The Cityproof Difference

Quality soundproofing involves sealing out the annoying exterior noises. To achieve the best seal, custom measurements of every window and manufacturing to tight tolerances is required. The seal, and therefore the noise reduction, that you'll receive from an all-custom process like Cityproof's is unique and unequaled. Cityproof is also the only soundproof window manufacturer using a unique stainless steel perimeter tracking system. Stainless steel provides the highest durability and the tightest seal available in the market.

Cityproof has been manufacturing and installing soundproof windows since 1960 and has installed over 35,000 custom made City Windows in over 3,300 landmark and non-landmark buildings in the greater New York area. Our master craftsmanship and commitment to customer service has provided both referrals and repeat customers.
