ABSTRACT:
A fire barrier partition having a body with a cavity for receiving and containing molten insulation is disclosed for use in building constructions. The partition is supported between building members in positively wedged engagement. The partition may support a cover which restricts the flow of oxygen into the cavity while allowing molten insulation to flow freely into the partition cavity.
