Yeah, insulation is one of those things you don’t really think about until you’re living with the consequences. I’m halfway through turning our attic into a bedroom, and honestly, I almost skipped proper insulation just to save time. Glad I didn’t—my neighbor did that and now their “guest room” is basically a sauna in summer. It’s not the fun part, but it’s totally worth it.
Couldn’t agree more about insulation making or breaking these conversions. I did a garage-to-bedroom project last year and almost went with the builder’s “minimum code” suggestion, but ended up using dense-pack cellulose instead. It was a pain to install—messy, took longer than planned—but the difference is night and day. The room stays comfortable even when the rest of the house is struggling with temperature swings.
It’s easy to underestimate how much heat builds up in those spaces, especially with all the roof exposure. I’ve seen people try to fix it after the fact with portable ACs or space heaters, but that just runs up the energy bill and never really solves the problem. If you’re already opening up the walls, it’s worth doing it right the first time. Not glamorous, but you’ll thank yourself later.
Totally get what you mean about insulation—skimping there just isn’t worth it. I went with spray foam in my attic conversion, and yeah, it cost more up front, but the temp stays way more stable. Honestly, I’d rather deal with a messy install once than fight with heaters and fans forever. If you’re opening up the walls anyway, might as well go the extra mile.

I hear you on that. I went with batt insulation in my garage bedroom project, mostly because of budget, and honestly... kinda regret it? It’s fine, but the temperature swings are real. If I ever do another space, I’m biting the bullet and going spray foam too. The install mess is temporary, but being comfortable year-round is worth it.
Totally get where you’re coming from. I did cellulose in my attic conversion because it was cheaper, but honestly, I’m always fiddling with the thermostat. Spray foam seemed pricey at first, but friends who went that route barely touch their HVAC now. Sometimes you just have to weigh comfort over a little chaos during install…
