Whirly Bird Ventilator

The roof cavity of your home can get very hot under the summer sun. A Whirly Bird ventilator can help cool the roof cavity by pushing the hot air out, reducing the pressure on roof insulation to manage that roof cavity heat.

One ventilator should be provided per 50m2 of floor area. These types of ventilators generally only work when there is substantial wind. If it is a hot still day they are not as effective.

Whirly Bird Ventilators save approximately 5% on cooling energy according to the FirstRate5.0 Energy rating program.  This saves approximately $6 per year on cooling costs for a new home and $12 for a ten year old home.
