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.
EASY STORM WINDOW INSERTS
Simple yet highly effective
Indow storm window inserts are made out of acrylic glazing and edged with our patented Compression Tube. The tubing compresses when pressed inside your window, holding the insert securely in place while sealing out cold drafts and hot air. The tight custom seal delivers superior performance.
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 Grade inserts 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%.
