soundproofing with double glass non impact windows
« on: February 17, 2014, 05:19:24 PM »

I presently have single-pane windows. I live near the highway and when the wind heads my direction it gets noisy. I was wondering if replacing the windows with a good double non-impact window such as Home Depot's American Craftsman would make a significant difference in noise levels in the house.

If you solid noise reduction you must create the dead air space of 1"-3" like you would see on a commercial plane.
We use this system to achieve quality reductions.

I have to say that I've come to the conclusion that there is no such thing as soundproof windows. Maybe that's because I just lost out $1,800 on ones I recently purchased. Despite all of the great reviews and videos the windows I bought do not work and I can hear every noise as if the windows were not there at all. The owner was well aware of our problem and at first offered to take them back for a partial refund, and then changed his mind altogether. For whatever reason, and I do know I'm not the only one, the windows have absolutely no effect at all. If I can mention the company I will just so that other people don't suffer the same disappointments: or they go by

Like I said they didn't work at all for us and I'm left once again trying to figure out what works at keeping out loud music that a business near us blasts every summer. We're going to try to use various materials to make soundproofing curtains. Sealing them up with magnets to make a seal. Fingers crossed. For me personally unless I see for myself a window or window type system that really works I will not be spending money like that again.... not that I could afford to.  So be careful when buying windows because they do not work for everyone despite the claims.

We will definitely leave your post up so others can read of your bad experience. We see this happen quite often.
Understanding the key principle about soundproofing windows is what takes out the guess work.

Mass and dead air space dictate the reduction you see.

when doing soundproofing window systems it is important to create the greatest air gap 2" min or greater between to pieces of heavy glass or acrylic.
Think about it like a commercial airplane which is 2 pieces of 3/8" safety glass with a 2" dead air space... in recording studios it could be as much as 8" to 18" of dead air space and even then you will never achieve 100% soundproof.

How much of an air gap did you achieve?
and how thick of glass did they use?
and did they seal around the casing of the window and the frame?
