Fire Rated Downlights

Fire Rated & Recessed Downlights


When faced with the task of choosing recessed downlights for your home or business, one of the first questions you maybe asked is; do you want fire rated on non-fire rated downlights?

When a hole is cut into a ceiling to mount a recessed downlight into, a potential fire hazard is created. Plaster board ceilings (for example) have a natural ability to act as a fire barrier. In any building where people maybe living or inhabiting above, the ceiling below must be fire rated. Fire rated downlights are used to restore the fire integrity of a ceiling.

In the event of a fire, the downlight hole is like a gateway that allows fire to spread through, unchallenged. Once the fire starts to spread through this hole it has direct access to the adjoining structure, usually made from wooden ceiling joists. Fire rated downlights seal off the hole and slow down the spread of fire. Modern fire rated downlights are fitted with an intumescent pad which swells up when it reaches a certain temperature and blocks the spread of fire. The fire then has to find another way around - delaying its progress.

This delay allows occupants to escape the building or ideally allows additional time for the fire to be extinguished. You will notice that some fire rated downlights are rated at 30, 60 or 90 minutes. This rating depends on the structure of the building and more importantly how many floors it has. The top floor of a block of flats for example would require a 90 or possibly 120 minute fire rating, whilst a ceiling in the bottom floor of a house would be 30 or 60 minutes.

If you cut into a ceiling you must restore it to its original condition and not interfere with its natural ability to act as a fire barrier. Surface mounted downlights don't need a fire rating, only recessed downlights have this requirement.

Where Should they be Used?

The Electrical Safety Council (ESC) recommends that fire rated downlights should be used in all ceilings, regardless of which type of building they are being installed in. CLICK HERE for more information

Building Regulations

Legally any work carried out at a commercial or residential property must adhere to the Building Regulations. Fire safety is covered by Part B and is split up into Volume 1 for domestic dwellings and Volume 2 for buildings other than dwellings IE commercial buildings.

Which Downlight?

Most LED downlights such as the Aurora M10 DOB are fire rated as standard; this is becoming increasingly popular with other brands meaning you don't always have the option of using non-fire rated. Look out for this symbol on our website that identifies which downlights are fire rated:
