How Fire-Rated Doors Are Made In The UAE

Fire-rated doors are an essential safety feature in any building, whether it is a commercial, residential, or industrial structure. These doors are designed to protect occupants and limit the spread of fire in case of a fire outbreak. They are made using special materials and construction techniques to withstand high temperatures and prevent the flames from spreading from one area to another.

In this blog post, we will take a closer look at fire-rated doors, their construction, and the materials used to make them.

What Are Fire-Rated Doors?

Fire-rated doors are doors that have been tested and rated to resist fire for a certain period. They are typically installed in buildings to compartmentalize spaces and limit the spread of fire. Fire-rated doors are designed to prevent the flames from spreading to other areas of the building, which can help save lives and reduce property damage.

Fire-rated doors are tested and rated according to the time they can resist the flames. The most common fire ratings are 20, 45, 60, 90, and 120 minutes. The rating is based on the length of time the door can withstand exposure to heat and flames before it fails. During a fire, the door must remain closed and latched to provide the necessary protection.

Construction of Fire-Rated Doors

Fire-rated doors are constructed using several layers of materials that are designed to withstand high temperatures and prevent the spread of fire. The construction of a fire-rated door typically includes the following components.

Core

The core is the central part of the door, and it is made of fire-resistant material. The core is usually made of a mineral-based material, such as perlite, vermiculite, or rockwool. These materials are resistant to heat and do not combust.

Frame

The frame is the structure that holds the door in place. It is usually made of steel or another fire-resistant material. The frame is designed to withstand the heat of the fire and prevent the door from warping or buckling.

Face

The face of the door is the visible part of the door that is exposed to the environment. It is usually made of steel, but it can also be made of other fire-resistant materials, such as gypsum board or ceramic fiber. The face of the door must be able to withstand high temperatures and prevent the flames from penetrating through it.

Seals

The seals are located around the perimeter of the door and are designed to prevent smoke and flames from passing through the gaps between the door and the frame. The seals are usually made of an intumescent material, which expands when exposed to heat, forming a barrier against the fire.

Materials Used to Make Fire-Rated Doors

Several materials are used to make fire-rated doors, each with unique properties that contribute to the door's fire resistance. The most common materials used to make fire-rated doors include:

Steel

Steel is a durable and fire-resistant material that is commonly used for the frame and face of fire-rated doors. Steel can withstand high temperatures and prevent the flames from spreading through the door.

Glass

Fire-rated glass is used to create windows in fire-rated doors, allowing occupants to see through the door while still providing fire resistance. Fire-rated glass is made by treating the glass with special coatings and layers that help it resist fire.

Gypsum Board

Gypsum board is a fire-resistant material that is commonly used for the face of fire-rated doors. Gypsum board can withstand high temperatures and prevent the flames from penetrating through the door.

Ceramic Fiber

Ceramic fiber is a lightweight and durable material that is commonly used for the face of fire-rated doors. Ceramic fiber can withstand high temperatures and prevent flames from spreading through the door.

Testing and Certification of Fire-Rated Doors

Fire-rated doors must undergo rigorous testing and certification to ensure that they meet the required standards for fire resistance. The testing and certification process involves subjecting the door to fire and heat for a specific period to determine its fire resistance. The door must meet specific criteria, such as remaining closed and latched, resisting heat and flames, and preventing the spread of fire.

Fire-rated doors in the UAE are tested and certified by independent organizations such as Emirates Authority for Standardization and Metrology (ESMA) and Abu Dhabi Quality and Conformity Council (QCC). The doors are assigned a fire rating based on the length of time they can resist fire, with the most common ratings being 20, 45, 60, 90, and 120 minutes.

In addition to fire resistance, fire-rated doors must also meet other safety standards, such as smoke and draft control, sound transmission, and impact resistance. These additional standards ensure that the door provides optimal protection during a fire emergency.

Installation and Maintenance of Fire-Rated Doors

Proper installation and maintenance of fire-rated doors are crucial to their effectiveness in protecting occupants during a fire emergency. Fire-rated doors must be installed by trained professionals who have experience with fire door installation. Improper installation can compromise the door's fire resistance and render it ineffective in a fire emergency.

Regular maintenance of fire-rated doors is also essential to ensure their effectiveness. The doors must be inspected and tested regularly to ensure that they are in good condition and can withstand a fire emergency. The seals around the perimeter of the door must be checked and replaced if necessary to ensure that they are functioning correctly.

Conclusion

Fire-rated doors are an essential safety feature in any building, providing protection against the spread of fire and helping to save lives and reduce property damage. These doors are constructed using special building materials and construction techniques to withstand high temperatures and prevent the flames from spreading from one area to another. They undergo rigorous testing and certification to ensure that they meet the required standards for fire resistance.

Proper installation and maintenance of fire-rated doors are crucial to their effectiveness in protecting occupants during a fire emergency. Building owners and occupants must ensure that fire-rated doors are installed by trained professionals and maintained regularly to ensure their effectiveness. By understanding how fire-rated doors are made, building owners and occupants can make informed decisions about their fire safety needs and take steps to protect themselves and their property in case of a fire emergency.
