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 grade of Indow window inserts reduces outside noise by at least 50% when placed over an operable single-pane window. Our Acoustic Grade does an even better job, reducing noise by 70%.* (If you have double-pane windows, you must use Acoustic Grade for reducing noise.)

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