Retrofit ventilation roof.

A perfect replacement for whirlybirds roof wind turbines which frequently slow down or stop turning all together because of corrosion damage or just wear and tear. Achieving calculated continuous and unimpeded airflow through the roof cavity is relatively straight forward. Our systems can be adapted to the existing roof s structural support system to provide long term life expectancy and reduced life cycle costs while also enhancing the property s curb appeal. Aura solar fans are a perfect replacement for turbine vent heads.

When installing roof tile vents on the front and rear sides of a roof some staggering in height and horizontal positioning should ideally take place to prevent wind tunneling. A minimum ventilation gap of 25mm is to be provided over the loft insulation to allow sufficient ventilation at the eaves.
