Been looking into replacing my windows lately, and I'm kinda stuck between double-glazed and triple-glazed options. I mean, I get that triple glazing is supposed to be better insulation-wise, but is it really worth the extra cost? I've heard people say it makes a noticeable difference in noise reduction too, but then again, others say the difference isn't all that big unless you live near a busy road or airport or something.
I live in a pretty average suburban neighborhood—no crazy traffic noise or anything, just typical street sounds and neighbors mowing lawns on weekends (ugh). Winters here get pretty chilly though, so energy efficiency is definitely something I'm thinking about. But I'm wondering if triple glazing is overkill for my situation...you know, like buying a Ferrari just to drive to the grocery store.
Anyone here have experience with both types? Did you notice a real difference in comfort or bills after upgrading to triple glazing, or was double glazing enough?
Triple glazing is nice, but honestly, in your situation, double glazing is probably enough. I upgraded from single to double glazing a few years back, and the difference in warmth and comfort was huge. My bills dropped noticeably too. A friend went triple-glazed, and while it's slightly quieter and warmer, the difference wasn't massive—especially considering the extra cost. Unless you're super sensitive to noise or live somewhere really cold, double glazing hits that sweet spot imo.
"Unless you're super sensitive to noise or live somewhere really cold, double glazing hits that sweet spot imo."
I'd mostly agree with this. I've installed both double and triple glazing myself, and honestly, the jump from single to double glazing is night and day—no question there. But triple glazing... well, it's a bit more nuanced. Technically speaking, triple glazing does offer slightly better insulation (lower U-values), but the real-world difference isn't always noticeable enough to justify the extra cost and hassle.
I helped a neighbor install triple glazing last winter, and while he swears by it, I couldn't really feel much difference compared to my own double-glazed windows. Sure, maybe a bit quieter if you're near a busy road, but unless you're living in a particularly harsh climate or have money burning a hole in your pocket, double glazing is probably the smarter choice. Just make sure you get quality frames and proper installation—those factors often matter more than adding another pane of glass.
