How Our Inserts Work

Indow window inserts use our patented Compression Tube to press inside your window frame to seal out noise and drafts. Our Standard Grade inserts block sound by 50% and our Acoustic Grade inserts block more than 70% when placed over operable single-pane windows. When placed over operable double-panes, Acoustic Grade inserts reduce noise by up to 12 dBA – that’s more than a 50% reduction in noise and an STC rating of 42 to 45.

*We want to ensure our inserts help solve your noise problem. Overall noise reduction depends on the amount of noise coming through your walls, ceilings, floors, doors, and existing windows. Noise reduction will be less when placed over double-pane windows. Read our full Noise Reduction Sheet to learn more.

Indow Creates a Sanctuary from Noise

We care about creating shelters from sound in homes because we know what chronic exposure to noise can lead to: stress, heart disease, and poor cognitive performance. Providing a solution that works with existing windows puts less material in landfills – that’s part of our sustainable mission.

Customer Testimonials
Indow Sleep Panels

Indow offers a Sleep Panel to provide 100% light blocking in addition to noise reduction.

Dr. Lewis J. Kass, M.D., pediatric sleep specialist says, “The best environment [for sleep] is cool, dark, and quiet.”

Blackout shades and curtains often don’t seal out the light completely. You know those annoying slivers of light around your windows? 100% blackout means less waking up in the middle of naps and an easier time going back to sleep.
