Intumescent Fire/Acoustic Hood
for In-Wall Speakers up to 350mm x 450mm
With speakers installed in the ceiling, the integrity of a plasterboard or suspended ceiling can be compromised to offer only 4 minutes of fire protection.
Results in simulated fire tests carried out by the British building research team show that from the initial ignition of a fire in a typical lounge, the fire can reach 350°C in just 3 minutes. Within this time the ceiling surface can be alight, with flames penetrating into the light and speaker fittings. A standard in-ceiling speaker of plastic construction lasts for around 40 seconds at these temperatures, giving little or no protection to the ceiling void into which it is installed.
It is a legal requirement for all in-ceiling speakers that are installed below any habitable rooms or means of access or escape. A standard two storey house will require all the ground floor speaker locations to have hoods fitted. If a house has three storeys, you will need hoods on all ground floor speaker and first floor speaker locations to correctly comply with the regulations.
Hoody™ speaker hoods are designed to restore the integrity and fire protection required by British Standards. They reinstate the integrity of the original ceiling as if the ceiling speakers had not been installed. They do this by swelling and increasing in volume when exposed to extremes of heat.
Hoody™ speaker hoods have undergone fire resistance tests employing the general procedures and criteria of BS476 Part 22, 23 and 23 (Clause 5 1987) in various ceiling and floor constructions.
