Toughened
Toughened glass is a type of safety glass that undergoes a toughening process in a furnace at a temperature around 600 degrees.
Not only is toughened glass almost five times stronger than annealed glass, it also breaks in a much safer manner during an impact.
Under the AS2208 fragmentation test, toughened glass must shatter into small particles to meet Grade A safety glass requirements. With 4mm toughened glass, for example, the number of particles must be at least 30 per 250mm square glass sample.
Ramarex always uses toughened glass in all windows and doors as standard sourced, from accredited Australian glass manufacturers and suppliers. The thermal performance of toughened glass is the same that of annealed glass.
