What is a fire door?

Fire doors are specialist doors are purpose-built to withstand fires for as long as possible. They enable buildings to compartmentalise and delay the spread of fire from one area to another and form a crucial part of a passive fire protection strategy.

Certified fire doors will be given a fire-resistance rating, which details the length of time the door set and its materials will be able to with stand smoke and fire depending on the rating.

Why do you need to provide fire doors?

  • They are a legal requirement for flats which open onto communal areas shared with other tenants. This is to make sure crucial escape routes are protected if a fire breaks out.
  • They are designed to automatically close behind you in the event of fire, holding flames back and stopping the spread of the fire and toxic smoke into escape routes, corridors, and other flats in the block.
  • They are specifically designed to withstand fire for up to 30 minutes.
Background
  • 75% of all fire deaths are caused by smoke inhalation
  • Over half of fire-related deaths occurred in rooms where the fire did not originate
  • Smoke can fill a 20 by 20 by 20-foot room through a pencil sized hole in less than 4 minutes.

How long does a fire door protect you for?

There are different grades of fire door, and each one provides a different level of protection. The grades are separated by how long they can withstand fire. The most common types are FD30 (30 minutes), FD60 (60 minutes), FD90 (90 minutes) andFD120 (120 minutes). A fire door can also protect from smoke and will have the prefix FDS if it is also smoke rated.

The main aspect that differentiates the grades is the ‘certified core thickness’ of the doors. This is the core material of the door over which there can often be aesthetic layer of different material.

FD30and FD60 are generally used internally for offices and residential buildings. Any grades over FD60 are more common for the protection of highly valued properties or core infrastructures (for example, archives or server centres).

How do fire doors work?

Fire doors are fitted with intumescent strips in a groove on every edge of the door or fire door frame. When a fire breaks out, the heat causes the intumescent strips to expand to fill the gap between the fire door and the frame. This seals the room and stops the spread of fire for a given time.

Are intumescent strips required on fire doors?

Yes, intumescent fire seals are required on all fire doors. Newer doors and frames have a channel cut into them for rebated seals (if not supplied with seals already in place). For older doors, surface-mounted seals can be used instead.

According to Article 17 of the Regulatory Reform (Fire Safety) Order 2005,it is a legal requirement for businesses to ensure that fire resisting doors and escape doors are correctly installed and adequately maintained at all times.
