Ridge vent mat and roof ridge assembly

摘要

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.

主权项

1. A roof ridge vent, consisting of a continuous, elongate mat of randomly convoluted polymeric filaments without any dissimilar materials laminated thereto,
said mat having
an openwork upper face,an openwork opposite lower face,a plurality of hollow recesses extending into the mat and opening only into said lower face and not said upper face, andopposite longitudinally-extending openwork side edges, said plurality of hollow recesses being separated and defined by a plurality of upstanding openwork walls extending from said upper face to said lower face and made of said randomly convoluted polymeric filaments, said plurality of upstanding openwork walls being arranged to provide a latticework structure such that said plurality of recesses is arranged in a grid pattern defined by said latticework structure of said upstanding openwork walls and such that said upstanding openwork walls extend diagonally across said mat relative to said side edges and a longitudinal axis of said mat, the randomly convoluted polymeric filaments forming said openwork upper face of said mat having been subject to a flattening process while the filaments were capable of deformation and before the filaments had hardened so that the filaments extending along said openwork upper face provide a flat surface, extend within a common plane, and said randomly convoluted polymeric filaments being self-bonded and fused together, and the openwork upper face of said mat having a higher density of filaments than a remainder of said mat extending below said openwork upper face.
