Insulating a metal deck ceiling

Q.  I have a small basement toilet and shower with an exposed (galvanized) metal deck ceiling. The metal deck supports a concrete porch floor that is open to the elements. We live in Pittsburgh, Pennsylvania, so the weather goes from cold/snow/ice to 100 degrees in the summer. There is an exhaust fan and hot water heat.
I would like to remodel this room and cover the metal deck, but I am worried about trapping moisture under the metal deck and causing corrosion, mildew staining etc.

I have considered spraying a closed cell urethane foam. What do you recommend?

A.  Your concern is well taken. The safest solution would be to spray closed-cell foam. Be sure that you have this done by an experienced foamer to minimize the chance of shrinkage and overheating of the mixture.

You’ll have to figure out how to install a ceiling to cover the foam. Is there enough height to build a 2×4 framework under the foam to hang drywall?
