PITTSBURGH, US: PPG Industries’ flat glass business announced that it can now manufacture heat-strengthened glass in thicknesses of less than 3 millimetre, 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 millimetre 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.

Heat-strengthened thin glass also gives solar manufacturers the opportunity to cut downstream costs. For instance, manufacturers may reduce material costs for solar modules by using glass-on-glass module designs that eliminate the need for, and expense associated with, traditional protective plastic or polyvinyl fluoride (PVF) backing.

When incorporated into solar modules, heat-strengthened thin glass permits more sunlight to reach the active layer, which enhances the conversion of sunlight into energy and increases power output. With 2-millimetre SOLARPHIRE(R) glass, solar transmittance improves by 0.3 per cent compared to 3.2-millimetre glass and by 0.5 per cent compared to 4-millimetre glass.

PPG can produce Solarphire PV, Solarphire AR/2XAR and Solarphire NaB glasses as thin as 2 millimetre. Critical components made with heat-strengthened, thin-glass versions of these products for photovoltaic (PV), CPV and CSP designs have the potential to deliver unprecedented performance to the solar industry.
