The downside is you can’t open the window until spring, but to me that’s less of a hassle than constantly fussing with caulk or stuffing gaps.
That’s pretty much where I landed too. I’ve got a 1950s place, and those windows are more “suggestion” than “barrier” when it comes to winter air. The shrink film kits work surprisingly well, even if it does look like I’m living in a greenhouse for half the year. I tried rope caulk once, but it kept peeling off when the frame flexed (which happens every time the temp swings more than 10 degrees).
I do kind of miss being able to crack a window for fresh air, but honestly, I’d rather not freeze while making coffee in the morning. Also, I tried the wool sock trick once—looked like I was prepping for a sock puppet show, but hey, desperate times.
Anyone else ever try bubble wrap? I read about it somewhere and slapped some up last year. Not pretty, but it did knock the edge off the drafts.
Bubble wrap actually worked better than I expected, but wow, it’s not winning any style points. I stuck it up on my basement windows last winter—just misted the glass and pressed it on. The room felt less drafty, but yeah, looked like I was hoarding packing supplies. Anyone ever try those magnetic window covers? I keep seeing ads but haven’t pulled the trigger. I’m curious if they’re worth the hassle or just another thing to store all summer.
