I am thinking of paneling the ceiling with styrofoam sheet about two inches thick. I 've got some good quality styrofoam (smooth - not grainy) I coul just glue there.
My question is about the lights. I haven't yet selected any lights but other rooms have recessed halogens lights eyebulb style.
Halogens tend to get hot and styrofoam could melt . How much room should I cut for the 50w lights? (a ball park estimate)
