What is Tempered Glass?

Tempered glass is a specialist panel that’s designed with enhanced safety in mind; as a result, these panels are often much more stable and less prone to shattering than regular glass sheets.

One of the core goals behind tempered glass is to reduce the danger posed by glass when it shatters. Indeed, this particular material is often substantially more resistant to shattering than untampered options, which helps protect residents and property. Moreover, it is also worth considering that, when it does shatter, the tempered glass breaks into smaller, rounded pieces compared to the often sharp shards produced when untampered glass fractures.

Thanks to this unique nature, tempered glass has a broad range of applications, making it exceptionally useful for building, construction, and even vehicles.

How is Tempered Glass Made?

There are several different processes that manufacturers may use. Still, the general method is to heat the glass quickly to a very high temperature before rapidly cooling it with cool air. This particular process helps strengthen the glass significantly, giving it many excellent properties. The cooling process may only last a matter of seconds, providing an exceptionally rapid re-solidifying process.

Due to this approach, the exterior surface of the tempered glass panel undergoes a state of compression, making it much harder to shatter, break, or smash. Moreover, the tensioned inner surface of the panel experiences much greater tension than normal, further helping to prevent cracks and chips.

Another method used to create tempered glass is chemical tempering. During this process, the glass is submerged in a molten salt bath, which causes ions to be exchanged between the surface of the glass and the liquid. This process creates compressive stress on the surface of the glass, similar to the thermal tempering process – however, the process is much less commonly used overall.

How Do Tempered and Untempered Glass Differ?

Tempered and untampered glass are substantially different from one another, and keeping this in mind is hugely important if you have been looking for a quality solution overall. Indeed, in many cases, it’s easy to assume that tempered glass isn’t that different from regular panes – but in reality, there can actually be a huge amount of change between the two.

Generally speaking, untempered glass is perhaps the most common type of glass used in many projects and designs. One of the great features of untampered glass is that it usually doesn’t have internal stresses; this makes it much easier to cut and shape. However, it’s not as strong as tempered glass, which is worth considering from a safety and practicality perspective. When damaged, untampered glass is hence prone to breaking into sharp and dangerous shards.

In contrast, tempered glass is produced with a focus on strength and safety. The sheet is heated to a very high temperature; then, a rapid cooling process re-solidifies the glass quickly, preventing further damage from occurring. This creates great surface compression on the glass, giving it far greater strength than regular, untempered glass. In turn, it’s generally more resistant to damage; when a large force does cause it to break, it shatters into much smaller, less sharp pieces that are less likely to cause injury.

Further Differences

It’s not just the strength and safety features that differ between tempered and untampered glass. Indeed, the former tends to be more resistant to thermal stress, capable of coping with a greater extreme temperature without breaking. As a result, it’s often ideal for use in high-temperature applications (for example, for oven or fireplace doors).

In addition to this, when building a new property, it’s well worth considering the building codes for your particular location and project. Indeed, in many cases – for example, for use in high-rise buildings – it’s not uncommon for safety legislation to demand tempered glass be used.
