SMART-Vents are fully integrated ventilator panel as a result of Metro's dedication to world-class design first in an industry. Metro SMART-Vents are available for all Metro panel profiles and are formed from Shake, Shingle, Tile, Roman or COTTAGE-Shingle profiles incorporating baffled attic ventilation and are made from the same long-life steel and stone coating as Metro panels. SMART-Vents create a single, functional unit that integrates perfectly with the surrounding roof panels, eliminating labor-intensive flashing details. To reap the benefits of reduced labor and a clean smart looking roof, use Metro SMART-Vents along with the Metro roof system.
