| Help me identify some rigid insulation
I came across a large surplus of 1" rigid insulation with no identifying marks. They're 4x8 sheets with a black paper (like tar paper w/o the tar) bonded to each side.
Do they sound familiar to anyone and do you think they'd be useful for DIY traps? Yeah, I know I can either build one and try it or stick with what I know works. However, I do have this large pallet load and would hate to see it go to waste.
