CitiQuiet

What CitiQuiet does

CitiQuiet is a family-owned designer, manufacturer, and installer of soundproof window systems, founded in 1992 by Michael Lentin and headquartered in Long Island City, NY. The company's core product is a patented interior window insert, the CitiQuiet Soundproof Window System, which installs in front of existing windows without alteration and is engineered to block up to 95% of outside noise. The system combines laminated acoustic glass with a polyvinyl butyral (PVB) interlayer, varying glass thicknesses to prevent coincidence effect, wide air gaps of typically 4-5 inches between panes, and compression seals to eliminate flanking transmission. CitiQuiet holds a patent on this system and manufactures all units in a 100,000 square foot vertically integrated facility in Long Island, NY, with no subcontracted labor for installation.

The company serves both residential customers (primarily NYC apartment, condo, brownstone, and townhouse owners dealing with urban noise, plus home offices and nurseries) and commercial/institutional customers including offices, hotels, hospitals, schools, recording studios, and government buildings. CitiQuiet generates revenue through one-time sales of custom-manufactured windows bundled with measurement, manufacturing, and installation services; pricing is quote-based and not publicly disclosed. Distribution is hybrid: direct field sales (in-home consultations with on-the-spot quotes) and inside sales (phone and web quote requests) in NYC, plus an authorized dealer network in Los Angeles (Tashman Screens and Hardware), Chicago (Soundproof Chicago), and Philadelphia (Michael's Glass Company). High-profile projects include soundproofing installations at the U.S. Supreme Court, the MTA offices at 2 Broadway following 9/11, the federal building at 90 Church Street, Park Central Hotel, and multiple recording studios, demonstrating credibility in both residential and institutional markets. The business has been family-owned across three generations with no disclosed private equity or institutional funding, differentiating it from competitors in the broader home-improvement category.
