Bending limits are generally set according to each manufacturer’s tolerance for risk.

Engineers on the team developed a Finite Element model of the full size IGUs (5’ x 10’) in order to predict where the greatest stresses would accumulate on the IGU in order to guide the placement of the sensors and gauges that would be attached to the testing panels.

The panels were instrumented with electronic strain gauges, LVDTs, and dial gauges to record all the movement of the glass. We had near-continuous data collection as the forklift was pulling the free corner of the panel out of plane.

Once we had the data from the testing of the full size panels we were able to recalibrate our Finite Element model to approximate the actual panel more closely and give us confidence we had an accurate modeling environment.

One lite of the small scale IGU was epoxied into the steel frame and the second lite was able to be distorted with a collection of set screws.
A total of 24 small scale panels were built and exposed to weatherization testing. Six panels served as a control group with no distortions applied. Another 6 panels were distorted to the equivalent of 4” out of plane deflection in the full size panels. Another set of 6 were distorted to the equivalent of 8” of deflection and the final 6 were distorted to the equivalent of 12” of deflection.

The weatherization testing of the 24 small scale panels was conducted in 3 phases over a total of 15 weeks. First, the panels were exposed to 2 weeks of high humidity. Next they went through 9 weeks of 6-hour cycling that exposed the panels to temperature extremes ranging from -20 degrees F to 140 degrees F, as well as exposure to ultraviolet light and mist sprays. Finally, the panels were exposed to another 4 weeks of high humidity At each point in the testing process the panels were checked for frost point temperatures and Argon retention, indicators of whether or not the airspace seal had been broken.
