What are the 2 types of fire rated glass?
CLASSIFICATIONS. There are three available classifications for fire-resistant glass: integrity (E), radiation control (EW) and insulation (EI). Fire-rated glazing systems offer passive fire resistance.

So, one good way is to look thoroughly at the edges of the glass. Tempered sheets have smooth and even edges because of the extra processing it goes through. On the other hand, if the glass is not tempered, the edges feel rough to touch.
Is tempered glass heat resistant?
Tempered glass is the less expensive alternative, and is best for lower temperature applications. It can withstand constant temperatures of up to 470 degrees F. Tempered glass is regular glass that has been strengthened through thermal or chemical treatment.
What is added to glass to make it heat-resistant?
Heat-resistant glass is commonly consisting of a soda lime or silica that is a heat-resistant material, with a very low expansion coefficient and a high melting point. Heat resistant glass is a type of glass that is designed to resist thermal shock.
What temperatures can tempered glass withstand?
It also has high thermal strength, when compared to annealed glass, can withstand a temperature differential of 250ºC, and is stable in temperatures ranging from -70ºC to 300ºC. Tempered glass can withstand extremes of heat and cold. At 300 degrees centigrade it can be sprayed with ice-cold water and remain intact.
