Fire resistance is the ability of a material or building assembly to withstand fire for a specified time. In HVAC and building design, fire-resistant walls, floors, doors, and duct penetrations slow the spread of fire and smoke, protect structural integrity, and provide safe evacuation time. Ratings are typically measured in hours based on standardized tests.
In a high-rise, fire-rated walls and duct penetrations compartmentalize a fire, slowing spread while HVAC safety features help protect occupants.
