"My vinyl frames got brittle over time, especially during deep freezes..."

Yeah, vinyl can definitely get cranky when the temps drop way down. I've seen it happen a few times—one homeowner had frames literally crack after a particularly nasty cold snap. Wood's solid, but have you ever tried fiberglass frames? They're pretty resilient in extreme cold, and bonus: no messy caulking nightmares (well, fewer anyway...). Curious if anyone's given fiberglass a shot in harsh climates and how it's held up over time.

I've been skeptical about fiberglass frames myself, mostly due to cost and unfamiliarity, but after my first winter with vinyl, I'm reconsidering. We had a couple of brutal cold snaps here, and I noticed some stiffness and creaking in my frames—not exactly confidence-inspiring. From what I've read, fiberglass has a lower thermal expansion rate than vinyl, which might help avoid those brittle cracking issues. Still not totally convinced they're worth the extra investment, but your experience makes me think it might be worth looking into further.

I had a similar experience with vinyl frames a couple winters back—nothing catastrophic, but definitely some noticeable creaking and stiffness during those really cold mornings. Honestly, it made me wonder if I'd made the wrong choice. A friend of mine went fiberglass last year, and he swears by them now, says they're rock solid even at below-zero temps. But I'm still on the fence, mostly because of the price difference. Has anyone actually seen fiberglass frames hold up better over several winters, not just one or two? I mean, vinyl's been around forever, and plenty of folks seem to do fine with it. Maybe there's a trick to installation or maintenance that helps vinyl frames handle the cold better...?

Could be onto something there. I've had vinyl frames up here in Minnesota for about 8 years now, and yeah, they creak a bit when temps really dip, but nothing alarming. Honestly, proper installation seems key—my neighbor had issues until he redid the sealing and insulation around his windows. Fiberglass might be sturdier, but I'm skeptical it's worth the extra cash unless you're dealing with extreme conditions year-round.

Yeah, this matches my experience too. I'm up in Alberta, and vinyl frames have held up fine for me, even in some brutal winters. The trick seems to be making sure there's enough room for expansion and contraction when installing them. If they're jammed in too tight, that's when you get cracking or warping issues. Fiberglass might be tougher overall, but good vinyl windows installed right should handle most cold climates without much fuss...

Interesting points, but I'm not totally sold on vinyl for extreme cold. A few winters back, I helped my brother swap out his vinyl windows after they got pretty brittle and cracked in northern Minnesota. Granted, they weren't top-of-the-line models, but still... it left me skeptical.

From what I've read and seen, fiberglass seems better at handling temperature swings without losing structural integrity. Vinyl might be okay if installed perfectly, but fiberglass frames seem to give you a bit more margin for error—especially if you're dealing with really harsh winters year after year.

Also worth considering is thermal performance over time. Vinyl can warp slightly or shrink, creating tiny gaps that reduce efficiency. Fiberglass frames expand and contract similarly to glass, so the seal stays tighter for longer. Might be pricier upfront, but could save headaches down the road.

Yeah, learned that one the hard way. Our first winter in the new place, I thought the whistling noise was ghosts... nope, just cheap vinyl windows shrinking. Fiberglass next time for sure.

Fiberglass is definitely a solid choice, but don't completely write off vinyl just yet. I've had decent luck with higher-quality vinyl windows—properly installed, of course. The cheap stuff though... yeah, that's ghost territory for sure.

Good point about vinyl. I've had fiberglass windows for years now, and they've held up pretty well through some seriously harsh winters. But my neighbor installed some higher-end vinyl ones a couple of years back, and honestly, they seem to be holding their own just fine—even in the nasty cold snaps we've been getting lately.

Still, I wonder how much of that is due to installation quality versus the window material itself. Seems like even great windows can underperform if they're not sealed up properly. Has anyone noticed if certain brands or installation methods make a noticeable difference in extreme cold climates? I'm thinking about replacing a couple of basement windows soon, and it'd be helpful to hear what others have experienced before diving in again...

Totally agree with this. I've seen some top-notch fiberglass windows installed poorly, and they were drafty nightmares in winter. Meanwhile, my cousin put in mid-range vinyl ones but spent extra time sealing and insulating around them—huge difference. Makes me wonder if the install matters more than the brand sometimes...maybe it's worth investing a bit more in a careful installer rather than just premium materials?
