Great Stuff (tm)
This expanding insulating foam is an aptly named product: it really is great stuff. I got a couple of cans as part of my long-running project to keep our stone basement walls from falling apart, letting in cold air, and providing condos for mice. You spray it in a crack, and it expands as it dries, filling all the nooks and crannies.
If you spray in too much, which is almost inevitable, it oozes out like some B-movie outer space killer slime. Cool.It’s very light weight when it dries, and very rigid. In the right hands – probably not mine – it has great Halloween costume potential. People who should know say that it sucks for lost foam casting, if that's an issue for you. And the gummint says you probably ought to have more ventilation rather than less.
