Abstract
A roof ridge venting system using a mat constructed of randomly-aligned synthetic fibers which are joined by phenolic or latex binding agents and heat cured to provide an air-permiable mat with a varying mesh. The mat is a unitary sheet construction having no dissimilar sheets laminated or otherwise bonded together. In an alternative embodiment for use with heavier slate or terra cota tiles, the mat includes a grid pattern of small solid cores extending through the thickness of the mat.
Claims21
A roof venting system comprising:
- an open slot along substantially the length of a roof ridge permitting air ventilation from the interior space to the exterior;
- an air-permeable mat covering the slot over the length of the slot and overlapping the slot on each side, the mat being constructed of randomly aligned synthetic fibers which are opened and blended, randomly aligned into a web, joined by phenolic or latex binding agents and heat cured to produce an air permeable varying mesh, said mat being of unitary sheet construction and including a grid of solid cores extending through the thickness of the mat for supporting a capping structure thereon;
- a capping structure overlying the mat and spaced away from the roof by the thickness of the mat to provide ventilation through the mat in the space between the capping structure and the roof.
In a roof venting system of the type comprising an open slot along a roof ridge to permit ventilation from the interior space under the roof to the exterior, an air permeable material overlying the slot to permit ventilation while excluding water and insects from entering through the slot, and capping materials covering said air permeable material, the improvement comprising:
- said air permeable material comprising a flexible and resilient mat constructed of a unitary sheet of randomly aligned synthetic fibers joined by phenolic or latex binding agents and heat cured, and including a grid of solid cores extending through the thickness of the mat for supporting said capping materials thereon.
For use in a roof venting system of the type comprising an open slot along a roof ridge to permit ventilation from the interior space under the roof to the exterior, an air permeable material overlying the slot to permit ventilation while excluding water and insects from entering through the slot, and capping materials covering said air permeable and resilient materials, an improved air permeable material comprising:
- a flexible and resilient mat constructed of a unitary sheet of randomly aligned synthetic fibers joined by phenolic or latex binding agents and heat cured, said mat including a grid of solid cores extending through the thickness of the mat for supporting said capping materials thereon.
