Glass fire doors are often used in commercial buildings or areas where maintaining a line of sight is essential.

Glass fire doors: Made from specially designed fire-resistant glass, these doors allow for visibility while still providing fire protection.

Steel fire doors can have fire resistance ratings up to 240 minutes or more and are known for their durability and strength.

Steel fire doors: Constructed from steel, these doors provide high fire resistance and are often used in industrial or commercial settings.

Timber fire doors can have a range of fire resistance ratings, typically between 30 and 120 minutes, depending on the specific construction and materials used.

Timber fire doors: Made from fire-resistant timber, these doors are commonly used in residential and commercial buildings.

The primary function of all fire doors is to resist the spread of fire and smoke within a building. This slows the spread of fire and smoke, allowing occupants more time to safely evacuate and giving firefighters a better chance to control and extinguish the fire.įire doors come in various types, materials, and designs to meet specific requirements, building codes, and architectural preferences. When a fire occurs, fire doors help to classify the building by providing a barrier between different sections. This includes checking the seals, hardware, and self-closing devices for any signs of damage or wear that could compromise their performance.

Regular inspection and maintenance: To ensure fire doors work correctly during a fire, they must be inspected, maintained, and tested periodically.

An open fire door cannot effectively prevent the spread of fire and smoke, so this feature is crucial to the door’s effectiveness. Door closers: Fire doors are equipped with self-closing devices that ensure they remain closed when not in use.These seals expand when exposed to heat, filling the gaps between the door and the frame to prevent the passage of smoke and fire. Intumescent seals: Fire doors are fitted with intumescent seals around the edges of the door and the frame.The rating is determined through rigorous testing, during which the entry is exposed to extreme heat and pressure to simulate real-life fire conditions. The higher the rating, the longer the door can hold back the fire and smoke. Fire resistance rating: The fire-resistance rating indicates how long a fire door can withstand exposure to fire.These materials help to keep the fire and smoke from spreading through the door.

Fire-resistant materials: Fire doors are made from materials that can withstand high temperatures, such as steel, timber, or glass, and are constructed to meet specific fire resistance ratings.

Here’s a general overview of how fire doors work: They are an essential part of a building’s passive fire protection system and help to classify the building, allowing occupants more time to evacuate safely and firefighters more time to respond. Hardware and components: Fire door assemblies include specific hardware, such as hinges, locks, and latches, designed to withstand high temperatures and maintain the door’s integrity during a fire.įire doors must be installed, maintained, and inspected according to local building codes and regulations to ensure proper performance during a fire.įire doors provide a barrier to limit the spread of fire and smoke within a building.This is important because an open fire door is ineffective in containing fire and smoke. Door closers: Fire doors are usually equipped with self-closing devices that ensure the door is permanently closed when not in use.In a fire, the seals expand when exposed to heat, sealing gaps between the door and the frame to prevent the spread of smoke and flames. Intumescent seals are installed around the edges of a fire door.Typical ratings are 30, 60, 90, or 120 minutes, depending on the specific requirements of a building’s fire safety design. Fire resistance rating: Fire doors are rated based on how long they can withstand fire exposure.They can be found in commercial, industrial, and residential settings. These doors are an essential component of a building’s passive fire protection system and can help protect lives and property by providing a barrier between different building sections.įire doors are typically made from fire-resistant materials such as steel, timber, or glass and are constructed to meet specific fire resistance ratings. A fire door is a specially designed door that primarily prevents the spread of fire and smoke within a building.
