Stone Panels, Inc.® Product Proves Testing Results in Real-World Conditions
DALLAS (September 2011) – Fairbanks, Alaska (just like everywhere else in the northern hemisphere) is saying goodbye to its warmest time of year as the summer months draw to a close and fall begins. Although the January temperature low of -37 degrees Fahrenheit may be outdone in the remaining months to come, we can say with confidence that the 2011 high of 88 degrees Fahrenheit in Fairbanks should be the hottest the area gets this year.

For the Fairbanks Courthouse and the StoneLite® stone panels with which it’s built, 2011 temperatures are real-world proof of results from StoneLite® product testing. Stone Panels, Inc.® has put its StoneLite® product through the most rigorous of product testing, including acid freeze-thaw testing. This testing gave building operators across Alaska (and around the world) the reassurance that their facade could withstand extreme temperatures in 2011.
As an example, one of the many testing methods conducted on the StoneLite® product was developed by Wiss Janney Elstner Associates Engineers. This test subjected marble, limestone, travertine and granite panels to an accelerated aging procedure of temperature cycling 100 times, from 170 degrees Fahrenheit to -10 degrees Fahrenheit. All the while, the stone face, bond line and honeycomb were submerged in a 4-pH sulfuric acid solution. Subsequently, the exposed and corresponding control samples were subjected to flexure loading, which put the stone and bond line in tension.
The testing resulted in zero bond failure and a flexure strength loss of only 13 percent. Compared to the alternative building material of dimensional stones, which lost 25 to 70 percent of their original strength in the testing, buildings built with StoneLite® know they have a better chance of surviving extreme temperatures than many of their counterparts which were built with dimensional stone.
