Abstract:
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 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.
