Cor-Vent® is a passive roof ventilation system designed to help create airflow pathways within roof cavities. The range is engineered to support ventilation over fascia, pliable building membrane (sarking) and flashing systems to help reduce the risk of trapped moisture and condensation within roof spaces.

Why is roof ventilation important?

Roof ventilation helps support airflow through roof cavities, which can assist in reducing the build-up of heat, moisture and condensation within the roof space.

Can poor roof ventilation cause condensation?

Poor airflow within a roof cavity can contribute to condensation build-up, particularly when warm internal air meets cooler roof surfaces. Balanced ventilation pathways may help reduce this risk.

Does every roof need ventilation?

Ventilation requirements can vary depending on roof design, insulation, climate zone, roofing materials and building systems. Many modern roof systems benefit from considered airflow design to support moisture management and roof cavity performance.

Cor-Vent® Roof Ventilation

Q: What does passive roof ventilation mean?

Passive roof ventilation uses natural airflow movement rather than powered fans or mechanical systems. Cor-Vent® products are designed to help air move through the roof cavity using natural pressure and temperature differences.
