Went to the local home improvement store to investigate possible
approaches to insulate my steel garage door. One option is a sort of
buble wrap stuff with foil on both sides, that's supposed to be a very
good reflective barrier. The other option is poly-foam of varying
thickness.
I live in southwest ohio, where dec-feb have mostly sub-freezing days,
and the coldest days can get down to single digits or below zero... in
summer, weeks of 90s are normal.
My garage door is souther facing.
My question is this: foil, foam, or some combination of the two? And,
if you recommend a combination, which one against the steel door, which
exposed to the open space of the garage?
