I've had vinyl windows in my off-grid cabin for about four years now, and honestly, they're starting to look a bit rough. The sun exposure seems to be making them brittle and faded faster than I expected. A friend of mine swears by fiberglass, says they hold up way better long-term, especially with temperature swings and harsh weather. I'm thinking of switching over...anyone else notice fiberglass windows lasting longer?
I've been wondering about this too. My vinyl windows are only two years old, but they're already looking faded and kinda warped from the heat. Fiberglass sounds promising, but is it really worth the extra cost? Curious if anyone's had them longer term...
Vinyl windows warping after just two years...that's rough. I've seen it happen plenty, especially in areas with intense sun exposure. Fiberglass is definitely sturdier—less expansion and contraction from temperature swings, so less warping overall. Installed some fiberglass windows about seven years ago for a client living off-grid in Arizona, and they're still holding up nicely. Yeah, the upfront cost stings a bit, but long-term durability usually pays off. Might be worth biting the bullet now to save yourself headaches later...
Yeah, vinyl can be tricky in harsh climates. Had a buddy who built an off-grid cabin up in Colorado, and he went with vinyl initially to save some cash. Two winters later, he was kicking himself—warping, drafts, the whole nine yards. Switched over to fiberglass windows after that fiasco, and it's been smooth sailing ever since. Plus, fiberglass tends to have better insulation properties overall, so you're looking at improved energy efficiency too. Definitely hurts the wallet upfront, but if you're off-grid, every bit of energy savings counts. I'd say fiberglass is worth the investment if you can swing it...less hassle down the road and fewer chilly nights spent cursing at warped windows.

Vinyl windows definitely have their limitations, especially in harsher climates. The brittleness and fading you're seeing after just four years isn't unusual—UV exposure and temperature swings really do a number on vinyl. Fiberglass, on the other hand, tends to handle these conditions much better because it's dimensionally stable and doesn't expand or contract nearly as much. I've installed both types over the years, and fiberglass consistently holds up better long-term. It resists warping, cracking, and fading far longer than vinyl.
The previous poster's point about insulation is spot-on too. Fiberglass frames usually have better thermal performance, meaning fewer drafts and more consistent indoor temps. Sure, upfront costs are higher, but when you're off-grid, energy efficiency pays dividends pretty quickly. If you're already seeing issues at four years with vinyl, switching to fiberglass now could save you headaches (and money) down the line.
Glad to hear fiberglass worked out better for you—I had a similar experience. We went vinyl initially because the price was tempting, but after a few rough winters, the frames started looking pretty sad. Warping, discoloration, and drafts...you name it. Switched to fiberglass about three years ago, and it's been night and day. No more chilly breezes sneaking in around the edges, and the frames still look brand new.
I agree the upfront cost stings a bit, but honestly, the comfort and peace of mind are worth every penny. Plus, when you're off-grid, every bit of insulation counts. Fiberglass just seems to handle temperature swings and UV exposure way better. I haven't noticed any fading or brittleness yet, even with direct sun exposure on the south side of our place.
Anyway, don't beat yourself up too much about the vinyl—live and learn, right? Sounds like you're already on the right track now.
