Toughened Vs. Laminated Glass

Toughened glass is an essential material in modern architecture since it adds resilience to your building while also adding aesthetic value to your décor. Safety glass comes in two different kinds: toughened glass and toughened laminated glass. Although both Toughened glass and Toughened Laminated Glass prevent injuries and accidents, they have unique properties that set them apart. With the new trend of environmental protection and energy conservation, many people in Nepal choose toughened glass for added security because it takes much more effort to break than laminated glass, while some also opt for toughened laminated glass because it offers more protection than toughened glass in terms of sound reduction and UV resistance. However, there is no clear-cut answer to the question of whether to use toughened glass or toughened laminated glass for a certain application, except for the circumstances when it is blatantly obvious, such as on a car windscreen.

Bimba aims to educate you about the essential differences, advantages, and uses of both Toughened Glass and Toughened Laminated Glass, so you may choose the one that best suits your needs and help you answer all your questions to decide all you need. Read on.

What is Toughened Glass?

Toughened glass, also known as tuffen glass or tempered glass, is a high-strength safety glass that is up to five times stronger than regular glass and breaks in a safer manner. It is also four to five times more heat resistant than regular glass and can endure temperature swings of up to 250°C. 

Many people do, however, wonder how toughened glass is so strong than regular glass? It is made from annealed glass that has been rapidly compressed after being heated to around 650° C and subjected to controlled heat or chemical processing. By doing so, the glass pane heats beyond its transmission temperature, softens, and experiences large compressive and tensile strains. This makes the glass much stronger compared to regular glass and breaks with considerably less force.

Is Toughened glass unbreakable?

As we mentioned earlier, toughened glass is five times stronger than regular glass, and thus can withstand loads without breakage. But, is it glass unbreakable?. The straight answer is “NO”. Toughened glass is susceptible to breaking under certain instances. Fitting the panels too tightly, knocking or putting excessive strain on the corners can cause toughened glass to explode. However, when broken, it shatters into tiny granular fragments as opposed to sharp shards like regular glass does. These little bits are less likely to hurt someone. Toughened glass is, therefore, utilized in a range of demanding applications due to its safety and strength.

Toughened glass also has a surface compression resistance of at least 10,000 lbs. It provides your property with an additional degree of security and is extremely strong and durable. Additionally, toughened glass can resist temperature swings that are as high as 250°C. Likewise, it has a high level of resistance to electric shocks.

Uses of Toughened Glass

Because of its structural strength, toughened glass is preferable in glass desks, doors, and walls in offices to improve the system’s overall appearance and in architectural applications including glass doors, partition walls, and side windows. Now, let’s dig in deeper.

Toughened glass is the material most often used in shower cabinets. Your shower cabinets will continue to look brand-new for many years, thanks to toughened glass. It is resilient, long-lasting, adaptable, and easy to clean. In the event that tempered glass breaks, it scatters into harmless tiny fragments that are comparatively safe to handle.

Because it fractures into blunt pebble-like bits and won’t seriously hurt employees, toughened glass is excellent for workplace cabins and partitions. Additionally, toughened glass is a fantastic option for the outside of office façades.

What are the benefits of using Toughened Glass ?

As mentioned earlier, toughened glass has its own unique benefits and now that we are aware of what toughened glass is, let’s review its noteworthy benefits;

  • Instead of splintering into sharp chunks, toughened glass breaks into tiny, granular bits that are less likely to injure someone.
  • It is resistant to heavy downpours and hailstorms and can withstand mild wear, scratches, and high winds. You feel more secure thanks to its high level of durability, which makes it hard to break.
  • It can withstand extremely high temperatures and has exceptional thermal resistance. Toughened glass has an SPF of around 16, since it absorbs 65% of UV radiation.

What is Toughened Laminated Glass?

Toughened laminated glass is one of several various varieties of toughened glass and as the name suggests, toughened laminated glass is basically a blend of laminated and toughened glass. An extremely tough and durable EVA (ethylene-vinyl acetate) or PVB (polyvinyl butyral) plastic interlayer holds two pieces of glass together to form toughened laminated glass. To help you understand this better, let’s have a look at this picture.

The special feature of laminated glass is that even if it breaks, toughened laminated glass will stay in place since it is glued to the PVB layer. It is used in skylights and glass ceilings for this purpose to prevent glass from breaking and falling from above.

Uses of Toughened Laminated Glass

Toughened Laminated Glasses are ideal for locations where strengthening security is of the utmost importance, such as;

Laminated glass is widely used for storefronts because, in the event that it breaks, the interlayer secures the entire piece, leaving no opening for an attacker to use it to enter the building. Additionally, it offers a layer that is both sturdy and translucent, giving it a very sleek and simple appearance.

What are the benefits of using Toughened Laminated Glass?

Toughened laminated glass offers advantages of its own in contrast to toughened glass. Let’s find out;

  • The plastic interlayer holds it together, making it impact-resistant when the structure is scatters.
  • When toughened laminated glass breaks, the interlayer will typically contain the bulk of the fragments, reducing the impact of the breaking
  • Due to its density, toughened laminated glass dampens the amount of noise let through.
  • It has a unique coating inside that prevents the majority of UV radiation from entering, reducing your air conditioning costs.

What is the difference between Toughened Glass and Toughened Laminated Glass?

While laminated and toughened glass both provide greater breakage protection than ordinary glass, they actually differ quite a lot, particularly in the manner of manufacturing process and the way it shatters. Let’s take a closer look at some of the major differences.
