Abstract
A roof ridge vent mat for installation overlying an open roof ridge to provide ventilation to a space beneath a roof is provided. The ridge vent mat is a continuous elongate material of randomly convoluted polymeric filaments having an openwork upper face, an openwork lower face, a plurality of hollow recesses extending into the mat and opening into the lower face, and opposite longitudinally extending openwork side edges. The openwork upper face is formed of randomly convoluted filaments formed to provide a relatively flat surface of sufficient density to catch heads of fasteners. The plurality of hollow recesses is defined by a plurality of upstanding openwork walls of convoluted filaments that extend from the upper face to the lower face of the mat. The upstanding openwork walls are arranged in a latticework structure such that no unobstructed passageway extent through the mat through which wind-blown rain and snow can freely pass into the side edges of the mat and laterally pass through the mat. A ventilated roof ridge assembly including the vent is provided.
