The term "tempered glass" might sound familiar if you've ever looked for protective screens for your smartphone, observed storefronts, or checked the specification of car windshields. But what exactly is tempered glass? How is it made, and why is it essential for architecture and construction? Let’s understand.
Tempered glass, also known as toughened glass, is a type of safety glass that undergoes specific treatments to enhance its strength and durability. During tempering, the glass is heated to extremely high temperatures and then rapidly cooled making it significantly stronger than regular glass.
But what does this mean for building construction and design? It means peace of mind! Tempered glass is significantly resistant to impact, and can resist high temperatures up to 250°C. In the unlikely event of breakage, it shatters into small, blunt pieces that are far less likely to cause any injury.
The benefits of using tempered glass are numerous. Tempered Glass is designed to withstand impact and high temperatures, making it ideal for a wide range of applications where strength and thermal resistance are critical such as curtain walls, railings, skylights, and table tops to name a few. The high temperature-resistant property of Tempered glass makes it a good choice for applications near heat sources such as kitchen backsplash and over-counter shutters as well.
Not just regular clear glass but frosted, solar control and even tinted glass can be tempered to enhance their durability. Toughened or tempered glass can be treated with a lacquered coating to create toughened lacquered glass (Saint-Gobain Colormaxx Dura) which can be a great choice for high-traffic areas like passageways and elevators and high-temperature exposure environments such as kitchen backsplashes as well. Laminated tempered glass combines layers of tempered glass with a PVB interlayer which ensures shatter resistance for added safety.

What is the difference between toughened and tempered glass?
Toughened glass and tempered glass refer to the same type of glass. Both terms describe glass that has been heat-treated to increase its strength and safety.
Is tempered glass good for the bathroom?
Yes, tempered glass is ideal for bathrooms due to its strength and high temperature resistance. Glass, in general, is moisture-resistant.
What is the difference between tempered glass and regular glass?
Tempered glass is significantly stronger than regular glass due to a treatment process that involves heating the glass to extremely high temperatures and then rapidly cooling it. Also, in the unlikely event of breakage, toughened or tempered glass shatters into small, blunt pieces instead of sharp shards averting the risk of injury.
How to tell if the glass is tempered?
Look for an etched Saint-Gobain logo and the toughening partner logo to ensure original product and quality.
Can tempered glass be cut?
No, glass cannot be cut or drilled upon after it has been tempered. Any cutting, shaping or drilling must be done before the tempering process.
