Installing ceiling speakers in your audio project? you may need fire hoods

At Smart Home Sounds, we are often asked whether fire hoods are worth the extra spend when installing ceiling speakers. The simple answer to this is that they should be installed unless there is a reason not to do so.

Let's explore fire hoods in more detail.

What are ceiling Speaker fire Hoods?


A speaker hood is a piece of material made from a sound and fire retardant acoustic foam that engulfs the part of the ceiling speaker that is exposed within the ceiling void. The benefits of installing a speaker hood is two-fold:

  1. It prevents the spread of fire in the ceiling void.
  2. It reduces the amount of sound from leaking into the room above, acting as a form of acoustic backbox. 

Speaker hoods are generally very simple to install and most are universal which means they can be used with both 6.5-inch or 8-inch ceiling speakers, with a maximum cut-out diameter of 300mm.

How do I know if I need fire hoods?

Speaker hoods are normally a necessity whether it’s for a residential or office building, new or old. Building safety regulations state that if a hole is cut into the ceiling of your building then you should replace the hole with another material that is at least the same fire and acoustic ratings as what you've removed. This is where fire hoods come in.

In compliance with UK Building Regulations fire hoods are required to reinstate the fire barrier of the original ceiling when ceiling speakers have been installed beneath a habitable living space

So as a general rule, if there is a habitable room above e.g. if you are installing in an apartment, office block or other building that has a habitable room above, speaker hoods are advisable and essential if the floor above is made from chipboard or timber. 

Speaker hoods are also required for ceiling speakers that are installed in a kitchen where the risk of fire is heightened or where there is a bedroom directly above. 

Unfortunately, it is becoming increasingly common for home insurance companies to reject claims for fire damage caused by the building's ceiling integrity being compromised by the installation of ceiling speakers without protective fire hoods.

If you are in the trade, we would definitely recommend insisting your client opts for them, because unfortunately, the installer would be liable in the event of any compromises to the ceiling.
