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.

What do you use your sunroom for? What kind of windows are in there?

A lot of people turn porches and sunrooms into additional living space
that can be used any time. But having a sun room that works for it's
intended purpose is a joy. Which is it?

I wouldn't add anything on top of what you have. Either rip it all down
and rebuild it as regular roof, or learn to love your metal roof and
possibly add insulation underneath with construction adhesive. Adding
insulation will do little for your noise considerations.

thanks, cj

the sunroom is our living room, giving us an excellent view outback to
the woods. i have an open floor plan and the poorly insulated sunroom
really adds to our winter heating bill. we saw the original bill of sale
for the sunroom and for what the previous owner paid he could have built
the same room with all the windows ,patio door and regular stick
construction for much less. adding some rigid foamboard, particle board
and shingles would damper the sound of a summer downpour, as it is now
you have to practically yell to be heard and in the fall acorns dropping
from 30 feet up sound like gunshot in the house

Be a friend and send aemeijers a DVD/CD/Tape/whatever of the racket
your hear next time you have a summer thunderstorm occur. If that
turns out well, maybe you could market the recording and build up
funds enough for a sunroom replacement someday. just sayin'...
