Heat Strengthened Non-Safety Glass is heat-treated by heating annealed glass to a temperature of approximately 1,150ºF (621°C), then rapidly cooling it. The glass is cooled by a carefully controlled airflow (also known as quenching), which uniformly cools all glass surfaces simultaneously. High airflow rates produce tempered glass and much lower airflow rates produce heat-strengthened glass.
Heat strengthened glass is two times stronger than annealed glass. This glass is used when safety codes are not an issue, but when a client needs a stronger product. We can fabricate heat-strengthened glass using any glass listed under glass types for fabrication. We can bend any thickness from 1/16 of an inch to one inch – to any radius or custom shape imaginable.
