ABSTRACT:
An insulating fiber mat is comprised of a plurality of fibers bound together by a binder means and distributed throughout the mat. At least some of the fibers throughout the mat are inclined. The inclined fibers on opposed sides of a central horizontal plane of the mat have opposed angles of inclination. This permits the fiber mat to be easily separated substantially along the central horizontal plane by applying a pulling force on one side of the mat in the direction of the inclined fibers.
