About Us

Indow window inserts act as interior storm windows, pressing into the inside of existing windows to increase efficiency and reduce noise. 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.

How They Meet Our Criteria

  • Significant Substitution Advantage - Energy conservation, Repair services, Used/salvaged
