Fire Doors
FIRE RATED DOORS
A fire-rated door is specially constructed to slow or prevent the spread of fire and smoke in a home or building. Both commercial and residential structures can use fire-rated doors.
How can fire rated doors help during a fire?
In the event of a fire, fire rated doors will resist the penetration of heat and flames to slow the fire for a specified time period. By containing the fire and smoke, they provide time for you to exit the building. Fire rated doors act as a shield, they prevent the fire from spreading and they protect the emergency exits of a building for an extended time.
Fire doors are given a fire-resistance rating, and are usually made of a combination of glass, gypsum, steel, timber and aluminium. They are designed to be kept closed, and any gaps between the wall and the door must be filled with a fire resistant sealant.
Fire Dampers
Fire dampers are crucial passive fire protection products and are used in air conditioning, ventilation and heating systems. In general a fire damper works when heat from a fire causes the normal temperature of a room to rise to approximately 165 degrees Fahrenheit i.e. it is designed to close automatically on the detection of heat. The fusible link which is attached to the damper melts causing the dampers' door to close. More specifically they are located in ductwork at the intersection of fire rated barriers in building zones like partitions at the point of duct penetration in order to retain the fire rating of the wall or floor. The fire damper secures the integrity of the existing barrier thus preventing fire penetration before temperatures reach the fire rating level of the barrier itself. Its primary function is to prevent the passage of fire from one side to the other of a fire-rated separation. The damper is manufactured to a high standard of integrity being designed to resist high temperatures for as long as possible.
Smoke Dampers
Whilst fire dampers function to help stop the passage of fire, smoke dampers work in a similar way to preserve the integrity of physical smoke barriers e.g. floors and walls. They can also be found within air conditioning and ventilation ductwork. They also serve the same purpose as fire dampers to enable building occupants to escape and fire fighters to have easy access. However smoke dampers do not have the same stringent temperature restrictions as fire dampers. They are routinely situated in areas where smoke penetration would present particular challenges.
Smoke dampers have two general functions:
As part of a passive smoke system where they are generally activated by smoke detectors, which would also be situated within the duct. They close upon the detection of smoke and prevent the circulation of smoke and air through the duct or ventilation opening.
As part of an engineered smoke control system. This is designed to control the migration of smoke using walls and floors as a barrier.
Smoke dampers close by either an electronic or pneumatic actuator or a spring actuator. They can be reset manually or forced open on a reset signal to the actuator. Pneumatic actuators need air to function properly whilst electrical actuators need power to function successfully. Smoke dampers do not have to be installed in sleeves - they can be installed directly into the duct. However the joints between the damper frame and the duct must be sealed. This is to prevent any air leakage.
