Storm Window Inserts That Last

Our storm window inserts aren’t windows. They aren’t exterior storms or magnetic interior storm windows. Instead, they are custom-designed inserts that simply press into the interior of your existing window frames, with no hardware or mounting brackets required. This means they make your original windows perform like new, transforming them to meet your needs without the hefty cost of replacement windows.

Durable. Custom-made in the U.S. Easy to install. These are just a few of the many benefits our inserts offer. Our acrylic window inserts are edged with a soft silicone compression tubing that creates a tight seal. Laser measuring ensures they fit precisely and stay securely in place. Enjoy all the benefits of new windows, but with a simpler, custom-made solution!

Have Soundproofing Needs?

Are you struggling with outside noise from traffic or neighbors?  Here’s the simple, easy-to-install window noise reduction solution. Just press Indow inserts into your window frames – with no mounting bracket – and be amazed at the quiet you enjoy. You’ll sleep better, feel better and enjoy your space more. Noise reducing windows have never been so easy.


Indow inserts are the best way of Soundproofing your Windows

Indow's acrylic glazing edged in a patented silicone compression tubing that creates a tight seal and dead air space between the insert and your window. Anywhere air gets in, noise can too. To keep the noise outside, we ensure a precise, snug fit by custom making each acoustic window insert using our laser measuring system.

Want to know what it’s like living with noise-cancelling windows? Scott Sidler is a national blogger who tested out our inserts in his studio:

How much sound reduction can I expect?

Every grade of Indow window inserts reduces outside noise by at least 50% when placed over an operable single-pane window. The Acoustic Grade does an even better job, reducing noise by 70%.* (If you have double-pane windows, you must use Acoustic Grade for reducing noise.) They’re easy to install or remove and not only block outside noise, but also prevent inside noise from bothering your neighbors.
