The Purpose And Importance Of Fire Doors

Fire doors help to decrease the spread of fire and smoke by acting as a barrier. The frame of the door, the door panel itself, and the hardware attached to the door all play a part in presenting an impediment to the advancement of fire.

According to Online Door Store, not all fire doors are made equal, and so each door will have a fire rating depending on how long the door can resist the fire before burning and breaking. For example, a rating of FD30 gives thirty minutes during which persons in the building have time to escape before the door burns through. Certain doors can even have a rating of FD60, giving sixty minutes of time before they breach. The difference in the ratings lies in the integrity of the door and depends on the materials used to construct it. Fire doors are generally made from a combination of materials, and these are what gives the fire door its strength and resistance against burning.

Fire doors are considered to be a passive fire safety system, and they may be used to protect both domestic and commercial buildings. They act by confining the fire to a specific area, and so stop the fire from spreading to the rest of the building. This gives anyone in the building enough time to evacuate before the fire can manage to spread. Time isn’t the only factor, however, since often fire will spread quickly and will block escape routes. The presence of fire doors also decreases the chance of the fire destroying the rest of the building, since it buys time during which the fire has higher chances of being extinguished. 

Certain buildings need to have fire doors by law. This includes apartments and commercial buildings. For fire doors to be useful, they must be kept shut. Your architect may determine that you need a fire door in certain areas that contain a source of the fire. If an accident should happen, this would give your family crucial extra time to get away from danger. 

One of the key components of a fire door is the intumescent strip. This is a seal that runs around the edge where the door meets the frame. Its purpose is to trap smoke and prevent it from entering through the door. It does this by expanding with heat when there is a fire, thus filling the gap around the door and sealing it. It is made with low friction fibres and so helps the door to close effectively and form a seal with the surrounding door frame. 

In a fire, every tiny detail and every split second counts. The efficacy of fire doors depends on their correct installation and maintenance. Each component needs to be fire-rated, and it is crucial that the manufacturers instructions are followed. Fire doors are complex life safety systems, and they require highly compatible components to keep the door securely on the frame as well as to keep smoke and fire out.
