“Any combination of fire door, frame, hardware and other accessories that
together provide a specific fire-resistant rating to the opening in terms of its

fire separation walls. Fire door is a component of fire door assembly.”
Fire Stop – For the building to function, utility services are needed
which create penetrations through the compartments. Such utility
penetrations create a breach in the fire barrier and hence are
required to be sealed by fire resistance systems. These systems
are called fire stop systems.
In terms of NBC 2016, Fire doors are defined as follows:
“A fire-resistant material, or construction, having a fire resistance rating of
not less than the fire separating elements, installed in concealed spaces or
between structural elements of a building to prevent the spread/propagation
of fire and smoke through walls, ceilings and the like as per the laid down
criteria.”
