Excellent product, support, and very clear instructions. We look forward to installing these on all our windows.
You can have peace and quiet even when it's loud outside. Reinforce your windows against noise penetration – without having to replace them. Award winning Indow window inserts just press inside your window frames to block 50 – 70% of the noise* and save 20% on energy bills. See all Indow performance data.
We care about creating shelters from sound in homes because we know what chronic exposure to noise can lead to: stress, heart disease, poor cognitive performance. Providing a solution that works with existing windows puts less material in landfills – that's part of our sustainable mission.
Indow window inserts use our patented Compression Tube to press inside your window frame and seal out noise. 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.

I ordered the "acoustic grade inserts" for my bedroom to reduce road noise. They work exactly as advertised. Are they soundproofing? NO. Do they reduce noise to acceptable levels? YES. Compared to other solutions on the market (replacement windows, glass inserts etc) this is much more affordable. However, if you are looking for actual soundproofing, you need to spend more money and get something else. As a bonus, the inserts are tight fitting and have reduced drafts.
