Why Soundproof Window Inserts?

Struggling with outside noise from neighbors, construction or traffic? We get it. Here’s a simple, easy-to-install window noise reduction solution. Just press Indow inserts into your window frames – with no mounting bracket – and be amazed at the quiet you enjoy. You’ll sleep better, feel better and enjoy your space more. Noise reducing windows have never been so easy.

The Best Way of Soundproofing a Window

Our acrylic glazing edged in our patented silicone compression tubing creates a tight seal and dead air space between the insert and your window. Anywhere air gets in, noise can too. To keep the noise outside, we ensure a precise, snug fit by custom making each acoustic window insert using our laser measuring system.

Unlike other solutions, such as storm windows, Indow window inserts don’t require bolting anything to your window frames or walls. This makes them an excellent choice for renters or those with historic homes who want to keep their original windows intact while enjoying the benefits of window soundproofing.

The Benefits of Indow Window Inserts:

Every Indow insert grade reduces outside noise by at least 50 percent when placed over operable single-pane windows. Our Acoustic Grade does a superior job, reducing noise by 70 percent.* If you have double-pane windows, Acoustic Grade is the only option for reducing noise.

Our Acoustic Grade inserts have extra-thick acrylic at nominal ¼“ (Standard Grade is nominal ⅛”) and block 70 percent of noise coming through operable single-pane windows, and 50 percent through double-panes. They’re easy to install or remove and not only block outside noise, but also prevent inside noise from bothering neighbors.

Customer Stories
indow window noise solution testimonial - acoustic window inserts
“After moving in, we realized just how busy the street was because it was so noisy we could not sleep at all. Neither could our infant,” said Maggie in Portland. The inserts “came on time and were installed so easily, I couldn’t believe it! The difference in sound was unbelievable.”

Data Driven Results

*Note, overall noise reduction performance depends on how much noise is coming through walls, ceilings, floor, and doors. The window noise reduction will be less when Indow inserts are placed over double-pane windows. We do not recommend Indow inserts for reducing noise coming through laminated glass windows, triple-pane windows or hurricane windows.
