OPTI-A112 – Adjustable 1 wing roof attic ventilator for sloped roof

The OPTI-A112 sloped roof attic vent design of 1 wing and 12″ opening allows for optimal ventilation of the attic. Openings shaped from the structure of the vent eliminate any need for long-term maintenance as well as eliminating any chance of birds or rodents gaining access. The anti-gust deflectors prevent the infiltration of the elements regardless of the wind direction. This vent gives the advantage of a cooler attic in the summer months and a drier one in the winter months. This unit extends the integrity of the structure, provides increased comfort indoors along with energy conservation. This static vent combined with the help of the wind produces a chimney effect. The air is exchanged continuously at a frequency of 134 ft ³/min for a surface area up to 825 sq. ft.
