Soundproof Windows Designed & Manufactured in New York City
Soundproof Windows Designed & Manufactured in New York City
Every Cityproof Citiwindow® pairs with your existing window to create an airtight sound buffer that seals out Long Island noise, drafts, and dust, providing superior comfort and peace for homes and offices across Long Island.
From Nassau County to the East End, Long Island homeowners know that peace and quiet can be hard to come by. Whether it’s the steady hum of the Long Island Expressway, the rush of traffic along Sunrise Highway or Jericho Turnpike, or even the roar of planes heading to JFK and LaGuardia, noise finds its way into homes through thin or aging windows.
Even in quieter suburban neighborhoods like Huntington, Garden City, or Smithtown, the intrusion of lawn equipment, barking dogs, and weekend construction can disrupt what should be a relaxing environment. Add to that Long Island’s coastal winds, dust, and fluctuating weather, and it’s no wonder so many homeowners are turning to Cityproof for a solution.
Cityproof has been providing soundproofing services since 1960 and has worked hard to become the trusted name it is today. Featured in the NY Times and rated the best by New York Magazine and The Franklin Report, Cityproof has installed over 50,000 windows in the tri-state area. Every Cityproof project includes the highest-quality materials and installation that eliminate noise (up to 95%), reduce dirt and drafts (up to 99%), and decrease energy costs (up to 30%).
When it comes to creating quieter, more comfortable homes across Long Island, no one matches Cityproof’s experience, craftsmanship, or results. For more than 60 years, we’ve helped homeowners from Nassau County to Suffolk County block out traffic, wind, and everyday suburban noise with precision-engineered soundproof window systems — all custom-built right here in New York.
The Cityproof Citiwindow is an internal window installed on the inside of an existing window. The exterior window remains as is.
The airspace created between the exterior window and the Citiwindow acts as a sound buffer zone, also stopping drafts & dirt.
Our unique tracking system provides a perfect window seal. And a perfect window seal means up to 95% less noise for you!
