PreVent ventilators from Metallic Products are a headache-free — and energy efficient — way to encourage healthy airflow for your metal buildings. These built-to-last building accessories are lightweight, made of 16- or 24-gauge Galvalume, and work in conjunction with standard closures and ridge caps. With no moving parts to wear out, and their ability to adapt to a variety of roofing systems, they make for versatile roof ventilation with no maintenance required.

PreVent ventilators offer big benefits to your steel buildings, too. A low profile allows them to blend seamlessly with virtually any look. Meanwhile, their leak- and snow-proof nature keeps your structures protected from the damaging effects of moisture — including infiltration from wind-driven rain. The prevent ventilator is a worthwhile investment to help improve airflow, ensure maximum comfort and better protect your metal buildings.
