Guard for isolating recessed ceiling lights from combustible insulation

A guard for placement in surrounding relationship to a recessed light fixture in an insulated ceiling comprising a substantially vertical sleeve body formed of thin gauge sheet metal of sufficient height to extend well above the maximum depth of insulation in a ceiling, said sheet metal being coated on at least the outer side of the sleeve body, the sleeve body being open at its top and defining a cooling and ventilating chamber around the recessed light fixture, and an anchoring element on the lower end of the sleeve body projecting approximately perpendicular to the axis of the sleeve body and adapted for stapling to a ceiling structure, said sheet metal being pre-creased transversely at a plurality of equidistantly spaced points for ready formability, said anchoring element comprising a plurality of circumferentially spaced tabs between pre-cut slits in one edge of the metal sheet at each crease, and fasteners securing said sheet into said sleeve body.
