Ventilation options for your roof - May 15th 2000



Question from: Ron
Langley, BC

Dear Shell,

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?

Thanks, Ron

Dear Ron,

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.

Itís just that easy.
