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.

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.
