ABSTRACT:
A device for damming insulation around and away from a heat producing object such as a recessed light fixture is disclosed in its preferred form according to the teachings of the present invention. Specifically, the insulation damming device is formed by the interconnection of one or more insulation damming members to form an enclosure of a size and shape arranged to fit around the heat producing object. The damming members are generally planar and are formed in the preferred embodiment of sheet metal. Top, middle, and bottom extension members extend from the first end edge of the damming member and positively interconnect with top, middle, and bottom series of slots extending along the length of the damming member from the second end edge of the damming member. To increase stability and position retention, apertures are formed in the damming member adjacent the bottom edge for receiving a wire for attachment to a support member. Thus, the damming member can be easily and quickly formed into an enclosure having a perimeter less than, substantially equal to, or greater than the standard sold length of the damming member allowing the fast, versatile, and easy installation of the insulation damming device without the necessary of tools or without cutting the damming member.
