Noise reduction for windows

I installed cityproof when I lived next to a playground and a garden. They recommend different types of treatments depending upon the type of noise. Everything they did was perfect . They also make something for the a/c.

There is not one solution to this. I spent months looking into this. There are a lot of schools of thought, which vary significantly depending upon what you can and are willing to do. Window inserts from the folks mentioned above certainly work. We replaced all of our massive street facing (second floor) east village windows with laminated, multi-pane, tilt and turn windows, and the noise difference is fabulous. Depends on what you can do. And from a physics standpoint if you have a lot of noise you will do better with layered windows.

NYC sport, Who made the Windows? Skyline? Thanks.

Initially, we were going to go with Beiber, which are lovely, but after a strange series of price changes that I could not figure out was caused my contractor or the vendor, we went elsewhere. The Bieber windows were very nice, but for 15 windows (large, in the range of 3-4 feet by 7 feet) the pricing kept changing by bizarre amounts, and in all events was substantial. We instead installed Marvin Ultimate laminated, aluminum clad tilt and turn windows. Basically, we installed the Miami-Dade hurricane-resistant models, which provides great noise resistance, and no criminal could break the window with a sledge hammer. Definitely not cheap, but we smile every time we close the window in summer time -- when you pull the window closed, there is near silence (and dispensing with double hung windows also helps a lot). As an aside, the aluminum window options, which I think is al Skyline does, are cold.

If this is an option, it works well. But for others the window insert does a great job of knocking down sound. The problem is having room for it, the looks, and it is a bear to clean. I have been there too.

Thanks. I installed the Marvin window with laminated glass at the back of apt. My windows are about 4x9 in size but fewer in number. They are already double paned but old. Will keep Marvin in mind when I replace. Thank you.

Are Bieber or Marvin able to keep the look of old pre-war single-hung windows?
