Ventilation Options For Your RoofMay 15th 2000
We live in a townhouse complex consisting of upper and lower units, would it have a cooling benefit if we installed Whirly bird vents in place of static vents in our upper unit roofs?
Extra ventilation in the roof to vent the roof cavity is good to move more air in and out reducing the air temperature in the cavity. However the best would be to install a low profile electric power exhaust fan. These exhaust fans can be controlled by a thermostat as well as a humidistat to operate both summer and winter. Warm moist air is equally as important to exhaust during the winter months.
It's just that easy.
