PPG makes heat-strengthened 2-millimeter glass for solar applications

PPG Industries’ (NYSE:PPG) flat glass business announced that it can now manufacture heat-strengthened glass in thicknesses of less than 3 millimeters, which makes it among the first major glass manufacturers in North America to offer this capability.

PPG can produce heat-strengthened glass in thicknesses of 2, 2.5 and 2.7 millimeters with surface-compression strength that exceeds that of fully tempered glass (greater than 10,000 pounds per square inch), while achieving ASTM C1048 standards for flatness. The added strength gives thin glass used in various solar applications that require resistance to wind load, hail impact and other environmental hazards the ability to meet UL and IEC (International Electrotechnical Commission) standards as well, which may help solar-module and solar-mirror manufacturers in North America.
