Soundproof Interior Windows in New York & Metro NY Tri-State

The #1 way noise penetrates apartments, homes and offices is through exterior windows. With Cityproof, there’s no need to replace or modify windows! Our interior Citiwindows® can be more economical and provide more noise reduction than replacing windows.

How our advanced soundproofing system works:

Our custom-designed and manufactured Citiwindows are installed on the inside and work in conjunction with your existing exterior windows to create a buffer zone of airspace that seals out loud city noises.

Internal Installation

The Citiwindow is an internal window installed on the inside of an existing window. The exterior window remains as is.

Sound Buffer Zone

The airspace created between the exterior window and the Citiwindow acts as a sound buffer zone, also stopping drafts & dirt from outside.

A Perfect Seal

Our unique tracking systems provides a perfect window seal. And a perfect window seal means up to 95% less noise for you!

What you'll get with Cityproof Citiwindows:

Up to 95% noise reduction
99% draft and dirt elimination
Up to 30% energy savings per year
No structural changes to existing windows and no obstruction of views

The windows were installed yesterday, and it could not have gone better. The team arrived right on time and did a fantastic job. They were efficient, neat, precise, and paid attention to every detail.

The windows look fantastic. The bronze seems a little darker than I remembered, more black, but it works out even better. I am so glad I went with the clear glass and the full thickness. The problem noise is nearly gone (and we had a good test the same afternoon), and dad says he no longer feels any draft. Why did I wait so long? The glass is so clear you don’t know it’s there.

I’d recommend Cityproof to anyone who asks. Thank you, thank you, thank you!

I did want to take a moment to let you know what a terrific job your installers did. I was genuinely impressed with their efforts to get the installation exactly right. It is much appreciated.

Really great work. I built a home studio and needed good soundproofing. Cityproof delivered. Not only do the windows work beautifully (haven’t heard a sound from outside in the middle of NYC since they were installed), the installation crew could not have been more professional or focused on doing a perfect job. Highly recommend them.
