Using flexible compression tubing

The tight seal between the Compression Tube and your window frame provides exceptional performance, keeping at bay cold drafts (or heat during the summer). Indow storm window inserts provide superior comfort no matter the weather or temperature outside.

50-70% Decrease in sound penetration

Indow storm window inserts offer remarkable sound reduction. When placed over an operable single-pane window, Standard Indow window inserts dampen noise by up to 10dBA, which equates to a 50% noise reduction. Acoustic Grade inserts reduce noise by up to 18.9 dBA, equivalent to a 70%+ reduction. Hush the sounds of traffic, planes and early-morning garbage collection so you can sleep and live comfortably.

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%. carbon-footprint-legend





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.

** R Value measures the thermal resistance of a material and its effectiveness at keeping the outside out and the inside in.


Indow inserts + single-pane data provided through independent testing conducted by the US Department of Energy’s Pacific Northwest National Lab and Portland State University’s Green Building Research Lab. Actual performance will vary depending on condition of window.
