Can Low-E be tempered or heat strengthened?
A. All fabricators have been tempering the pyrolytics (hard coats) for many years. Because of its hard surface it requires no special handling or tempering furnace. Very few of the fabricators have mastered the art of tempering the soft coats. One supplier, PPG Industries, requires the fabricator to pass an audit of their operation before they will certify them to handle their high performance solar control glass, Solarban 60. We are proud to say that we were the second fabricator in the nation to become a Certified Fabricator.
