Advanced Energy Panels triple the insulation value of a conventional window, improving the U-factor from .91 to .31 (see details at left about “What is U-factor?”).


One large, 48″ x 48″ single-glazed window versus the same window with the addition of Advanced Energy Panels.

Impact on Consumer:

On a 0°F day outside, with a 70°F house temperature, the inside surface of a single-glazed window will have a temperature of only 17.3°F; but with Advanced Energy Panels installed, the inside surface increases to 56.1°F

Scope of Project

ETC Laboratories was contracted by Advanced Energy Panels to perform air leakage tests on their product which was mounted to the interior of an existing window product. The purpose was to measure the effective air leakage reduction of the existing window product with the Energy Panel applied to the interior. The test method employed was ASTM E283 with all air leakages performed at a differential test pressure of 1.57 psf (25 mph). The primary window that the Energy Panel was applied to from the interior was a wood casement window.

Self Ignition Temperature, ASTM-D-1929, is 660°F
Rate of Burning, ASTM-D-635; Average Time of Burning is 5 seconds; Average Extent of Burning is 1.36 inches.
Smoke Density, ASTM-D-2843 is 36.9%.


The glazing film used in Advanced Energy Panels, which is a very thin, clear, heat-shrink polyolefin.

Impact on Consumer:

For all practical circumstances, Advanced Energy Panel film is not a smoke or fire hazard. It is so thin and light that in a fire it basically just shrivels up.

Would you drop a 14-pound bowling ball on a glass window? Of course not!  Not even if the window was made of Plexiglas or other tough material.

But we can’t resist a challenge, so we dropped the ball on our Advanced Energy Panels from a height of six feet. Result? The glazing films stretched, rebounded and showed hardly a trace of the impact. (But our tester’s bowling score is still dismal.)


Next, we played hardball. Flinging a baseball at the Advanced Energy Panel resulted in a rapid bounce back. Even at the local batting cage, with the pitching machine cranked up to 60 mph, the Advanced Energy Panels survived. Our conventional glass window did not.


Freeze frame from video of 60 mph baseball. Ball is shown deflecting the normally taut Advanced Energy Panel film from left to right about 4″. An instant later, it rebounded, leaving the film without a scratch.
