I've used the styrofoam you're talking about. I have 5/8" on the ceiling of my pole barn/home office. I never thought about it before, but think that'd make a great shelter.

You could probably make a little wood/charcoal stove to put in one of those. If you vented the fresh air to the stove from the outside, and used a chimney pipe, you'd probably be able to keep heat in there really good. Might get by better than Bob Cratchit on just a few briquets

You could even make some double paned visqueen windows for that shelter. That would be pretty cool.


I'm thinking of making a bivy style tent with the bubble foil. It won't pack up very small, but it will be pretty light, and should be really warm. If I can get the pack size down to that of a blue foam pad it might work pretty good.
