I get where you’re coming from, but I actually think those “tiny stuff” gaps can matter more than you’d expect, especially in a new build or a super airtight design. Like, I spent a weekend chasing drafts in my place and was surprised how much air was sneaking in around the baseboards and even through the light fixtures. Maybe not as dramatic as the attic hatch, but it added up—my heat bill dropped a bit after I went around with some caulk and weatherstripping.
don’t overthink every single gap. Focus on the big leaks first (attic hatches, basement rim joists, around windows/doors). The tiny stuff adds up, but not as much as you’d think.
I used to think the same, but after living through a couple of cold snaps, I’m not so sure. Maybe it depends on your climate or how picky you are about drafts? Either way, I guess it’s about finding that balance between effort and payoff... but if you’ve got a free afternoon and a tube of caulk, it’s not the worst way to spend it.
