Indow window inserts are easy to install and remove. The inserts are composed of custom cut pieces of acrylic glazing edged with our patented Compression Tube. The secret? We laser measure the inside of your window frames to get the exact shape so that we can make your inserts fit just right. That’s important because most window frames are significantly out of square.

Indow window inserts install as easy as 1 – 2 – 3 and they are effortless to remove! The inserts are composed of custom cut pieces of acrylic glazing edged with our patented Compression Tube. The secret? We laser measure the inside of your window frames to get the exact shape, so that we can custom make your inserts to be the exact right size and shape. That’s important because most window frames are significantly out of square.
Indow window inserts seal out harsh weather and keep the comfort inside by eliminating drafts and hot air seepage. They also cut heating and cooling bills by 20%* and reduce the noise coming through your windows by 50 to 70%.**
SEAL OUT DRAFTS & HEAT
Using flexible compression tubing
The tight seal between the Compression Tube and your window frame provides exceptional performance, keeping at bay cold drafts (or mitigating heat gain during the summer). Indow storm window inserts provide superior comfort no matter the weather or temperature outside.
HUSH THE NOISE
50-70% Decrease in sound penetration
Hush noise so you can sleep and live comfortably. When placed over operable single-pane windows, Standard Grade inserts dampen noise by up to 10dBA, which equates to 50% noise reduction. Acoustic Gradeinserts reduce noise through operable single-pane windows by up to 18.9 dBA, equivalent to a 70%+ reduction. 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.
SAVE ENERGY & MONEY
Reduce energy use by 20%
A U.S. Department of Energy study found that installing Indow inserts led to a more than 20% reduction in heating, ventilating and air-conditioning use in a Seattle home.
A separate study by Portland State University’s Green Building Research Laboratory found similar results. Comparing gas usage before and after installing Indow inserts in four Portland-area homes, the laboratory found heating-energy costs were reduced by an average of 19%.
FEEL THE THERMAL PERFORMANCE
Indow window inserts have 94% of the insulation of standard double-pane windows. The surface of an acrylic Indow insert is much warmer than the surface of a pane of glass, so you’ll feel warmer even if the air temperature in both cases is the same.
