Gold Plus also offer Heat Strengthened glass.

Heat Strengthened glass is not a substitute for toughened glass in applications requiring a safety glazing material. However with a strength of approximately twice that of annealed glass, it is recommended for applications requiring extra strength and greater thermal resistance than annealed glass.

Unlike toughened glass, which in the unlikely event of fracturing, breaks into granules, Heat Strengthened glass simply cracks. It then tends to remain in the glazed position since the break cracks are few in number and their interlocking pattern limits relative movement.
