Soundproof Storm Windows
Indow window inserts are custom-made interior soundproof storm windows edged with our patented silicone compression tubing that simply press into the interior of a window frame, sealing out sound and drafts more effectively than traditional exterior storms. Our inserts install easily with no mounting bracket.
When placed over operable double-pane windows, Acoustic Grade inserts reduce noise by up to 12 dBA, equivalent to more than a 50% reduction in noise and an STC rating of 42 to 45.
*Overall noise reduction performance depends on how much noise is coming through walls, ceilings, floors, and doors. You can download an independent STC testing report here.
