Thinking about fiberglass windows for humid coastal weather

Good insights on vinyl windows—I had a similar experience. Installed vinyl about 6 years ago, also right by the ocean, and they've held up pretty well. Only issue I've noticed is some slight discoloration on the frames facing direct sun, but nothing major. Honestly, for the price difference compared to fiberglass, I'd still choose vinyl again.

Totally agree about insulation too. I spent ages researching windows only to realize later that my attic and door seals were letting in way more drafts than my old windows ever did...lesson learned the hard way.

Haha, been there myself. I upgraded to fiberglass windows about 4 years ago because I figured they'd hold up better against the salty air and humidity here on the coast. Honestly, they're solid—no discoloration or warping yet—but looking back, I'm not convinced they were worth the extra cash compared to vinyl. My neighbor's vinyl windows still look pretty decent after almost a decade, aside from some minor fading like you mentioned.

And yeah, insulation issues are sneaky. I remember obsessing over window specs and then discovering cold air pouring in from gaps around recessed lighting fixtures in my ceiling. Talk about frustrating... If anyone else is considering fiberglass purely for insulation, I'd say first double-check your attic, doors, and even electrical outlets. You might save yourself a chunk of change.

I feel this one big time. A couple years back, I got totally fixated on upgrading my windows to fiberglass because everyone said they'd hold up better in coastal humidity. And yeah, they're definitely sturdy and haven't shown any signs of warping yet, but honestly...I probably could've gotten away with vinyl and saved some cash.

The kicker for me was realizing afterward that my biggest energy leaks weren't even the windows. Turns out my garage door weatherstripping was practically nonexistent, and the attic hatch was basically a wind tunnel. Spent an afternoon sealing those up, and it made way more difference than the pricey windows ever did.

So yeah, fiberglass is great for durability, but if you're mostly chasing energy savings, I'd say look at the sneaky stuff first—attics, crawlspaces, outlets...all those little gaps add up fast. Learned that lesson the hard way too, haha.

Good points here, fiberglass definitely holds up well in harsh conditions, but I've seen plenty of vinyl windows last a good while too—even near the coast. Honestly, most window issues I've come across weren't the frame material itself but poor installation or cheap seals. Curious if anyone's noticed a big difference in noise reduction between fiberglass and vinyl? Seems like that's another factor people overlook until after they've spent the money...

Noise reduction's a good question, actually. In my experience, the frame material itself—fiberglass or vinyl—isn't usually the biggest factor in soundproofing. It's more about the glass package and how well the window seals up. Double-pane windows with laminated glass or different thicknesses between panes tend to do way more for noise reduction than just swapping fiberglass for vinyl.

That said, fiberglass frames can sometimes offer slightly better insulation and tighter seals over time because they expand and contract less than vinyl. But honestly, if noise is a big issue (like you're near a busy street or airport), I'd focus more on upgrading the glass itself rather than worrying too much about frame material.

Funny story: I had a client who insisted on fiberglass windows because he thought they'd block out his neighbor's barking dog better. After installation, he called me back complaining he could still hear Fido loud and clear. Turns out he'd gone cheap on the glass package...lesson learned there, haha.

Bottom line: don't overlook the glazing options—they're your real MVP when it comes to noise control.

Good points about the glass package, but I wouldn't totally dismiss frame material, especially in humid coastal areas. I've had vinyl windows installed at my place near the beach for about 6 years now, and honestly, they've started to warp a bit from the constant moisture and heat cycles. It's subtle, but enough to affect how tightly they seal—especially noticeable during storms or windy days.

A buddy of mine down the street went with fiberglass around the same time, and his frames still look brand new. No warping or gaps yet. So while I agree that glass is key for noise reduction, frame material can definitely matter when you're dealing with coastal humidity and temperature swings. Fiberglass might cost a bit more upfront, but from what I've seen, it holds up better long-term in these conditions.

Just something to consider if you're planning to stay put for a while...

Interesting experience with vinyl frames—I've heard similar stories, but I wonder if the quality or brand of vinyl makes a noticeable difference. Fiberglass does seem promising, but does anyone know how it compares to aluminum frames in coastal conditions? Aluminum's pretty common around here, and I've seen some hold up surprisingly well over the years, though corrosion can be an issue if they're not properly treated...

I've been wondering the same thing myself. A neighbor of mine switched from aluminum to fiberglass about five years ago, and honestly, the difference is pretty noticeable. His aluminum frames were decent but started showing corrosion spots after just a few years—even with regular maintenance. The fiberglass ones still look practically new, plus he swears they're better insulated. Makes sense, since fiberglass doesn't conduct heat like aluminum does... might be worth considering if energy efficiency matters to you.

Fiberglass definitely has an edge in coastal areas. Aluminum frames, even the higher-end ones, eventually succumb to corrosion from salt air—it's just chemistry. Fiberglass doesn't have that issue since it's non-metallic. If you're leaning towards fiberglass, make sure you get quality hardware (hinges, locks, etc.) that's rated for marine environments. Seen folks overlook that detail and end up with rusty hardware on perfectly good frames... kinda defeats the purpose.

Good points about hardware—seen that happen more than once. Another thing worth mentioning is installation. Fiberglass frames are great, but if they're not properly sealed and flashed during install, moisture can still creep in around the edges. Had a client last year who went fiberglass but skimped on installation quality... ended up with mold issues anyway. So yeah, fiberglass is solid for coastal humidity, just don't overlook the details.
