If you make an opening in the ceiling of a fire separating element in order to install a recessed light fitting you must restore the ceiling's fire-stopping integrity. This is a requirement of both the Building Regulations and the IEE Wiring Regulations 17th Edition. Fitting a recessed downlight can also compromise a ceiling's acoustic properties, enabling sound to readily transmit through the floor above. Building Regulations now require you to maintain the ability of an internal floor to provide reasonable resistance to sound once downlights are fitted in the ceiling. This is where the Aico AFF10915 Fire Hood / Fire Cone / Fire Sock comes in to help!
This firehood from Aico - the AFF10915 Fire Cone / Fire Sock - installs in Seconds but Protects for Life! Ideal for being installed over the downlight - the Aico AFF109/150 Fire Sock / Fire Cone is a great fire protection downlight cover.
