TOUGHENED GLASS
Le-Gardien’s
principal in
Thailand processes both heat-strengthened and fully tempered glass using the computerised
Tamglass (USA) furnace. Our principal is the only company in this region who is capable of
tempering maximum size of 7500 x 2438 mm for 12mm, 15mm & 19mm glass thickness.
The process of toughened glass is by heating normal glass till it reaches the softening thermal level and then quenching it by a uniform blast of air.
Once toughened, the glass cannot be cut, notched, drilled or ground.
Characteristics
Heat-Strengthened Glass |
Fully-Tempered Glass |
| About two times stronger than annealed glass of equal thickness | About four times stronger than annealed glass of equal thickness |
| Greater resistance to thermal loads than annealed glass | Greater resistance to thermally induced stress than heat strengthened or annealed glass |
| Typically breaks into larger pieces | Typically breaks into classic tiny piece pattern |
| Less prone to spontaneous breakage than tempered glass | Occasionally can experience spontaneous breakage due to nickel sulfide inclusion |
