ABSTRACT:
A dam assembly for preventing the build up of thermal insulation around a recessed lighting fixture in the attic space of a building which includes a plurality of fire-proof, pre-cut panels which may be joined together at the site by clips so as to surround the portion of the fixture extending into the attic space and allow free circulation of air thereabouts so that excessive heat build up is avoided. The dimensions of the pre-cut panels are such that joist spacings of 16 and 24 inch on centers can be accommodated.
