An insulation damming device formed from a moisture-proof and fire-retardant material for preventing the build up of thermal insulation around a recessed lighting fixture, fan or other heat producing device is installed in an attic. The device is formed from a vented cover member, a set of vented side panels and a set of mounting flaps. The vents are disposed at regular intervals along the side panels and cover to allow heat and moisture to escape from the enclosed area. Additionally, the vents can be covered with louvers to insure that no insulation enters the area enclosed by the insulation damming device.
