Fire Rated Glass

As the name implies, it is glass that has proven to offer a certain degree of protection in the face of fire.

In short comparison, Tempered glass can last until about 500°F. In contrast, fire-rated glass can typically survive heat in excess of 1600° F. That’s a marked difference in performance. With structural fires capable of reaching extremely high temperatures very quickly, the need for this specialty glass is easy to recognize.The ratings are time increments, reflecting the duration of testing the product endured. That duration is intended to correspond to the length of time the glass should be expected to perform reliably in a fire. So if a product has a 45 minute rating, theoretically you could count on it containing flames and smoke for the first 45 minutes of a fire.
