Abstract
An improved means for venting building attics has an opening along the peak of a roof, and cap shingles are spaced from the underlying roof portions by an elongated, relatively thin vent. The vent comprises a matting, or matrix of randomly convoluted polymeric filaments heat bonded to a porous, sheet material layer. The sheet material layer overlies the peak opening and is wrapped around the edges of the filament matrix, to prevent entry of foreign material into the matrix, as well as into the attic, while permitting flow of ventilating air, through the peak opening and outwardly beneath the cap shingles.
Claims16
A vent installation on outer, relatively angled surfaces of a building, characterized in that the vent spaces a cap from said angled surfaces to provide a venting flow path for air to flow outwardly from the building through an elongated slot means formed at the juncture between the angled surfaces,
- said vent comprising
- an elongated openwork member providing multiple flowpaths for the venting flow of air from said elongated slot and beneath the cap, said openwork member comprising a resilient self-supporting matrix strip, and
- a sheet material layer secured to and covering said openwork member and adapted to overly said elongated slot, said sheet material layer being an air-permeable filter material having a multiplicity of closely spaced openings for the free flow of venting air therethrough, said openings being relatively small to provide a barrier to the entry of insects into the interior of the building, through said elongated slot.
A method of installing a vent for the peak of a roof formed by relatively angled roof portions, said roof portions having elongated slot means extending along the length of the peak comprising the steps of
- cutting a vent, from a supply of vent material, to a length at least as great as the length of the slot means,
- said vent comprising an elongated matrix strip,
- said matrix being characterized by having multiple flowpaths there through;
- and
- a layer of sheet material adhered to one side of said matrix strip and overlying said slot means,
- said vent material having a sheet material layer covering one surface of said matrix, said sheet material layer having a multiplicity of closely spaced openings for the flow of venting air there through, said openings being relatively small to provide a barrier to the entry of insects into the attic area of the building, through said slot means,
- positioning said vent longitudinally and approximately centrally of said peak, with the sheet material layer thereof directly overlying said slot means,
- securing cap means which extend marginally of the upper surfaces of the roof portions, in overlying relation to said slot means by fasteners which extend through the cap means the vent and into the underlying roof portions,
- said matrix being further characterized by being self-supporting;
- by having a composite strength in compression sufficient to support an overlying cap;
- and by a resilience sufficient to restore it to substantially its original thickness in the event it is compressed during, or after installation,
- the sheet material layer being wrapped around the side edges of the matrix and releasably bonded to the opposite, marginal portions of the upper surface of the matrix, and
- the further steps of releasing the sheet material layer from the end portions of the vent which has been cut from the supply of vent material,
- severing relatively short segments from each end of matrix, and
- wrapping the sheet material layer around the end edges of the matrix and against the top surface thereof,
- whereby a barrier is provided against entry of insects into the interstices of the matrix.
A vent installation on outer, relatively angled surfaces of a building, characterized in that the vent spaces a cap from said angled surfaces to provide a venting flow path for air to flow outwardly from the building through an elongated slot means formed at the juncture between the angled surfaces,
- said vent comprising
- an elongated openwork member providing multiple flowpaths for the venting flow of air from said elongated slot and beneath the cap,
- a sheet material layer covering said openwork member and adapted to overly said elongated slot, said sheet material layer having a multiplicity of closely spaced openings for the flow of venting air there through, said openings being relatively small to provide a barrier to the entry of insects into the interior of the building, through said elongated slots, and
- said sheet material layer being wrapped around the side edges of said openwork member and secured to the marginal edge portions of the opposite surfaces of said openwork member.
A roof vent system comprising two roof portions, angled to a longitudinal peak,
- slot means extending along the length of said peak for venting air from the attic area beneath the roof portions,
- a cap overlying the upper, marginal edge portions of said roof portions, and
- a vent spacing said cap means above said roof portions said slot,
- said vent comprising an elongated matrix strip,
- said matrix strip being characterized by having multiple flowpaths there through;
- by being self-supporting;
- by having a composite strength in compression sufficient to support an overlying cap;
- and by a resilience sufficient to restore it to substantially its original thickness in the event it is compressed during, or after installation, and
- said layer of sheet material adhered to one side of said matrix strip and overlying said slot means,
- a sheet material layer covering said matrix and adaption to overly said slot when said vent is operatively disposed, said sheet material layer having a multiplicity of closely spaced openings for the flow of vent air there through, said openings being relatively small to provide a barrier to the entry of insects into the attic area of the building, through said slot,
- said sheet material layer being wrapped around the side and end edges of said matrix and overlying the upper, marginal portions of the upper surface of said matrix.
A roof vent system comprising two roof portions, angled to a longitudinal peak,
- slot means extending along the length of said peak for venting air from the attic area beneath the roof portions,
- cap means overlying the upper marginal edge portions of said roof portions, and
- a vent spacing said cap means about said roof portions and said slot means,
- said vent comprising an elongated matrix strip,
- said matrix strip being characterized by having multiple flowpaths there through;
- by being self-supporting;
- by having a composite strength in compression sufficient to support an overlying cap;
- and by a resilience sufficient to restore it to substantially its original thickness in the event it is compressed during, or after installation, and
- a layer of sheet material adhered to one side of said matrix strip and overlying said slot means,
- said sheet material layer covering said matrix and adapted to overly said slot when said vent is operatively disposed, said sheet material layer being a non-wicking hydrophobic filter material having a multiplicity of closely spaced openings for the flow of venting air there through, said openings being relatively small to provide a barrier to the entry of insects into the attic area of the building through said slot means.
