| Homes often have small air gaps between the living space and the attic. If you have a whirlybird turbine vent on the roof, on windy days the turbine can suck air out of your living area, into the attic, and then outside. In the summer full ventilation is desirable, but in the winter less attic venilation is necessary. The Turbine Boss will reduce wintertime heat loss through the turbine vent during the winter.
The Turbine Boss inserts inside the turbine vent. It has a thermostatic controller that will automatically open the damper's louvers when the attic temperature reaches 80 degrees Fahrenheit, and close the louvers when the temperature drops to 40 degrees Fahrenheit. Using the "Winter Air Flow Selector", the louvers may be set so they only close by 55% to 80%, still allowing sufficient ventilating on cold days. No batteries or wiring is required.
To install, remove the set screws on your existing turbine vent and remove the turbine head. Place the Turbine Boss inside the tube, and then re-attach the turbine head. Once installed, you'll never have to cover your turbine vent again. It is suitable for both 12 and 14 inch diameter turbine vents.
