Tried spray foam vs. fiberglass for my attic hatch insulation and it wasn't even close
Sealed up that plywood hatch with a can of Great Stuff and a foam gasket kit from Lowe's for about $15, and my upstairs doesn't feel like a walk-in freezer anymore. Has anyone else found other spots where foam just trumps the old batting approach?

Used to be all in on fiberglass for everything, thought spray foam was just overpriced hype. Then I sealed my rim joists with it last winter and felt the difference the same night. The air sealing is what gets you, fiberglass lets so much draft through it's basically just a filter for your insulation.

Fiberglass is just expensive couch stuffing with delusions of grandeur.
