18 inch Intake Roof Vent | Pop Vent Model PV-18-C4<\/h3>\n

The 18 inch Pop Vent Air Intake Vent is ideal for maintaining proper attic ventilation. The PV-18-C4 is 18 inches in diameter with a 4 inch tall collar. In other words, this vent has 4 inches of clearance between the base and the inner louvers. In addition, the 18 inch intake roof vent has 254 inches of Net Free Area (NFA) and a standard 28\u201d x 28\u201d square flange.<\/p>\n

Air intake vents allow outside air to enter into attics and ventilation spaces.<\/p>\n

Installation: <\/strong>Ideal for low slope or flat roofs<\/strong><\/h4>\n

18 inch diameter roof vents are commercial size, therefore, are ideal in commercial settings. For those looking to ventilate their homes, please view roof vents with a smaller diameter.<\/p>\n

This 18 inch attic vent is suitable for installation in climate zones 1-3<\/a>. Air intake vents allow outside air to enter into attics and ventilation spaces.<\/p>\n

To determine the number of vents you may need for proper attic ventilation, see our Vent Calculator<\/a>.<\/p>\n

How it works<\/strong>:<\/h4>\n

The Air Intake Roof Louver provides fresh air into the attic or plenum.\u00a0 Without proper rooftop ventilation, heat and moisture may cause decay of the structure. This roof vent<\/a> also helps to keep insulation dry in the winter to prevent the growth of mold.<\/p>\n

Additionally, the round design is aerodynamic to withstand wind speeds up to 200 mph. The 18 inch Pop Vent is great for residential roof applications because of its low profile. It can also be painted to match the color<\/a> of the asphalt shingles.<\/p>\n

For any questions please see the\u00a0frequently asked questions page<\/a>. If you still have questions, email the sales team at\u00a0sales@roofvents.com<\/a>\u00a0or call 845-565-7770<\/p>\n

Pop Vents are UL Listed<\/a> and rated up to 50+ PSF or wind pressure above 200 MPH.\u00a0 Certified by Texas Department of Insurance<\/a>, Florida State Approved<\/a> & Conforms to the Standards of CALFIRE<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
