Why I went with spray foam over batt insulation in my Edmonton basement
I spent weeks going back and forth on insulating my basement in our 1950s bungalow near Whyte Ave. Everyone said batt was cheaper at about $0.80 per square foot, but I bit the bullet on closed-cell spray foam at $2.50 a square foot. Three months in I can already tell the difference - the basement stays way warmer and I don't feel any drafts near the rim joists. Has anyone else made this switch and noticed a big change on their heating bills?

Yeah I actually read this article from the Building Science Corporation that said spray foam does a way better job at air sealing than anything else. Sounds like you dodged a bullet with those rim joists because batt insulation just leaves gaps that let cold air sneak in. I did my attic last year with spray foam and my furnace runs less often now, even on those -30 days. That initial cost hurt but it's basically paying for itself every winter.

That spray foam really locks in the heat way better than anything else I've tried...
