Fire Door Installation & Maintenance
A fire door is a door that has a fire protection rating. Fire doors are usually installed as part of a passive fire protection system with the aim of preventing the spread of fire and smoke to other compartments of a structure.
In the UK, a fire door is mentioned in Part B of the Building Regulations. These regulations state that fire doors are part of minimum requirements for fire protection that must be in place in all buildings.
Essentiality of Fire Doors
Fire doors are an essential part of a comprehensive passive fire protection system and a building with occupants in the UK must legally have them. Buildings must have maintained fire doors to contain a fire within one compartment and stop the spread of flames, gasses and smoke.
Due to regularity of use, fire doors can soon become ineffective in any building. Therefore, it is essential that routine and regular maintenance takes place to keep fire doors operating effectually.

Fire Door Composition
Fire doors are made up of multiple crucial elements that make them fire-resistant and useful in the case of a fire. Usually, fire doors are made up of a combination of materials such as:
The door frame
The door frame of a fire door will always have fire and smoke seals and door hardware, and fire doors need supporting structure that holds it in place under the strain of heat and hire.
All of the components of a fire door make up an assembly called a doorset. Each doorset has a rating that informs how long a door will be resistant to fire.
Types of Fire Doors
Fire doors are created from a variety of different materials with varying fire ratings and resistance to fire. Here are typical fire door examples:
Steel Fire Doors
Steel fire doors are often used for longer fire resistance periods (120 minutes up to 6 hours), or in areas where higher levels of ware and tear or traffic are expected. All elements of the doorset must be tested or assessed by a third party body to support its performance and installation has to be carried out in accordance with the manufacturer’s instructions.
Glass Fire Doors
Glass can be an effectual material for fire protection due to advanced fire resistance technology. Glass fire doors are made from fire resistant glass that has been created, treated and tested to ensure that it is resistant to fire for long periods of time. Fire resistant glass is often given E classification. Fire resistant glass will remain transparent even when exposed to fire and heat, providing maximum visibility
Timber Fire Doors
Timber fire doors are given an FD rating, telling you how long the door will remain effective under the pressure of heat and flames. All timber fire doors undergo rigorous tests in which the integrity of the door is determined. Tests are conducted on all elements of the doorset, to ensure that all components can retain their integrity when exposed to flames, smoke and heat.
