Which of the following is true about the fire-rated construction requirements for garage doors?

• A. Must be hollow core
• B. Must be a solid door at least 1 3/8 inch thick
• C. Can be a standard interior door
• D. Must be 1 1/2 inch thick only

Answer: (B)

The fire-rated construction requirements for garage doors are indeed that they must be a solid door with a thickness of at least 1 3/8 inches. This requirement is established to ensure adequate fire resistance between the garage and the living spaces of a home, as garages often contain various combustible materials and vehicles. A solid core door of this thickness helps to slow the spread of fire and smoke, providing critical time for occupants to evacuate and for emergency services to respond. Fire-rated doors are constructed to meet specific standards, and a solid door meets those necessary fire-resistive properties. While hollow core doors, standard interior doors, or doors that do not meet the thickness requirement may appear functional, they do not provide the required fire resistance and could fail to protect the living areas from fire hazards originating in the garage. Thus, having a solid door that meets the specified thickness is crucial for safety and adherence to building codes.
