Optimize Airflow in your Attic

VentSure® 4-Foot Strip Heat & Moisture Ridge Vents work with VentSure® InFlow® intake vents and/or undereave soffit vents to help improve air flow through the attic. They are flexible enough to conform to virtually any roof slope, and their unique baffle design improves airflow by keeping leaves, pine needles or similar debris from impacting the performance of the vent.

  • Outstanding performance – net free vent area** of 20 sq. in. per lineal foot
  • Excellent versatility – patent-pending corrugated ridge design and alignment tabs allow for additional flexibility and strength to accommodate virtually any roof pitch, resulting in a strong uniform ridgeline
  • Roof durability – proper ventilation helps maximize the performance of the entire roof system

As a key component of a VentSure® Balanced Air Ventilation System, the VentSure® 4-Foot Strip Heat & Moisture Ridge Vent is an essential part of the Total Protection Roofing System®^.

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.
