The term “fire-rated glass” refers to the complete set of fire-rated glazing products available in the market. Within that wide category, designers can choose from both “fire-protective” and “fire-resistive” glazing products, depending on their project’s requirements. Fire ratings for glass, which are noted on a product’s label, range from 20 minutes to 3 hours, with the specified number corresponding to testing by independent laboratories (in accordance with fire test standards). The rating reflects the amount of time the material is anticipated to remain in place to help stop the spread of fire and smoke.
