A fire door is a door with a fire resistance rating sometimes referred to as a fire protection rating for closures used as part of a passive fire protection system to reduce the spread of fire and smoke between separate compartments of a structure and to enable safe egress from a building or structure or ship.
What does a fire rated door mean.
It is a fireproof partition with certain fire resistance such as in fire compartments evacuation stairwells and vertical shafts.
When access doors are closed they should block gas smoke and extreme heat from flowing through.
Its main purpose is to hold back smoke and to contain fire.
Fire rated doors can meet fire resistance stability integrity and insulation for a certain period of time.
A fire rated door is a very heavy door made of materials like metal or gypsum.
This is because the door must provide sufficient fire and smoke resistance to provide protection for people using the corridor for example to safely escape or seek refuge in a fire situation.
If a fire breaks out in your kitchen with fire rated doors in place and with all doors closed the fire will take longer to spread to the dining room and break room.
The term fire rated means that the door when installed properly is not supposed to combust during a certain time period in the average fire.
These include exit doors corridor doors and any other protected openings within your building like access doors roof hatches or floor hatches.
Fire rated doors are an important part of a building s fire control system.
Where access to a fire compartment is necessary then the door providing access must be a fire door.
The door itself is usually made from a solid timber frame but they can sometimes be covered again in fire resistant glass.
This glass should be able to withstand exposure to the heat condition in a fire test for at least 60 minutes before it reaches a temperature high enough to soften it.
Fire doors are made up of various components.
Fire rated doors are used in buildings to prevent the passage of fire and smoke between two compartments or areas.
