My shop has a steel roll-up "garage" door that faces a blistering
sun for several hrs/day. I'm determined to insulate it. The
easiest way I see is to slap some styrofoam shhet insulation onto
it.
I can get 4' X 8' sheets at Big-Box for a good-enouhg price, but
need to trim the sheets down to ~ 44" X 22" to fit into the recesses
of the door.
What's the best way to cut 1-1/2" or 2" styrofoam sheets? I don't
have a "hot wire" cutting tool.
Use a very sharp thin long knife blade with a smooth low angle
slicing motion. You have to slice it smoothly in several passes.
Flexing the foam to open the cut slightly on later passes will help
ease the knife passage.
I was told that an electric carving knife would work well on the blue
foam board. I bought one at a good will and it does cut it cleanly but
it is pretty slow. Will probably just use it for trimming and build a
hot knife.
