The vents are nominally 8 inches, 10 inches, and 12 inches wide [actual widths are a minimum of 11.25 inches (286 mm), 13.25 inches (337 mm), and 14.75 inches (375 mm), respectively] by 4 feet (1220 mm) long, and bend to contour-fit over ridges of roofs. The vents are available with an optional Weather PROtector filter bonded to the vanes on the underside of the vent to help protect the ridge opening from the entry of weather and debris. The panels interlock to form continuous vents along ridges. The net-free ventilation area (NFVA) is 18 square inches per foot of vent length (3540 mm 2 /m) for the 8-inch- and 10-inch-wide models, and 20 square inches per foot of vent length (3934 mm 2 /m) for the 12-inch-wide model. 3.2 Material: The vents are made of injection-molded polypropylene classified as CC1 plastic under IBC Section 2606.4. The Weather PROtector filter is a nominally 5-mil-thick (0.127 mm), spun-bound, polyester fabric. 4.0 DESIGN AND INSTALLATION 4.1 Design: The required ventilation area must be determined, and sufficient ventilating panels must be installed to provide ventilation in accordance with IBC Section 1203.2 and IRC Section R806. Each panel is marked with the venting area it provides when installed in accordance with this report. 4.2 Wind Resistance: VentSure ridge vents are permitted to be installed on buildings in areas having a maximum basic wind speed (3-second-gust) of 100 miles per hour (160 km/h), on structures having a maximum mean roof height of 40 feet (12.2 m) in Exposure B, C, and D areas. 4.3 Installation: The roof slope must be between 3:12 (25 percent slope) and 16:12 (133 percent slope). A 2-inch-wide or 2 1 /2-inch- wide (57 mm or 64 mm) slot must be cut in the roof sheathing along the ridge, starting a minimum of 6 inches (152 mm) from the rake edge, in accordance with the report holder's published installation instructions. The slot must be cleared of all debris, which would inhibit airflow. The ridge vents must be centered over the ridge and attached to the roof sheathing using the 2 1 /2-inch-long (57 mm), corrosion-resistant, ring shank nails supplied with the vent, with one nail in each nail hole molded into the vents along each edge. The nails must penetrate the sheathing a minimum of 3 /4 inch (19.1 mm), or through the thickness of the sheathing, whichever is less. Successive ventilating panels must be snapped together to form a continuous vent strip. Asphalt ridge shingles must be installed over the ridge vents and fastened through the
