Wind Driven Ventilation

Wind Driven vents, commonly referred to as 'Whirly birds' are the best way to increase the effectiveness of your insulation.

 

They help remove built up heat in summer, significantly reducing your thermal mass. Contrary to popular belief, they can also be effective in winter too. When your house cools down over night, the outside air can be warmer by mid morning; a whirly bird will remove the cold air and replace it with the warmer, outside air.

 

As you may have deduced, this scenario isn't always the case, so we can also install interactive grills, that allow you to determine when you ventilate and when you don't!

Only $175 each, fully installed, including GST.
