Fire resistance rating

Fire resistance rating indicates how long a building component, like a wall or door, can withstand fire and maintain its structural integrity, prevent heat transfer, and contain flames. Measured in hours (e.g., 1-hour, 2-hour), it helps ensure safety by delaying the spread of fire, giving occupants more time to evacuate and firefighters better access. This rating is determined through standardized testing and is essential for designing buildings that meet safety codes and protect occupants.
