What spray-on insulation should I use under my house?
I live in a 100 year-old house on a pier and beam foundation with wood floors. The floors are rather cold in winter and I’m thinking of having foam insulation blown on the underside. While I want the best R value I can get, I’m concerned with toxicity as well as environmental damage. Also, should I be concerned about damage to the wood? Thank you.
