DIY Spray foam kits?
I want to insulate the underside of a staircase that is exposed to our garage. There is a lot of cold air / drafts during the winter months. I've talked to spray insulation companies and it's not worth having them come out unless it's a large job. Are there DIY products that allow me to apply spray insulation (besides a bunch of spray cans)?
I'm talking about the foam spray; not the loose fiberglass stuff.
