What are vents that are specifically designed to release heat and smoke called?

The term that specifically refers to vents designed to release heat and smoke is "fire vents." These vents are part of a fire protection system within buildings, designed to allow heat, smoke, and harmful gases to escape during a fire. By facilitating the upward movement of hot gases and smoke, fire vents help protect occupants and assist in controlling the fire itself. This design is crucial for maintaining visibility and reducing heat levels in a burning environment, thus enhancing the safety of individuals and aiding firefighting efforts.

The other terms listed do not accurately describe vents intended for this specific purpose. Heat vents could refer to any vent that allows heat to escape, not specifically in the context of a fire. Exhaust vents are typically used for general ventilation purposes and not specifically for fire scenarios. Airflow vents are more generic, lacking specific reference to fire safety. In this context, "fire vents" is the precise terminology reflecting their purpose in fire safety and building design.
