- Swapped out two windows last fall—one vinyl, one fiberglass, both in 1950s frames.
- Honestly, didn’t notice much difference in noise unless I went with thicker glass.
- Fiberglass felt sturdier and maybe a bit tighter for drafts, but price was rough compared to vinyl.
- If the old frames are a mess, vinyl’s so much easier to wrangle into place.
- For me, triple-pane glass in vinyl made the biggest impact on city noise, not the frame.
- Unless you’re in a super cold spot or want to squeeze every bit of efficiency, I’m not sure the fiberglass upcharge is worth it.
- Still kinda tempted by the look of fiberglass, but my wallet says otherwise...
I’ve pulled out a ton of old wood windows from houses built in the ‘40s and ‘50s, and honestly, I get where you’re coming from on the price. Fiberglass looks sharp and feels solid, but when folks see the quote, most go vinyl—especially if the frames are already a mess. Vinyl’s just easier to flex into place if things aren’t square anymore.
Noise-wise, I’ve only seen real improvement when people upgrade to thicker or triple-pane glass, not so much the frame material. The only time I really push fiberglass is for folks in harsh climates or if they’re dead set on a certain look. Otherwise, it’s hard to justify the extra spend.
Ever notice that some of those old frames are so out of whack, even fiberglass can be a pain to fit? Vinyl gives you more wiggle room for weird openings. Just my two cents from being knee-deep in window installs over the years...
I get what you’re saying about vinyl being easier to work with, but I’ve had a different experience with fiberglass holding up better over time, especially in places with wild temperature swings. I swapped out a few windows in my own place—some openings were definitely wonky, but after the install, the fiberglass stayed tight and didn’t warp like the vinyl ones I put in the basement a few years back. Yeah, it’s more upfront, but I haven’t had to mess with drafts or sticky sashes since. Sometimes that extra spend pays off down the road... just depends how long you plan to stick around.
I hear you on fiberglass holding up better in theory, but honestly, I haven’t seen vinyl fail as badly as folks say—at least not with the newer stuff. My place gets pretty wild winters, and the vinyl windows I put in five years ago are still square and slide fine. I do think fiberglass is tougher, but for me, the install was way more of a hassle—those frames are less forgiving if your opening isn’t dead-on. Sometimes I wonder if the extra rigidity is more trouble than it’s worth unless you’re planning to stay for decades.
That’s exactly what tripped me up—fiberglass frames just don’t have any give, so if your opening isn’t plumb or square, you’re in for a headache. I had to shim way more than with vinyl. Out of curiosity, did you notice any difference in energy bills after switching to vinyl? I’m always trying to weigh performance vs. hassle.
Yeah, that’s the classic fiberglass headache—those frames are just stubborn. I’ve fought with more than one crooked opening, and let’s just say my shims have seen things. Vinyl is way more forgiving if your house has “character” (aka nothing is level).
About the energy bills, funny you ask. I swapped out a bunch of old aluminum sliders for vinyl a couple years ago and actually did see a drop, but not the dramatic kind the brochures promise. Maybe 10-15% better, but it’s hard to tell with how wild gas prices have gotten. The real difference for me was in drafts—vinyl sealed up way tighter, so the living room didn’t feel like a wind tunnel anymore.
I do miss the look of fiberglass, though. It’s a pain to install but it holds up like a champ and doesn’t get as chalky as vinyl after a few summers. Still, if you value your sanity during install, vinyl’s the way to go... unless you’re a glutton for punishment or love a good puzzle.
