Aluminum’s a nightmare in cold climates. I replaced some old ones for a client last winter and the frost line inside was wild. Felt like you could keep ice cream on the sill.
That’s the truth. I had aluminum sliders in my first house, and every January the tracks would turn into little skating rinks. You’d wake up, try to open the window, and it’s basically glued shut with frost. It looked cool, but not when you’re trying to get some fresh air and end up with a puddle on the floor.
I’ll throw in a vote for good-quality vinyl, too, but I’ll admit I was skeptical at first. The cheap stuff feels like it’d crack if you looked at it wrong, but the mid-range and up has held up in my place for almost a decade now—no warping, and way less drafty than the old wood frames. Wood looks nice, but if you’re in a spot with big temp swings or any hint of moisture, you’re just asking for trouble. Mine started peeling and swelling after about five years, even with regular touch-ups.
About expanding foam... learned that lesson the hard way. My basement window looked like a failed science experiment for weeks. I’m convinced the can lies about how much it expands. Now I use the “low-expansion” stuff, and even then, I go slow. If you overdo it, you’ll be chiseling foam off your trim till spring.
On condensation, I hear you—my kitchen windows fog up every time I make pasta. I’ve tried cracking a window, but in February, that’s just trading steam for a face full of arctic air. At this point, I just wipe them down and call it good.
If anyone’s on the fence, I’d say pay a little more for solid vinyl or fiberglass, especially if you’re dealing with real winters. The install is half the battle, though—if it’s not level, you’re just setting yourself up for headaches. Shims are great, but if you’re building a tower, something’s gone sideways.
Anyone else ever tried those interior storm window kits? I used one in a pinch and it actually made a difference, but man, they look a bit sad after a month or two.
You nailed it with the foam—those cans are straight-up liars. First time I ever used one, I thought “just a little more can’t hurt,” and ended up with a window that looked like it belonged in a haunted house. I’m with you on vinyl, too. The good stuff is way sturdier than folks give it credit for, and the drafts are basically gone. The only thing I miss about wood is the look, but not enough to deal with the maintenance every year. Those plastic film kits work in a pinch, but yeah, after a while they start to sag and look kind of sad... still, better than nothing when it’s -20 out.

That’s fair, but I’ll be honest—I still haven’t totally given up on wood. Yeah, it’s a pain to scrape and repaint every couple years, but there’s something about old wood frames that just fits with my 1920s place. They’re drafty if you don’t stay on top of them, true, but I’ve found if you do a good caulking job and storm windows, they can handle even the nastiest cold snaps. Plus, if one gets dinged up, you can usually patch it up instead of having to swap out the whole window.
Vinyl is definitely easier (especially for folks who don’t want to be out there with a paintbrush), but I’ve had a couple cases where it got brittle and cracked after a decade or so—maybe our temperature swings are rougher than most. I guess nothing’s perfect. At least those plastic film kits are cheap enough to slap up when you’re in a pinch... even if they do start looking like cellophane ghosts by February.
I get the nostalgia for wood, but honestly, I’ve been way happier since switching to fiberglass. Yeah, it’s pricier up front, but I haven’t had to touch them in ten years—no swelling, no warping, and they look pretty close to painted wood if you squint. I used to be out there every spring sanding and repainting the old sashes and, man, that gets old fast when your winters are as brutal as ours.
Vinyl’s a mixed bag for me too. Had a couple of those “budget” windows crack on me after one polar vortex, so I hear you on the brittleness. Fiberglass seems to flex a bit with temp swings, which helps. Only downside is if you do mess one up, repairs aren’t as DIY-friendly as wood. But I’ll take that trade-off for not having to baby them every year.
Funny enough, I still slap up those plastic film kits too. They’re ugly, but when the wind’s howling off the lake, I’ll take function over form any day...
- Had similar issues with vinyl—looked fine for a few years, then one winter they started cracking around the corners.
- Tried wood repair for a while, but honestly, sanding in March when it’s barely above freezing got old quick.
- Switched to fiberglass three seasons ago. Noticed they don’t sweat as much on the inside, which helps with mold.
- Still tape up the plastic film every November. Not pretty, but you can’t beat the difference in draftiness.
- Only gripe: finding a matching color for a small fiberglass patch was a pain. Worth it for less maintenance, though.
- Had the same problem with vinyl—looked solid for about five winters, then suddenly started splitting at the corners. Noticed it always happened after a deep freeze and thaw cycle.
- Tried patching with caulk, but it just made things look messier. Didn’t last long either.
- Wood windows were in the house when I bought it. They look great but honestly, the maintenance is brutal. Like you said, sanding/painting in cold weather is miserable. Gave up after two years of that routine.
- Swapped to fiberglass on the north side three years back.
Same here—condensation dropped way down. Huge difference for keeping black spots off the sills.“Noticed they don’t sweat as much on the inside, which helps with mold.”
- Still use shrink film in winter too. Not pretty, but it works better than any draft stopper I’ve tried.
- Color matching on fiberglass repairs is a pain for sure. Ended up settling for “close enough” and nobody’s noticed unless I point it out.
Quick rundown:
- Vinyl: low maintenance at first, but cracks eventually
- Wood: looks best, highest upkeep (especially in freezing temps)
- Fiberglass: less hassle, decent insulation, not perfect for repairs
If I had to do it all over again, probably would’ve just bit the bullet and done fiberglass everywhere from the start. Cost more upfront but less headache each winter. Still not sold on composite windows—anyone actually have those hold up long-term?
“If I had to do it all over again, probably would’ve just bit the bullet and done fiberglass everywhere from the start.”
I hear you on that. I went with composite on the south side about seven years back—mainly because the installer talked up the “maintenance free” angle. Honestly, they’ve held up better than vinyl, but I did notice some fading and a bit of warping near the bottom after a few harsh winters. Not catastrophic, but definitely not as bulletproof as advertised. Still, way less hassle than repainting wood every couple years. Curious if anyone’s had composites last a full decade without issues? I’m not totally convinced yet.
Yeah, I get where you’re coming from. I did a mix—fiberglass on the north side, composite on the west. The fiberglass ones still look brand new after nine winters, even with all the ice and wind. The composite, though... not terrible, but there’s definitely some fading and a couple spots where the trim’s got a slight bow. Not enough to panic over, but it bugs me.
I remember thinking composite would be the sweet spot—less maintenance than wood, not as plasticky as vinyl. But honestly, if I had to do it again, I’d probably just shell out for fiberglass everywhere. It cost more up front, but I barely think about those windows now. Still, composite’s not a total bust—big improvement over the old wood frames that needed painting every other year.
Guess it depends on how much hassle you’re willing to put up with. For me, I’m done with repainting anything that faces north.
That’s interesting about the composite trim bowing a bit—seen that myself, especially on the sunnier sides where things expand and contract. Fiberglass really does hold up, though, even if the sticker shock hurts at first. Have you noticed any difference in drafts or condensation between the two? Sometimes the frame material can mess with how tight the seal stays over time, especially after a few freeze-thaw cycles.
“Sometimes the frame material can mess with how tight the seal stays over time, especially after a few freeze-thaw cycles.”
Yeah, I’ve noticed that too—my old wood frames were drafty as heck by the third winter. I swapped out a couple for fiberglass last year and honestly, way fewer cold spots around the edges now. Haven’t seen much condensation either, but maybe that’s just luck? The composite ones in the bathroom still get foggy sometimes, though. Anyone else have issues with certain rooms more than others, or is that just my weird house?
