1. A method of forming a fire resistant synthetic fiber and mineral fiber mat comprising:
heating a plastic to a liquid state to create liquid plastic;
extruding said liquid plastic through a first extruder to create a plurality of first continuous synthetic fiber filaments;
drawing said first continuous synthetic fiber filaments through a first vacuum venturi tube;
drawing a plurality of continuous mineral fiber threads through a second vacuum venturi tube;
randomly dispersing said plurality of continuous mineral fiber threads and said continuous synthetic fiber filaments so that said plurality of continuous mineral fiber threads and said continuous synthetic fiber filaments are mixed and dispersed across a web forming belt to thereby create said fire resistant synthetic fiber and mineral fiber mat.
