Has anyone used this product for windows?

Anyone tried these? they range from $300-$500 per window but I only have one small window and I'd like to not block the light.


Thanks,

Dennis, I've not used those specific windows but the theory is good (up to where they recommend more than two panes) - it follows the same physics as wall construction. If you've read the "sticky" called "complete section", you know that the best efficiency of materials is accomplished by using only two centers of mass with only one air space - also that each mass center should be different, to avoid having both leaves with the same weak point.

Conventional double pane windows use the same weight glass in both leaves, plus the air gap is minimal for simpler installation. Neither of these practices is good for sound reduction.

Your best improvement would be using one window like the ones you linked in conjunction with an existing SINGLE paned window.

While you would see a slight improvement with a third window, it would NOT be worth the cost in 99% of situations.

Overall, I didn't find much to dissent on their site - that's kind of rare for me; the more I learn, the less I believe. Some sites are just plain ridiculous if you've spent more than a few hours with a good acoustics book.

You could probably build your own second window cheaper than their prices, but for one small window and simple installation you would probably be ahead to just go for it - if you also want the window to OPEN, I'd recommend it even more... Steve
