Whirlybird Bib12 Aluminum Turbine Roof Ventilator, 12 In.

The Lomanco Whirlybird BIB12 is a 12-inch aluminum turbine roof ventilator designed to improve attic ventilation and reduce energy bills. This turbine features a spinning design powered by natural wind energy to exhaust stale air from the attic. When installed properly, the Whirlybird turbine reduces energy bills and helps prevent winter ice buildup by maintaining consistent attic ventilation.

The turbine's 21 air-foil curved vanes with rolled edges are designed to deflect water, protecting your home from leaks while ventilation occurs. Its rigid spider-type construction is riveted at every connection and has been tested to withstand winds of 110 mph, ensuring reliable performance in severe weather conditions. The 100% rust-free all-aluminum construction resists corrosion and weathering for long-term durability.
