Been dealing with some pretty annoying street noise lately (thanks, new construction down the block 🙄), and I'm looking into those window insert things that help dampen sound. Did a bit of googling and seems like there's two main types—acrylic and glass. Acrylic seems lighter, easier to handle, and cheaper, but I've read a few comments saying glass is better at actually blocking noise. But then again, glass is heavier and pricier, and I'm not exactly handy enough to confidently install something heavy without worrying I'll drop it or something, lol.
Has anyone here tried either type? Curious if the difference in noise reduction between acrylic and glass is really noticeable or if it's just marketing hype. Also wondering if acrylic scratches easily or yellows over time...you know how some plastics get kinda gross after a while. Would appreciate hearing your experiences before I pull the trigger on this.
I've been wondering about this too, actually. A friend of mine installed acrylic inserts last year because she lives near a busy intersection, and she swears by them. She did mention that they can scratch if you're not careful cleaning them, but no yellowing yet (though it's only been about a year). Noise-wise, she said it made a noticeable difference, but I haven't personally compared it to glass.
One thing I'm curious about though—does thickness matter much for noise reduction? Like, would thicker acrylic panels maybe match thinner glass ones in terms of sound blocking? If anyone's experimented with different thicknesses, I'd love to hear how that worked out. Seems like that might be a good compromise between weight and effectiveness...
"One thing I'm curious about though—does thickness matter much for noise reduction?"
Thickness definitely matters. When we redid our bedroom windows, we tried thinner acrylic first—helped a bit, but still heard traffic clearly. Switched to thicker acrylic (about 1/4 inch), and it was noticeably quieter. Not glass-level silence, but pretty close and way lighter to handle.
Thickness is definitely a factor, but spacing matters too. When we added acrylic panels to our living room windows, we left about a 2-inch gap between the original glass and the acrylic—made a huge difference. Traffic noise dropped significantly...almost as good as double glazing.
Agree with the spacing comment above—it's key. I've installed both types for clients, and honestly, acrylic works fine if you're careful not to scratch it during cleaning. Glass is slightly better sound-wise, but the difference isn't huge enough to justify the extra hassle and cost IMO.
I've had acrylic inserts for a few years now, and honestly, they're holding up pretty well. I mean, I'm not exactly gentle when cleaning (my spouse says I clean windows like I'm scrubbing burnt pans), but still no major scratches yet. Glass might be slightly better for noise, sure, but unless you're living next to a freeway or something, acrylic does the job just fine. Plus, saving money is always nice—more cash left over for important stuff...like snacks.
Interesting take, but I'm still wondering if acrylic really holds up long-term. I've heard some people say it can yellow or get cloudy after a while, especially if your windows get a lot of direct sunlight. Have you noticed anything like that? Glass might be pricier upfront, but if it stays clear and effective longer, maybe it's worth the extra cash in the long run... snacks aside, of course.
