Short title	Damper stops airflow inside duct while firestop seals the gap between duct and wall.
Image title	Section of a duct passing through a fire-resisting wall. Inside the duct a closed fire damper stops the airflow path. The penetration gap between the outside of the duct and the wall is filled with a firestop seal, which stops heat passing around the duct. The two functions occupy different regions.
