Fire Hoods are recommended and often required whenever ceiling speakers are installed, but what are they and when do you need one?
A fire hood is an enclosure for a ceiling speaker which goes over the top of the speaker and maintains the integrity of your ceiling. Whilst the speakers do not represent a fire risk in themselves, if you are unlucky enough to have a house fire the speakers will not survive the heat for an hour and so will allow the fire to progress upwards at a faster rate than normal. The hoods give an hour’s fire break, ensuring that your house is as protected against fire break as it was pre-installation.
Fire hoods also have the added bonus of providing a good level of of sound proofing between floors, meaning there is a reduced amount of sound travelling upwards from the speaker. This is a very worthwhile benefit if someone lives or works in the room above where the speakers will be installed.
If you have contractors doing your installation they will be legally required to adhere to fire safety regulations, which means you will need to install fire hoods. Whilst you are not legally required to install fire hoods if doing the installation yourself we recommend them due to the issues you may run into with fire inspectors or insurers if you have not adhered to fire safety regulations. However, if the project is within a single story extension, a bungalow or if there is only loft space above the ceiling speakers you would not need to install fire hoods..
The regulation in question is from the IEE Wiring Regulations Handbook:
Regulation 527-02-01 “Where cables pass through a wall or floor that is a fire barrier, the hole round the cable shall be sealed to the same degree of fire resistance as the wall or floor”
We have a range of fire hoods available suitable for varying sizes of speakers. If you know what speakers you are buying then you should purchase the hoody based on the overall diameter and depth of the speaker. The speakers listed below will also provide an adequate amount of acoustic protection.
Lithe Audio 250 Fire Hood = Suitable for circular speakers with an overall diameter of 200mm-250mm and a depth of up to 250mm. *Note - This hoody will provide only the minimum acoustic protection due to it being quite thin, it does however still adhere to all fire safety regulations.
