Abstract
Ridge vents and deck covers are disclosed that have a fibrous mesh mat and a moisture barrier. The mesh mat may be contoured to define a variety of structures and may have regions of relatively higher fiber density and regions of relatively lower fiber density. Solar cells may be exposed on the ridge vents to collect solar energy when the vents are exposed to sunlight.
Claims17
A ridge vent comprising:
- an elongated strip of fibrous material comprising randomly aligned fibers joined by binding agents and cured to produce an air-permeable mat having a top side, a bottom side, opposed edge portions, and a central portion between the opposed edge portions;
- the air-permeable mat being sized to be installed along a ridge or hip of a roof covering a ventilation slot formed along the ridge or hip;
- wherein, when the ridge vent is installed along the ridge or the hip of the roof, the bottom side of the air-permeable mat directly contacts the roof;
- the air-permeable mat having a longitudinally extending air gap formed in the fibrous material along the bottom side of the air-permeable mat;
- wherein the air gap separates the opposed side portions and is configured to facilitate bending of the air-permeable mat along the central portion of the air-permeable mat;
- and
- a moisture barrier on the top side of the air-permeable mat and configured to reduce rainwater from penetrating into the air-permeable mat when the ridge vent is installed along the ridge or hip of the roof;
- wherein the moisture barrier is integrated with the air-permeable mat so as to bend therewith and form an outermost exposed surface of the ridge vent when the ridge vent is installed along the ridge or hip of the roof;
- wherein the ridge vent is configured to be installed along the ridge or hip of the roof without a cap shingle installed on top of the moisture barrier.
A roof vent for installation along a ridge or hip of a roof covering a ventilation slot, the roof vent having longitudinally extending opposed edge portions flanking a longitudinally extending central portion and having an upper layer that is substantially impermeable to moisture, and a lower layer beneath the upper layer and integrated with the upper layer, the lower layer comprising an open weave mat that permits a flow of air therethrough from the central portion of the roof vent toward the edge portions of the roof vent, at least one region of the open weave mat having an air gap formed in a bottom surface of the open weave mat and extending longitudinally along the central portion of the roof vent, the air gap configured to facilitate folding of the roof vent over the ridge or hip of the roof;
- and
- wherein, when the roof vent is installed along the ridge or the hip of the roof, the open weave mat directly contacts the roof;
- wherein the upper layer comprises a moisture barrier integrated with the open weave mat so as to be foldable therewith, and is configured to reduce rainwater from penetrating into the open weave mat when the ridge vent is installed along the ridge or hip of a roof;
- wherein the roof vent is configured to be installed along the ridge or hip of the roof without a cap shingle being applied over the moisture barrier of the roof vent, and with the moisture barrier forming an outermost surface of the roof vent.
A roof system, comprising:
- a roof deck;
- a ridge or extending along the roof deck and having a ridge slot extending therealong;
- a plurality of ridge vents positioned along the ridge or hip and configured to cover the ridge slot;
- wherein each of the ridge vents comprises:
- an air-permeable mat having a top side, a bottom side, opposed edge portions, and a central portion between the opposed edge portions;
- wherein the air-permeable mat includes a longitudinally extending air gap formed along the bottom side of the air permeable mat;
- wherein the air gap separates the opposed side portions and is configured to facilitate bending of the air-permeable mat along the central portion of the air-permeable mat;
- wherein, when the ridge vent is installed along the ridge or the hip of the roof, the bottom side of the air-permeable mat directly contacts the roof deck with the air gap overlying the ridge slot;
- and
- a moisture barrier applied along the top side of the air-permeable mat and configured to reduce rainwater from penetrating into the mat when the ridge vent is installed along the ridge or hip of the roof;
- wherein the moisture barrier is integrated with the air-permeable mat so as to bend with the air-permeable mat and forms an outermost exposed surface of the ridge vent when the ridge vent is installed along the ridge or hip of the roof;
- wherein the ridge vent is configured to be installed along the ridge or hip of the roof and secured to the roof deck without a cap shingle installed over the moisture barrier.
