What is Laminated Glass?

Laminated security glass

What is laminated glass? A lot of people think they know what laminated glass is, but in reality, they only know the gist of it. In this article, we will sweep all of that through and give you everything you need to know about laminated glass.

From understanding what it is, knowing what it’s made of, getting the idea of where they’re used, to what the advantages and disadvantages are, we’ll give it all to you!

What is Laminated Glass?

Custom laminated glass

So, what is the meaning of laminated glass? By definition, it is a glass structure that’s made up of two or more glass sheets bonded by plastic to successfully resist shattering. They’re also called and labeled safety or shatterproof glass.

But what is it actually made of? What comprises laminated glass? That’s what we’ll answer in the next question, which is…

What is Laminated Glass Made Of?

Laminated glass is made up of multiple glass layers stacked alongside each other bonded by polyvinyl butyral or PVB resin glue. Then, this plastic material will be heated, pressed, and bonded together, creating the glass product known as laminated glass.

The glass unit or material can be anything from regular tempered glass or annealed glass. Some manufacturers sometimes often use other glass types in order to accommodate the need or requirement of the client.

Nevertheless, the general structure of laminated glass would usually be standard float glass or tempered glass.

Laminated Glass vs. Tempered Glass

A lot of people have the misconception that tempered glass and laminated glass are the same, but they’re not. They actually have differences that are notable and are exclusive to one another. For you to visualize how they’re similar and different, here’s a table that outlines them both:


Laminated Glass

Tempered Glass


This is the glass type that’s made up of multiple glass layers and interlayers.

The glass type that’s made from highly-fluctuating temperatures.


Windows, glass stairs, glass doors, car windshields, etc.

Shower doors, device screens, kiosks, etc.

Manufacturing Process

The strength and resilience come from the multilayered glass.

The strength comes from the constant heating and cooling.


Laminated glass is cheaper and more affordable.

Costlier and more expensive because of the specialization of the glass.


Laminated glass is comprised of multiple glass layers stacked on top of each other, bound by plastic.

Made from glass products that have been subjected to high heat and cooled down.


It is strong because it can resist force from rocks or bullets without shattering and without being dismantled.

It is strong because it underwent fluctuating temperatures.

These are the differences and main distinctions between laminated glass and tempered glass. So, to sum it all up, they are not the same. Tempered glass cam be modified and developed to become laminated glass by mixing and fusing them all up, but laminated glass couldn’t be made into tempered glass – unless you strip off the glass units.

Laminated Glass Price: Is Laminated Glass Expensive?

Laminated safety glass

Determining and coming up with the exact price of laminated glass can be a bit like chasing a moving target – it’s almost impossible to be singled out. There are several factors that drive the cost, like dimensions, thickness, and any additional features like soundproofing and ultraviolet (UV) resistance.

In the general sense, you’re looking at a range from $10 to $20 per square foot, with customizations nudging the upper limit. That’s the general rate for it, though.

If we look at the standard Chinese market for laminated glass, you’ll notice that it costs anywhere between $0.90 and $90 per unit. On average, they’ll be anywhere around $10 and $25, $25 being excellent quality.

Is Laminated Glass Breakable?

Just because it has high strength properties, doesn’t mean that it’s already indestructible. To answer the question, though, yes and no – let us explain why.

Yes, because laminated glass is typically known to be an unbreakable piece of glass. The term unbreakable refers to glass units that do not scatter or shatter into smaller pieces when they’re broken. So, yes, it is unbreakable. But no, it is not indestructible because it can still break.

This is mainly one of the major reasons why laminated glass is the selected glass type for many applications that require it, such as curtain walls, facades, skylights, railings, automotive windshields, and other things of the like.

Laminated Glass Properties and Specifications

Unlike specific glass types, the specifications available for laminated glass only refers to its overall ability. Because there can be custom laminated glass, the properties and specifications vary, allowing researchers and experts to only classify them generally.

For you to be able to gain a better understanding of what we mean by it, here’s a table that discusses just that.


Laminated Glass

Heat Insulation

Yes and very much effective, especially with the right reflective coating.

Impact Resistance

Low levels of impact resistance

Environment Control and Resistance

High levels of environment resistance and control, protection from UV rays.

Risk of Injury

Low risk of injury because it is safe and secure.

Acoustic Insulation and Soundproofing

Yes, and very much effective.

Optical Distortion

Low optical distortion, clear and visible.

NOTE: The properties of laminated glass depends on its structure and overall composition. The one we showcased in the table is made from standard float glass or soda-lime glass.

Is Laminated Glass Waterproof?

Many like to think that laminated glass is waterproof because of its composition and structure. When, in reality, it’s not. As a matter of fact, some experts point out that laminated glass is actually receptive to moisture, and, therefore, delaminates over time.

Don’t confuse it with specialized glass types, though, like the waterproof laminated glass. These are special requests from companies and businesses that need to further enhance the waterproofness of their glass units.

Why Should You Use Laminated Glass?

As we keep on pinning above, laminated glass is a specialized glass type that’s used in a lot of technologies and usage applications today. Its double walls make it a perfect candidate for strength, resilience, and overall integrity.

The best application you can use laminated glass for is in your home. Since it has UV resistance and is known to block almost 99% of UV light transmission, you can be sure that your home won’t be damned by ultraviolet rays!

Adding to the fact that laminated glass is strong and extremely useful, you really wouldn’t worry about shattering and about the risks involved in them!

How is Laminated Glass Prepared?

The process of preparing of creating laminated glass is actually just a 5-step process. As we always mention, many manufacturers and suppliers have limited ability and skill to convert your standard float glass into laminated glass.

Here’s the general preparation process of how they’re readied up:

  1. The glass units are cut and grinded according to the required shape and size of the laminated glass.
  2. They’re then washed, dried up, and loaded to the laminating equipment.
  3. After that, the surface of the glass is prepared for the process.
  4. It will then undergo the Glass-PVB-Glass integration.
  5. Then, when the structure is prepared and laid out, it then undergoes autoclaving or the heating of the PVB, making the two glass units stick and glued together.
  6. It’ll then be dried up and sealed on its edges for further guarantee that it wouldn’t be harmed.

Advantages of Using Laminated Glass

There are benefits and advantages to using laminated glass, these are:

Enhanced Safety and Security

Laminated glass stands as the thick line between shattered glass risks and dangerous. Thanks to the multi and interlayer structure, the overall glass is kept intact, significantly reducing the risk of injuries and hazardous occurrences.

UV Protection

It’s also an effective tool that can keep ultraviolet light and rays out. This is part of the many reasons why laminated glass is used in residential and commercial applications for windows, car windshields, doors, etc. Think of it as sunscreen for your workspace!

Sound Insulation

The multi and interlayer weakens and eases vibrations, disallowing sound to puncture through one side. It is, therefore, an ideal choice for applications where insulation is needed.

Durability and Longevity

Compared to float glass and standard soda-lime glass, laminated glass is also known to last longer and become more durable. It’s known to have brute strength and resilience against typical breakage and damages.


In case you’re wondering, laminated glass is less costly and more inexpensive than other types of specialized glass like Gorilla Glass, chemically-toughened and strengthened glass, etc.

Disadvantages of Using Laminated Glass

There are also disadvantages of using laminated safety glass (LSG). Here’s a list of the few cons and drawbacks of laminated glass units:

Delamination Capabilities

Laminated glass, even if it’s robust, can also have a hard time with delamination. This can occur when the layers of glass start to separate naturally, potentially compromising its overall integrity. This paints the picture why typical inspections and quality assurance checks are crucial to address early signs of delamination and to catch up and resolve it.


Because of the fact that laminated glass is made up of multiple layers of glass, it is typically heavier than your standard soda-lime or float glass. This can pose problems in transportation and movement, especially if it’s going to be lifted to hundreds of feet above the ground.


Last is its complexity. Laminated glass is not as simple and easy as regular float and soda-lime glass. It has a complex web of structural integrity that’s demands skill. This intricacy is what makes it an excellent choice for certain applications and functionalities.

Those are the listed pros and cons of using laminated glass, and although the drawbacks seem powering, the cons go over them quite tremendously. The number of benefits they have will take over its cons.
