Toughened glass is produced by heating annealed glass in a furnace to approximately 700°C and then rapidly blowing cool air onto both surfaces. This rapid cooling process is the key element in the physical changes in annealed glass that creates toughened glass.
Features and Applications
- Toughened safety glass is Grade A safety glass
- Up to 500% stronger than annealed glass and therefore is more resistant to thermal breakage and can withstand greater wind loads
- On breaking it fragments into many small harmless pieces unlike annealed glass
- Can be used within a temperature range of minus 70°C to plus 300°C (surface temperature should not exceed 250°C if other surface is lower than 0°C ambient)
- Recommended for door, side and low lights, frameless entries, balustrades, shower, bath screen panels and furniture
