Laminated Glass vs. Toughened Glass – Key Differences Explained

Laminated glass and toughened glass are frequently confused in the world of architecture as one of the same. While both are types of security glass, there are actually some key differences between the two and particularly in the reasons why you would install them.

We’ve broken down the key reasons why and when you should choose laminated glass and toughened glass to help you understand the core differences between these two security glass options.

toughened Glass

Laminated Glass

What is Laminated Glass?

Laminated glass offers the same strength as ordinary flat glass but consists of two pieces of glass which sandwich a middle interlayer, which is typically made from polyvinyl butyral (PVB) or ethylene – vinyl acetate (EVA). If the glass is broken, the middle inter-layer holds the whole pieces of glass either side in place.

Why and when should you use Laminated Glass?

In the event of breakage, laminated glass does not leave a gaping hole for an intruder to use to easily access a premises and there are no large free shards of glass which threaten to injure passers-by. Laminated glass is therefore frequently used in shop windows and shopping centres as well as in the skylights, ground floor doors and windows of residential and commercial buildings.

Toughened Glass

What is Toughened Glass?

Toughened glass is a type of safety glass that has been processed with controlled thermal or chemical treatments through intense heating and rapid cooling. This tempering process used by toughened glass manufacturers puts the outer surface of the glass into compression and the inner surface into tension. This, in turn, forms a rigid outer layer which makes the glass incredibly strong and durable and does not alter the stiffness of the glass.

When broken, toughened glass breaks down into small granular pieces rather than large sharp shards of glass. The greater the surface stress, the smaller the glass particles will be when broken.

Why and when should you use Toughened Glass?

Toughened glass is most frequently used where heat resistance and intensive durability are of utmost importance. It is used in a variety of demanding applications, including vehicle windows, shower doors, architectural glass doors and tables, refrigerator trays, mobile screen protectors, as a component of ballistic glass, in diving masks and various types of plates and cookware.
