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

Thanks a heap,

I had my house covered with the foam, we cut it like drywall, score
with a knife and snap it, you could score both sides then a hand saw
for any rough left.
