ABSTRACT:
A roof venting system of the ridge vent type, the improvement comprising a unique mat covering the ridge slot. The mat is a unitary sheet construction of randomly aligned synthetic fibers which 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. The unitary mat provides the desirable physical properties such as tensile strength, resilience, ability to be transported in rolls and cut to length, ease of joining strips, long term durability in local ambient conditions, water and insect barrier, and low profile, without requiring sheets of dissimilar materials to be bonded together to provide such properties.
