This ventilation system aids in cooling the roof and attic. Installing a ventilation system such as this, helps save money on electricity costs.
After
This ventilation system creates the Venturi effect drawing air out of the attic space. By cutting the ridge open 4" wide for an entire 60' distance creates the same opening space as approximately 25, 12" turbines on the roof. Another advantage is that the turbines are placed lower on the roof and not at the roof peak where trapped air is also removed with the ridge vent.
