*Note, overall noise reduction performance depends on how much noise is coming through walls, ceilings, floor, and doors. The window noise reduction will be less when Indow inserts are placed over double-pane windows. We do not recommend Indow inserts for reducing noise coming through laminated glass windows, triple pane windows, or hurricane windows.

 
 
Indow is fully operational making window inserts that bring comfort and quiet to your home and work spaces. Our production team is using Clean Manufacturing principles we have developed to keep them safe. No one needs to enter your home to measure or install our inserts. We ship a self-service measure kit (sanitized between each use) and deliver the inserts to your door. Just pull the insert from the box and they are ready for installation. We look forward to serving you.
