Just got myself a PL to make a PLUQ. Found this stuff in Home Depot, wondered if anyone had ever used/heard of using it for insulation?

It's really light and thin; not very lofty, but does seem to retain heat (I wrapped it around myself on the couch and got very warm very quick).

It says its made of paper and polyethylene. It doesn't feel like paper but what do I know. I guess because it's an absorbent dropcloth, it could pose condensation issues.

I was hoping it could be a poor-man's IX alternative. What do you guys think?
