“Similar, but superior to double-paned glass windows.”

*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.

Even if your home has historic windows that are no longer square, our laser measured inserts are custom made to fit and only take in 3-4 weeks to deliver. Indow inserts cost only $24-$36 a square foot and have a Limited Lifetime Warranty.
