I actually had an incredible response from CitiQuiet windows. They did my living room, bedroom and my daughter's bedroom. I went with the 90% noise protection windows. They arrived in 3 weeks and, I can't begin to tell you what a lifesaver they are. We all actually sleep, and even better when my out of town relatives come over they all remark how they don't even feel like they're in the city because of how quiet it is. Before, I used to get so much slack for living in the city and having my daughter grow up in a noisy city.
Seriously, if you've not a noise issue - call citiquiet windows, or visit their website:
