I get where you’re coming from with the caulk and weatherstripping—definitely the cheapest route, and I’ve done it plenty of times myself. But I’ve actually had the opposite experience with condensation after adding storm windows, especially the interior kind. If you make sure the storm window is sealed tight and the original window is as airtight as possible, you can cut down on drafts and condensation both. The trick is making sure there’s no air leaking in between the two layers, or yeah, you’ll get that foggy mess.
One thing I’d add: before you start sealing everything up, check for any signs of rot or mold around the frames. Trapping moisture in there can make things worse in the long run. I usually do a quick wipe-down and let everything dry out before I put up storms or slap on new caulk. Heavy curtains are great for blocking drafts, but if you’ve got old windows, sometimes you need a few layers of defense. Just my two cents—sometimes the extra step pays off, even if it’s a bit more work upfront.
That’s a good point about checking for rot or mold before sealing things up. I learned that the hard way—sealed up a drafty old window one winter, only to find out months later there was already moisture trapped inside the frame. Ended up with a nasty patch of mold that took forever to clean out. Ever tried using those removable window insulation kits? I’ve found they help a bit with temperature swings, but I’m always worried about how much plastic waste they create. Curious if anyone’s found a more eco-friendly fix for that bedroom-igloo situation...

I’ve wondered about this too, especially since those plastic kits always feel like a temporary band-aid. Honestly, I’m not convinced they’re worth the hassle every year. Have you tried thermal curtains? I’ve read mixed things—some folks swear by them, others say they just trap condensation and make the window sweat even more.
I get the concern about plastic waste. I’ve looked into using bubble wrap (the big kind) as an alternative, but it’s still plastic at the end of the day. I keep thinking there’s got to be a better long-term solution that doesn’t involve ripping out the whole window. Has anyone experimented with interior storm windows or those magnetic acrylic panels? I’m skeptical about how well they actually seal, but maybe that’s just me being overly cautious after dealing with mold once...
Tried a bunch of things over the years—plastic film, bubble wrap, even those “insulating” window snakes that my mom swore by (did nothing except trip me in the dark). I hear you about the plastic kits. They’re a pain to put up, look ugly, and then you’re stuck tossing all that plastic every spring. Not exactly eco-friendly or budget-friendly.
Thermal curtains helped a little for me, but only if I remembered to open them during the day. Otherwise, yeah, condensation city. I actually had a patch of mold sneak up on me last winter... fun times. The trick seems to be making sure there’s some airflow, but not so much that you’re letting all the heat out. Not easy.
I did try making my own interior storm window with acrylic and magnetic tape. Here’s how it went:
1. Measured the inside of the window frame (twice, because I messed up the first time).
2. Bought a sheet of acrylic from the hardware store and had them cut it to size.
3. Stuck magnetic tape around the edge of the acrylic and the window frame.
4. Smushed it into place.
Honestly? It sealed way better than I expected. Not perfect, but way less drafty and no more ice on the inside of the glass. Biggest downside was getting the acrylic clean without scratching it, and the magnets weren’t strong enough at first (had to double up). Didn’t cost a fortune, and I can reuse it every year, so less waste.
If you’re worried about mold, just make sure you wipe down any condensation that does show up and maybe crack the window for a few minutes in the morning. Not ideal, but better than replacing drywall.
I’d skip bubble wrap unless you’re desperate. It’s ugly, and it doesn’t really hold up after a season. The DIY storm window thing is probably the best bang for your buck if you can handle a little measuring and fiddling around with tape. Just don’t expect miracles if your windows are ancient and leaky like mine.

I get the appeal of the DIY storm window, but honestly, acrylic’s not all that eco-friendly either. Manufacturing it isn’t great for the environment, and it’ll eventually scratch up and need replacing. I’ve had better luck just sealing up gaps with weatherstripping and using layered wool curtains—yeah, pricier upfront, but they last forever and don’t create plastic waste every few years. Plus, wool actually breathes a bit, so less condensation drama. Just my two cents.
