Abstract
A mesh ridge vent has an air permeable layer formed of randomly aligned synthetic fibers that are opened and blended, randomly aligned into a web by airflow, joined by phenolic or latex binding agents, and heat cured to produce an air-permeable varying mesh. A moisture barrier may be integrally formed above the air permeable layer and may be defined by a coating or by a layer of fibers that is sufficiently dense to inhibit penetration of water into the web. The mesh ridge vent has edge portions and a central portion and the edge portions may be more dense and thicker while the central portion may be less dense and thinner than the edge portions.
