Fire ratings for glass can range anywhere from 20 minutes to 3 hours. There are two types of glazing options, fire-protective and fire-resistant. It’s important to know the differences between the two in order to choose what’s best for your needs.
Fire-protective glazing helps protect against the spread of flames and smoke for a period of time, but does not block radiant and conductive heat.
Fire-resistant glazing offers the same protection as fire-protective glazing, except it blocks radiant and conductive heat as well.
Some commercial applications for fire-rated glass include storefronts, walls, floors, doors, and openings.
