Witches Hat Vent

A Passive Vent Designed for Flat Roofs

AVP's Commercial Witches Hat is a Passive Vent designed for flat roof ventilation. The witches hat vent has a seamless top, preventing water and snow entry. The internal louvers prevent insects, rodents or birds from entering. The witches hat ventilates the attic by letting out hot air in the summer and moisture in the winter. In addition, making this vent ideal for low sloped or flat roofs. The detachable head allows for easy installation on EPDM, PVC, TPO and other roof membranes. Constructed of heavy gauge, rust free aluminum.

To create ventilation for a flat roof you will need to circulate the air in the attic or plenum. Attic ventilation is important as it can help maintain the health of the building. Removing unwanted heat in the summer and excess moisture in the winter will help the life of the roof. This will also help the functionality and efficiency of the HVAC systems. Here at AVP, we have a vent for any roof pitch in all climate zones.
