Which code describes exterior walls and floors/roof masonry or fire-resistive materials with a two-hour fire resistance rating?

Which code describes exterior walls and floors/roof masonry or fire-resistive materials with a two-hour fire resistance rating?

• A. Code 6
• B. Code 3
• C. Code 1
• D. Code 2

Answer: (A)

Fire-resistance ratings tell us how long a building element can resist fire exposure while maintaining its integrity. Exterior walls and floor/roof assemblies made from masonry or fire-resistive materials are designed to stand up to fire for a two-hour period, providing stronger fire separation. In the coding system used for this material, that specific combination is labeled as Code 6. So, Code 6 is the correct descriptor for exterior walls and floors/roof made of masonry or fire-resistive materials with a two-hour rating. Other codes would refer to different ratings or material types, which don’t match this two-hour, masonry/fire-resistive scenario.
