Soundproof Window Inserts

These soundproof window inserts reduce outside noise by at least 50% when placed over operable single-pane windows. The Acoustic Grade does an even better job, reducing noise by roughly 70%. (Double-pane windows must use the Acoustic Grade.)

Inserts are easy to install and remove and not only block outside noise, but also prevent inside noise from bothering your neighbors.
