, weight, cosmetics (ability to
withstand dust), durability, cost and the ability to put it up alone.
What suggestions/thoughts does anyone here have?
Thanks in advance.
