Abstract
The present invention relates to a laminate, adapted to be used as in a roof ridge vent construction, which comprises (a) a matting layer comprising randomly convoluted polymeric filaments, a portion of the matting layer comprising a plurality of truncated pyramidal cusps, with at least one outwardly extending edge portion of the matting layer which is planar with one surface of the matting layer; and (b) a fabric backing bonded to the matting layer and extending outwardly and being bonded to the outwardly extending, planar edge portion of that matting layer.
Claims19
A laminate which comprises (a) a matting layer of randomly convoluted polymeric filaments, a portion of the matting layer comprising a plurality of truncated pyramidal cusps, with at least one outwardly extending edge portion of the matting layer which is planar with one surface of the matting layer;
- and (b) a fabric backing bonded to the matting layer and extending outwardly and being bonded to the outwardly extending, planar edge portion of that matting layer.
A roof vent for a roof ridge having an elongate slot, comprising:
- a continuous, indeterminate length, roll-form layer of randomly convoluted polymeric filaments;
- said layer having a planar portion and a plurality of lengthwise spaced apart cusps projecting from said planar portion;
- said cusps each having a base portion coplanar with said layer and an apex portion;
- and a fabric backing laminated across the apex portions of said cusps for confronting the slot when said roof vent is installed.
A roof vent for filtering air through an opening communicating between the interior and exterior of a building, said roof vent comprising:
- a layer of randomly convoluted polymeric filaments formed to extend over the opening, said layer having a pair of oppositely extending coplanar edge margin flanges and defining a planar portion and a plurality of spaced apart cusps projecting from said planar portion, each of said cusps having a base portion coplanar with said layer and an apex portion;
- and a fabric backing laminated across paid apex portions and being bonded to said coplanar edge margin flanges for overlying the opening when said roof vent is installed.
A roof vent, comprising:
- a continuous, indeterminate length, roll-form layer of randomly convoluted polymeric filaments;
- said layer having a planar portion, a pair of lengthwise extending coplanar edged margin flanges, and a plurality of lengthwise spaced apart cusps projecting from said planar portion;
- said cusps each having a base portion coplanar with said layer and an apex portion;
- and a fabric backing laminated across the apex portions of said cusps and being bonded to said coplanar edge margin flanges.
A roof vent, comprising:
- a continuous, indeterminate length, roll-form layer of randomly convoluted polymeric filaments;
- said layer having a planar portion and a plurality of lengthwise spaced apart cusps projecting from said planar portion;
- said cusps each having a base portion coplanar with said layer and an apex portion;
- a fabric backing laminated across the apex portions of said cusps;
- and a roof ridge defining an elongate vent slot confronting said fabric backing when said roof vent is installed.
A roof vent for filtering air through an opening communicating between the interior and exterior of a building, said roof vent comprising:
- a continuous, indeterminate length, roll-form layer of randomly convoluted polymeric filaments formed to extend over the opening, said layer defining a planar portion and a plurality of spaced apart cusps projecting from said planar portion, each of said cusps having a base portion coplanar with said layer and an apex portion;
- and a fabric backing laminated across said apex portions for overlying the opening when said roof vent is installed.
