Street noise disrupting your home life?

You can have peace and quiet even when it’s loud outside. Reinforce your windows against noise penetration – without having to replace them. Indow window inserts just press inside your window frames to block 50 to 70% of the noise that’s bothering you.*

Unlike other solutions, Indow window inserts don’t require bolting anything to your window frames or walls. This makes them an excellent choice for renters or those with historic homes who want to keep their original windows intact while enjoying the benefits of soundproofing.

How Our Window Inserts Work

Indow window inserts use our patented Compression Tube to press inside your window frame and seal out noise. Our Standard Grade inserts block sound by 50% and our Acoustic Grade inserts block more than 70% when placed over operable single-pane windows. When placed over operable double-panes, Acoustic Grade inserts reduce noise by up to 12 dBA – that’s more than a 50% reduction in noise and an STC rating of 42 to 45.

What Our Customers Say

The following video contains real footage submitted by one of our customers. The sound has not been edited to demonstrate their perceived window noise reduction.


*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.
