They work well for insulating
They work well for insulating, not so much for noise.

Hi Shannon, thank you for taking the time to review. I am sorry to hear that the noise insulation did not work as well for you. A simple trick is to make sure the insert is installed as far away from the window as possible for the best noise performance (the larger the air pocket, the better insulated it will be). Please call us at any time if you would like other suggestions on maximizing the performance of your window inserts: 503-284-2260.
