ABSTRACT:
An improved roll-form vent for buildings comprises a sequentially thermoformed polymeric vent which provides multiple venting air flow paths between the interior of a building and ambient atmosphere. The vent includes projections extending from a web and a plurality of vent openings that cooperate with screening to bar entry into the building of water, insects and foreign matter. A method of making the vent includes steps of providing a web of material of indeterminate running length, heating the web, sequentially thermoforming the web, cooling the web and rolling the formed vent for storage, shipment and use.
