As glazing specialists, K Glazing are proud to supply a number of specialist forms of glass for use in our windows, doors and conservatories. One of the most popular types of specialist glazing we supply and install is toughened glass.
What is toughened glass?
Toughened glass is simply what its name describes: glass that has been toughened by the tempering process.
A type of safety glass, toughened glass is created by thermal and chemical treatments thatincrease its strength compared with conventional glazing: known as ‘tempering’. The tempering process creates tension in the inner surface of the glass, and compression on the outer surface, making the overall glass much stronger. The different stresses inherent in the glass mean that if broken it crumbles into small chunks rather than into dangerously sharp shards. These smaller chunks present less of a safety hazard.
Thanks to its enhanced strength and safety properties, toughened glass is used in a variety of applications such as car windows, fridge trays, and shower doors: it’s even a component of bulletproof glass.
The history of toughened glass
Although toughened glass is a relatively recent invention, the effects of the ‘tempering’ process have been known for over 500 years. In the 17th century, Prince Rupert brought some glass objects known as ‘Dutch Tears’ or ‘Prince Rupert’s Drop’ to Britain from Holland. These were created by dripping molten glass into cold water. As the glass cooled, it created a long tadpole-shaped piece of glass which could withstand hammer blows on its larger end. These provoked much curiosity and scientific debate.
In 1874 Francois Barthelemy Alfred Royer de la Bastie perfected a way of creating toughened glass by tempering it in hot oil and grease which led to the development of the modern day tempering process.
The benefits of toughened glass
1. Improved security
Offering higher levels of security than standard double glazing, toughened glass can withstand the sustained impact and attack without shattering. This makes it perfect for use around homes where high security is important.
2. Better peace of mind about the protection of your home
Your peace of mind when it comes to the safety of your home and possessions should be paramount when you think about improving your home. That’s why investing in toughened glass is a good decision to make. You never know when a burglary or an accident may strike, so installing toughened glass can help to put your mind at rest when it comes to protecting your home and family from risk.
3. Less chance of splintering if broken
Even the most secure and strongest glazing types can break. The jagged shards of glass created when standard double glazing breaks can cause a safety hazard. This can be particularly dangerous if you have young children or pets. Thanks to the tempering process, toughened glass will not splinter when broken, instead crumbling into tiny blocks. These are not as sharp or as deadly as normal glass splinters.
