Tempered Glass vs. Heat Strengthened Glass: How to Make a Choice?

Tempered glass and heat strengthened glass have different properties, which result in their uses in different scenarios for different purposes. When deciding on which one of them will be selected for your project, you might as well weigh their pros and cons.

Tempered Glass

Advantages:

High mechanical strength: Tempered glass has excellent performance in impact resistance & bending resistance. Compared to the ordinary glass of the same thickness, tempered glass is 5–8 times higher in impact strength and 3–5 times higher in bending strength.

Good thermal stability: Tempered glass has good thermal stability and can withstand temperature change of up to 300℃, which is 3 times stronger than common glass.

Good safety performance: Unlike regular glass, which shatters into sharp shards that can potentially cause injuries, tempered glass breaks into smaller pieces that interlock with neighboring pieces.

Disadvantages:

Distorted surface

There might be spontaneous breakage happening after it is installed.

Heat Strengthened Glass

Advantages:

Not spontaneous breakage.

Heat strengthened glass comes with good flatness and less optical distortion. As a result, it is often used in glass curtain walls and is very suitable for use when transparency is required.

Disadvantages:

There will be large pieces of glass and sharp cracking edges when it breaks that could get people hurt.
