Guy at the South Side Rona told me spray foam is always better than fiberglass batt insulation
I went to the Rona off Calgary Trail last weekend to grab some insulation for my basement reno. This older fella in the aisle, probably a contractor, started telling me I was wasting my money on fiberglass batts and that I should just go straight to spray foam for everything. He said it seals better, lasts longer, and has higher R-value per inch. I get where he's coming from, but I don't think it's that simple. For my dry basement with no moisture issues, the batts cost me about $150 for the whole job. Spray foam would have been $600 or more and I'd need to hire someone to do it right. Plus I've read that spray foam can trap moisture if the walls aren't perfectly sealed on the outside first. Has anyone else here had a contractor push spray foam on them even when batts made more sense for the budget? I'm curious if I'm missing something.
