Optimize Airflow in Your Attic

Proper ventilation helps prevent heat and moisture from building up in your attic. A cool and dry attic helps the roof last longer, prevent leaks from ice dams, and keep your home healthy and comfortable year-round.

VentSure® InFlow® Intake Vents work with exhaust ventilation to help improve airflow through the attic. They are an ideal solution for roofs without soffits or to use as supplemental intake on roofs requiring additional ventilation.

  • Outstanding airflow – Net free vent area* of 10 sq. in. per lineal foot
  • Flexible design – Pulls air from underneath when installed at the eave and pulls from above when installed mid-roof
  • Excellent performance – Durable construction for long-lasting performance

Alongside adequate exhaust ventilation, VentSure® InFlow® Intake Vents can complete a balanced ventilation setup and are an essential part of the Total Protection Roofing System®.

*Net free vent area corresponds to the ventilation area that is open to unrestricted air flow. Generally, 1 sq. ft. of net free vent area per 150 sq. ft. of attic space is needed, balanced between intake and exhaust vents.

Ventilation Requirements

In order to create a consistent flow of cool, dry air through your attic, you need to make sure the air has a way to come in and go out: intake and exhaust. It’s important there is a balance between the intake and exhaust ventilation to help ensure air flows smoothly and efficiently.
