Indow, the window insert company committed to providing comfort, quiet and savings while helping preserve the environment and historic buildings, delivers its Acoustic Grade window insert acrylic glaze, offering customers a high-quality window insert that provides unparalleled noise reduction. 

For operable single-pane windows, Indow Acoustic Grade reduces noise by 18.9 A-weighted decibels (dBA), which is the equivalent of a 70 percent reduction. The Indow Acoustic Grade reduces noise coming through a double-pane window by 10-12 dBA, the equivalent of a 50 percent reduction. 

Indow acoustic grade is also available in Commercial Grade, providing sound reduction and extra-abrasion resistance. The Indow Commercial Grade features an extra abrasion-resistant coating to provide additional protection against scratching that may occur during frequent cleaning or moving, without compromising on the transparency of the window. 

Indow manufactures and installs six grades of window inserts. Each is a custom-manufactured sheet of acrylic edged with the company’s patented compression tube. They require no track or magnetic system that can damage existing windows. 

The winner of numerous environmental and green building awards, Indow window inserts have reduced nearly 80,000 tons of CO2 emissions in the U.S. and Canada.
