Glazing in Fire Rated Doors

- Mar 04, 2019-

Today’s fire rated doors frequently incorporate glazing to enable vision and transparency that maximize natural or shared lighting as well provide additional security to areas that would be otherwise closed-off. Having large vision panels in fire doors provide important safety functions as well. During a fire, first responders are able to see inside the room and visually assess the situation, enabling them to be more effective.

However, the glazing used in fire rated doors typically have additional fire and safety requirements, which can be confusing. Over the years, the International Code Committee (ICC) has endeavored to clear up this confusion by adding specific provisions in the building code.
