City Windows

approx. 800$ for a small bedroom(we chose the cheapeat/thinnest glass because we needed it for isolation/air draft,not for noise reduction) we used cityproof,maybe you can find more info on their website.I think the thickest glass,for noise reduction was 100-200 more.

One of my neighbors just got a quote this week from one of these firms- It was around $1,400 per window for the model with a 90% noise reduction (the thicker glass, but I don't think this is the thickest). The window size for this quote was for a larger window- about 71 by 45.

Very helpful, thanks. In the context of a $4000-$5000 / month apartment, seems like a no-brainer.

If you a temporary fix, I got insulating-roomdarkening curtains from Target and they really helped reduce noise. They cost about $25 a pair at Target and almost $50 at Bed Bath & Beyond (I have a pair of each) and there's no difference between them.

Best of luck!

Also, if there's an in wall AC, it's about $500 to build a sound proof surround, to further dampen sound thru the City Windows companies. Apparently, if you don't also put a barrier around the AC, sound travels thru the large whole in the wall. (Some ACs are sound proof however, you may want to look into that too).

It takes approx 5 weeks for your windows to be built and installed. You will need to provide to City Windows the information for a certificate of insurance for the apartment owner and the building.

GL!
