i would like to beef up the insulation on our sunroom ceiling and i thought that a layer of rigid foam board with some half inch plywood and shingles on top off that would do the trick as well as somewhat soundproofing the room from rainstorms that can be deafening. the ceiling(interior and exterior) is a thin gauge aluminum and i am not sure how to attach the foam board/plywood to it. what type of fastener would work best or combination of fastener and adhesive...i am thinking of a fine thread type of sheetmetal screw might work. thanks, cj
