A couple of these made their way into a surplus lot I bought and I'm wondering what they are:
About 5' tall by 3' wide and about a half inch thick. Both sides look to be fiberglass with some sort of gypsum looking clay/dust stitched between them. One has grommets for hanging. At first I was almost thinking some sort of spall-liner but it doesn't have the integrity for that so I'm thinking fire insulation perhaps, it's an odd shape though.

Any guesses?
