Debate: is spray foam insulation actually worth the hype? I'm torn after my attic project
I spent $1,800 on spray foam for my attic in Edmonton last fall and my heating bill dropped maybe $30 a month. But my buddy swears by the old fiberglass batts he put in for $400 and says his house is just as warm. So did I waste my money on the fancy stuff or did I make a solid long term bet? Has anyone else here regretted spray foam or seen huge savings years down the road?
My buddy Mike got spray foam done in his attic a few years back. Ended up with mold behind the drywall, cost him like 8 grand to tear it all out and redo it with regular fiberglass.
