whirlybird perth

Welcome to Whirlybird Perth!

A Whirlybird is a ventilation system that you would find on the roof of your home. Ventilation is a crucial element of roof insulation, but why you ask?

Why should I get a whirlybird?

In summer, roof space temperatures can go as high as 70°C. Without a whirlybird, the heat will remain in the roof and eventually will travel downwards into your home. This leads to you using your air conditioning more often and leads to an increase in your energy bills.

In winter, the lack of whirlybird ventilation will result in moisture build-up within your roof space. Moisture within your roof space will lead to your insulation becoming wet and soaked, it will also lead to mould and mildew.
