Yet at Tufwell Glass, we believe that glass should remain unbroken all year round! This is why we use toughened glass in many of our products.
Toughened, or tempered glass, is one of the most widely used glass products worldwide. It is created by passing standard annealed glass through a temperature and time-controlled oven which takes the glass temperature to near melting point. Its surface is then rapidly cooled whilst internally the glass remains hot. This process alters the physical properties of the glass and results in a product which can withstand higher pressures than ordinary glass.
The most important benefit of toughened glass is safety. Toughened glass is up to five times as strong as ordinary glass and can withstand greater impact or sudden changes in temperature. Its resilience makes it cost-effective and ideal for use in internal glass doors, glass shelves, glass tables and glass partitions; in fact, anywhere where shattered glass would pose a safety hazard. When ordinary glass breaks, it shatters into sharp slivers of glass which can cause personal injury. However, if toughened glass gets broken, it crumbles into small pebble-shaped pieces instead, which minimise the risk of harm.
Because toughened glass cannot be re-cut or pressed to shape once it has gone through the tempering process (to do so would cause the entire pane to crumble!), production must be extremely precise. At Tufwell Glass, we have our own dedicated glass-tempering facility and can provide toughened glass sheets up to 2400mm x 3600mm, in thicknesses between 6-19mm.
Although toughened glass has very occasionally been known to shatter spontaneously, such occurrences are extremely rare. Fortunately, the risk of shattering can be mitigated by experienced glass technicians, who are extremely capable in installing panes correctly and spotting nicked or chipped edges before they have a chance to develop into larger breaks. Any defects can then be put this right immediately.
Other internal defects within the glass such as nickel sulphide inclusions are almost impossible to spot with the naked eye. Yet at Tufwell Glass, we have a solution for this. Whilst still in the factory, all our panels are put through a special heat soak facility, which accelerates the expansion of any rogue nickel sulphide particles and enables any contaminated panes to be detected and eliminated before they make it onto site. So you can be assured that the toughened glass panes that we provide have been thoroughly tested and are of the utmost quality.
Overall, the advantages of toughened glass are manifold. By purchasing toughened glass from reputable glass specialists Tufwell Glass, you can rest safe in the knowledge that the glass has been well-tested for its strength and durability and will stand the test of time.
