Funny you mention that, because when we did our bathroom windows last spring, I went down the rabbit hole of specialty foams and tapes. Honestly, it was overwhelming. Ended up just grabbing regular caulk and some shims, figuring it couldn't be rocket science, right? Turned out fine so far, but your point about prep work really hits home—I probably spent twice as long just cleaning and measuring as I did actually installing the window.
Still curious though... does anyone think specialty foam makes a huge difference in noise reduction or insulation value? Our bathroom window seems okay, but now you've got me wondering if it could've been even better. Or maybe it's just marketing hype after all? Either way, glad to hear the simple approach is still holding strong for you after all these winters. Gives me hope mine will last too, fingers crossed.
"Still curious though... does anyone think specialty foam makes a huge difference in noise reduction or insulation value?"
Honestly, specialty foam *can* make a noticeable difference, especially if noise reduction is a priority. Regular caulk and shims get the job done for sealing drafts, but foam does a better job filling irregular gaps and dampening sound. That said, it's not night-and-day unless you live near a busy street or airport...or have really thin walls (been there, done that).
Funny story, I once had a client who swore by this expensive acoustic foam for his bedroom windows. We installed it, and yeah, it was quieter—but turns out most of the noise was actually coming through his attic vents. So, moral of the story: foam helps, but only if you're addressing the right problem.
Your approach sounds totally solid, though. Good prep and careful sealing usually matters way more than fancy products. If your bathroom window feels good now, I wouldn't lose sleep over it.
Specialty foam definitely has its place, but honestly, I've found that good-quality weatherstripping and properly fitted storm windows often make a bigger difference. Foam's nice, but sometimes simpler solutions get overlooked and can save you some cash too... just my two cents.
Totally agree that simpler solutions often get overlooked. When we moved into our current place, the windows were drafty as heck, and I immediately thought we'd have to go all-in on specialty foam or even replace them entirely. But after chatting with a neighbor who'd been through the same thing, I decided to try weatherstripping first. Honestly, it was night and day. Took me maybe an afternoon to do the whole house, and the difference was immediate—no more chilly drafts sneaking in.
One other thing I found helpful was using rope caulk around the edges of older windows during winter. It's cheap, easy to apply, and you can peel it off cleanly when spring rolls around. Foam definitely has its uses, especially for bigger gaps or tricky spots, but sometimes the simplest fixes really are the best. Plus, saving a bit of cash never hurts...

Rope caulk is definitely underrated—I've recommended it to clients plenty of times. Another quick tip: ever tried shimming windows with playing cards? Sounds weird, but works surprisingly well for minor adjustments...
Rope caulk really is a lifesaver for drafty windows—glad to see others appreciating it too. Never thought about using playing cards as shims though, that's pretty clever. I've always just grabbed whatever scrap wood or cardboard I had lying around. Might have to raid the junk drawer next time and give your card trick a shot...
I've used rope caulk plenty of times myself, but playing cards? Never crossed my mind either. Wondering how well they'd hold up long-term, especially if there's moisture or humidity involved... wouldn't they warp or deteriorate quicker than wood shims or plastic wedges? Might try it on an interior window first to see how it goes. Has anyone noticed issues with durability over time using cards, or is it pretty much a non-issue?
I've actually tried the playing card trick before—more out of curiosity than anything else—and it's kind of a mixed bag. For interior windows in dry environments, they held up surprisingly well. But you're right to wonder about moisture issues. I noticed that on one window near my bathroom (where humidity spikes after showers), the cards did start to warp slightly after a few months. Nothing disastrous, but enough to make me question their long-term reliability.
Personally, I'd stick with plastic wedges or traditional shims for exterior or humid areas... they're just more robust and predictable in those conditions. Cards are great in a pinch or for temporary setups, though—plus, there's always that satisfying feeling of finally finding a use for that incomplete deck that's been floating around forever.
Good points about the playing cards—I had similar reservations. I've used them once or twice myself, and while they're handy in a pinch, I found they compress slightly over time, especially if the window is heavier or sees frequent use. Plastic wedges or composite shims definitely offer more consistent support. Another hack I've tried is using thin strips of vinyl flooring scraps—they're moisture-resistant, easy to trim, and hold their shape surprisingly well. Just something else to consider if you've got leftover flooring lying around...
Interesting idea with the vinyl flooring scraps—I haven't tried that myself, but I can see how it'd work. Personally, I've had good results using thin strips of aluminum flashing. It's rigid enough to hold up under heavier windows, won't compress, and it's resistant to moisture and temperature changes. The only downside is you need to be careful handling it—sharp edges can sneak up on you pretty quick...
I've also experimented with composite shims, and they're definitely reliable. But in tight spaces or when you need something ultra-thin, flashing can be a lifesaver. Just another option to keep in mind if you've got some leftover from roofing or siding jobs.
