7 Advantages Of Tempered Glass

It's Safer
The biggest advantage of tempered glass over annealed or “ordinary” glass is that it was designed for safety. Unlike annealed glass, which breaks into large and dangerous shards, tempered glass disintegrates into small granular chunks that are relatively harmless.

It's Tougher
The thermal tempering process used to manufacture tempered glass makes it much stronger than ordinary glass. Tempered glass can stand up to strong winds, direct impact from blows and bumps, and minor explosions.

It's Heat-resistant
Tempered glass can resist temperatures of up to 470 degrees Fahrenheit. This property makes tempered glass ideal for use in kitchen appliances and in areas like the bathroom, where it will likely be in contact with the heat on a regular basis.

It's Crystal Clear
While the tempering process makes tempered glass super tough, it doesn't affect the clarity of the glass. Tempered glass is crystal clear and transparent, which makes it useful in windows, display cases, and glass doors.

It's versatile

Tempered glass can be used practically anywhere glass is needed. It makes for an attractive and sturdy frameless shower door, a fully transparent smartphone screen protector, and a seamless stovetop base

It doesn't scratch easily

The manufacturing process that makes tempered glass thermally tough also makes it scratch-resistant. This makes tempered glass an ideal material for glass doors, kitchen appliances, mobile screen protectors, and passenger vehicle windows.

It is available in various designs and patterns

Tempered glass can be clear, frosted, engraved, stained, and patterned. It's available in an array of patterns and designs to suit your needs.

Application of Tempered Glass

Windows

Tempered glass, or some form of safety glass, is recommended in commercial settings and under certain circumstances in residential settings, depending on the size of the window and its proximity to walking surfaces.

Doors

Any swinging, sliding, or bifold door should use tempered glass, regardless of size.

Wet Areas

Glass in wet areas like shower doors in bathrooms and doors and windows around swimming pools and saunas should be made of tempered glass due to the increased risk of falls.

Near Stairs

Building codes require that glass near or adjacent to stairs and glass used for stair rails should use some form of safety glass, like tempered glass. Steps with glass surfaces should also be made using some form of safety glass.

Understanding The Glass Tempering Process

Cutting and Shaping: The glass is first cut to the required size and shape. Any cutting, grinding, or other modifications must be done before the tempering process because once tempered, the glass cannot be altered without shattering.

Heating: The shaped glass is then heated in a tempering furnace to a temperature of approximately 620 to 650 degrees Celsius. This heating phase is crucial as it prepares the glass for the rapid cooling process that follows.

Rapid Cooling: After heating, the glass undergoes a process called quenching. During quenching, the glass is rapidly cooled by blasting it with air from all directions. This rapid cooling process causes the outer surface of the glass to cool and harden quickly, while the interior remains at a higher temperature. As the interior cools, it contracts, creating a balance of compression and tension that gives tempered glass its strength.

Quality Inspection: After the tempering process, the glass is inspected for quality. This includes checking for any imperfections or distortions that may have occurred during tempering. The glass is also tested to ensure it meets the required safety standards.

FAQ

Q: What is the difference between toughened and tempered glass?

A: 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.

Q: Is tempered glass good for the bathroom?

A: Yes, tempered glass is ideal for bathrooms due to its strength and high temperature resistance. Glass, in general, is moisture-resistant.

Q: What is the difference between tempered glass and regular glass?

A: 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.in the unlikely event of breakage, toughened or tempered glass shatters into small, blunt pieces instead of sharp shards averting the risk of injury.

Q: How to tell if the glass is tempered?

A: Look for an etched Saint-Gobain logo and the toughening partner logo to ensure original product and quality.
