Abstract
The application discloses a fire protection cover for an electrical device recessed into a wall or ceiling, said, comprising one or more support layers coated with one or more layers of intumescent material. The device is especially useful for suspended ceilings or partition walls for preventing the passage of fire into or out of the ceiling or wall cavity. The cover may comprise one or more apertures to enable the cover to be ventilated and/or for access to cabling. In particular, the cover may be made of a mesh or perforated sheet.
In the event of a fire, the intumescent material tumesces to block any holes within the cover or holes between the cover and wall or ceiling.
