Understanding the Durability of Toughened Glass

Toughened glass, often chosen for its superior strength and safety features, plays a crucial role in various applications ranging from architectural designs like balustrades and shower screens to functional pieces like partitions and cabinets. This guide delves into the robust nature of toughened glass, exploring its manufacturing, safety benefits, longevity, and maintenance requirements.

What is Toughened Glass?

Toughened glass, also known as tempered glass, is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. The process makes it much tougher than standard glass and changes how it breaks, which is essential for its safety characteristics. Here’s a deeper look into its manufacturing process and how it differs from regular glass:

The Detailed Manufacturing Process of Toughened Glass

Toughened glass is made through a process of extreme heating and rapid cooling. Here’s how it happens:

  1. Heating: The glass is first cut to size and then heated to over 600 degrees Celsius, making it soft and malleable.
  2. Rapid Cooling: After reaching high temperatures, the glass is rapidly cooled with jets of cold air in the tempering furnace. This process, called quenching, cools the outer surfaces much quicker than the centre and sets up stress patterns within the glass.
  3. Stress Creation: The rapid cooling puts the surfaces and edges of the glass into compression and the inner part into tension. This stress pattern makes the glass much stronger and if broken, causes it to crumble into small granular chunks instead of jagged shards.

Key Differences Between Toughened Glass and Regular Glass

The main differences between toughened glass and regular glass lie in their strength, safety features, and manufacturing process:

Strength and Durability of toughened glass:

Toughened glass is up to five times stronger than regular glass due to the stresses created during the quenching process in its manufacturing. This increased strength makes it ideal for use in high-stress, high-traffic areas where safety is paramount.

Safety Features:

Unlike regular glass, which shatters into sharp shards that can cause serious injuries, toughened glass breaks into small, blunt pieces that are far less likely to cause injury. This characteristic makes it an essential material for many safety applications.

Thermal Resistance:

Toughened glass can withstand higher temperatures and sudden changes in temperature. This property is particularly beneficial for applications like glass doors and facades that experience significant temperature variations.

Cost and Manufacturing:

Manufacturing toughened glass is more intensive and costly due to the additional processing required. However, the benefits of durability and safety offset the initial higher cost.

These properties highlight why toughened glass is preferred in environments where safety and durability are required, setting it apart from regular glass. Whether it’s used for glass balustrades, Juliet balconies, kitchen splashbacks, table tops, or shower screens, toughened glass provides a robust, safe, and reliable option.

Is Toughened Glass Really Safe?

Toughened glass is renowned for its safety characteristics, making it a preferred material in high-risk areas. Key safety benefits include:

  • Enhanced impact resistance which prevents breakage under force.
  • Safety in breakage, as it shatters into small, less harmful pieces.
  • Heat resistance which makes it ideal for high-temperature environments.
  • The ability to withstand rapid temperature changes, reducing the risk of thermal breakage.

How Long Does Toughened Glass Last?

The longevity of toughened glass is one of its standout features. Under normal conditions, toughened glass can last for many years without losing its integrity or appearance. Factors influencing its lifespan include:

  • Environmental conditions such as exposure to harsh weather.
  • Frequency and quality of maintenance.
  • The level of physical stress it is subjected to in its application.

How Do You Maintain Toughened Glass?

Maintaining toughened glass is straightforward but crucial for preserving its clarity and durability. A proper maintenance routine ensures your glass remains in prime condition for a longer period. Maintenance tips include:

  • Regular cleaning with suitable glass cleaning agents to avoid the buildup of stains and contaminants.
  • Periodic inspections for any signs of wear or damage, especially around the edges and points of installation.
  • Professional assessments or servicing, particularly for structural applications like glass balustrades or facades.

Superb customer service from the Express Toughening team – when I made a mistake on my order online, they dealt with the issue quickly organising partial refund immediately. My order arrived quickly and their courier messaged me before delivery to check I was in. Quality product at the best price I found online.

Andy Beviere

Extremely easy company to deal with, glass ordered weeks ago and asked for a specific delivery date due to glass testing and no one being onsite. Delivered on time and when asked for other types glass stated they couldn’t help but recommended an equally helpful company!!

Wouldn’t hesitate to use again.

I’ve used Express Toughening twice now and have been very impressed with the glass they have supplied and also the helpfulness of the staff. The first job was a couple of years ago when they supplied me with a 6mm satin frosted toughened glass door for our shower room. From my measurements they supplied a fabulous door which had the hinge and lock holes cut out and also took into account the out of square measurement of the door frame. It fitted a treat and is stunning to look at.

More recently (late last year) they supplied me with painted toughened glass splash backs (7 items altogether in 6mm glass with the biggest being 2.1 metres long), all cut to my sizes and with numerous switch and socket cut-outs. My local glass supplier said they could not cut out the close together sockets and switches, but Express did and got it spot on!

As with the glass door, the splash backs were delivered to me by Expresses’ own transport and without any problems and quality issues.

After the scary bit of fitting them all the result is faultless and stunning. Thanks go to Alex who helped me with the ordering process and technical aspects of glass splash backs.

4mm toughened glass for greenhouse. Although slightly dubious about ordering from a company I’ve never heard of and not local (300mile away) I’m so glad I took the plunge. A great customer service from Helen and the team from start to finish, clearly there was nothing for me to worry about.

Their website is easy to use and made ordering online a doddle and for those shapes, they don’t have on their website a quick email and rough diagram sorted any issues there. All glass arrived on time well packed and with no breakages.

It’s a company I wouldn’t hesitate to use again and I’d definitely recommend it to others who need quality glass cut to size.

Fantastic service, fantastic prices and fantastic products – I could not recommend Express Toughening highly enough – I got an immediate response to my request for a quotation, and Helen was so helpful in answering my questions. Order placement was easy and everything arrived exactly on time and as promised. I won’t look anywhere else for my next order – great prices (way cheaper than other quotes) and great service!

Thank you!
