Tall Vents are not new to the market. There are many installations where Tall Vents are the best solution to achieve proper attic ventilation. Tall Vents can be installed slightly above the roof line, creating a high point to maximize the exchange of warm, moist air from the attic to the exterior of the building. There is an increasing trend in roof design where ridge lines are minimized, and Tall vents are the only way to achieve proper "balanced" ventilation. In climates with high accumulations of snow, Tall Vents keep the exhaust above the snow, improving their operation year round. The design and construction of Tall Vents have continued to evolve, with the Duraflo ProTurbo, ProVentilator and ProGooseneck vents offering a series of innovative, next generation products. Duraflo tall vents are designed with a proven, functionally superior, internal baffle system, high-grade polypropylene construction, and maintenance-free design.
