Our container's insulation went from a total mess to actually holding heat

Three weeks ago we had a huge gap near the roof seam that let in a cold draft, making the whole space feel like a fridge. After sealing it with spray foam and adding another layer of rigid board, the inside temp stayed steady during a 40-degree night. What's the biggest insulation fix you've had to make on your build?

Wait, are you telling me you sealed a garage door and it STILL stayed at 40 degrees? 😂 That's basically a meat locker, man. My biggest insulation fix was crawling under the house in a full moon suit to jam fiberglass batts into every crack I could find. Still got a draft coming through the floor vents, so I feel you @anthony165 - sometimes you patch one hole and another one just appears like a bad game of whack-a-mole.

Honestly a 40 degree night is not that cold though? Like that's still above freezing. My garage stays about that warm without any extra insulation. Maybe you just had a really bad draft before and now it's just normal.

Yeah, 40 degrees is totally fine for a garage, right? My old place had a drafty side door that made the whole space feel like a freezer. After I sealed the gap with some weather stripping, it stayed right around 40 all winter without any heat.
