Tempered glass is highly strengthened, made by thermally processing an annealed glass. It is a type of safety glass manufactured with the aid of heat or chemicals used to strengthen the glass. This process is called ‘tempering’. PSG’s Saif Tough, tempered safety glass is 4 to 5 times stronger than the annealed glass of the same size and thickness. But is this glass fire-rated too? Let’s find out!

What is Fire-Rate Glass?

To know if tempered glass is fire-rated glass, you need to understand what it actually is.  Fire-rated glass (also known as fire-resistant glass), on the other hand, can assist prevent flames and smoke from moving from one room to the next. In the case of a fire, all fire-rated glass functions as a barrier to assist restrict the spread of flames and smoke. It’s a special safety glass that has been shown to give long-term fire protection in a Fire Resistance Test.

Is Tempered Glass Fire Resistant?

Tempered glass is heat resistant, however, be aware that it is not fire-resistant unless it is manufactured to be fire-resistant as well. Standard Saif Tough glass products have a fairly high heat rating; these materials generally shatter around 500 °F. But this is not high enough to ensure optimal safety. Fire-rated glass, on the other hand, is specially manufactured to be able to withstand high heat. It can withstand temperatures up to 1500 °F – 1600 °F, making for a highly reliable fire barrier that can prevent the spread of flames, fire, smoke, and extreme radiant and conductive heat. For instance, using fire-rated glass for doors can greatly decrease the chances of injury and death.

At Pakistan Safety Glass, you can acquire a fire-rated tempered glass on order. Our team of expert glass processors takes sheets of this glass and laminates multiple layers into one with a special film to manufacture fire-resistant safety glass.
