How do fire doors work?

Fire doors are designed to prevent the spread of fire and smoke within a building, allowing people to evacuate safely and minimizing damage to property. They work by creating a barrier that blocks the passage of heat and flames from one area to another.

Fire doors are typically made of fire-resistant materials, such as steel or composite materials, minernal fibre wool and calcium silicate board and they are equipped with fire-rated hardware, such as hinges, locks, and latches. When a fire breaks out, the heat from the flames activates an intumescent seal around the door, causing it to expand and seal the gap between the door and the frame. This helps to prevent the passage of flames and smoke through the door, buying time for people to evacuate and for firefighters to arrive and contain the fire.

In addition to their fire-resistant materials and hardware, fire doors are also designed to be self-closing, ensuring that they will automatically close and latch in the event of a fire. This helps to further contain the fire and prevent the spread of smoke and flames.

It's important to note that fire doors are only effective if they are installed correctly, labeled clearly, and maintained properly. If you have specific questions or concerns about fire doors in your building, it's always best to consult with a professional who can provide expert advice and guidance.For more blogs click on
