TopShield® is the home of the one and only Whirlybird® Turbine Ventilator, the All Weather Turbine Vent. Whirlybird® turbines offer all of the essentials for energy savings and are geared toward going green. Wind turbines are available in two sizes— 12", and 14". The 14" Big Whirly turbine moves 37% more air than the 12". The 12" turbine is available in an aluminum finish.
TopShield® Whirlybird® turbines are also available in two models— internally or externally braced. While the internally and externally braced turbines both have the same internal construction, the externally braced turbines have three braces that surround the outside of the turbine.
