About Whisper Windows
Whisper Windows is a New York–based window soundproofing company specializing in custom interior window inserts for apartments, homes, and buildings in the NYC area.
We help reduce traffic noise, street noise, vibration, drafts, and temperature loss—without replacing existing windows or requiring construction. Our solutions are renter-friendly, fully reversible, and professionally installed.
What We Do
Whisper Windows designs and installs clear interior window inserts that work with your existing windows to significantly improve noise reduction and comfort.
All installations are custom-fit and handled by our team from measurement through installation.
Unlike window replacement, our inserts:
- ✓Add a second interior layer
- ✓Create a larger air gap
- ✓Block low-frequency city noise more effectively
- ✓Avoid disruption, permits, and permanent changes
