Twista Whirlybird


Create a more comfortable environment in your home with our innovative roof vents. Effectively manage the temperature in your roof cavity without having to rely on expensive air-conditioning.

Your roof cavity can reach as much as 70 degrees Celsius in summer. This heat is then radiated throughout your ceiling and walls creating uncomfortable conditions throughout every room in your house.

By increasing ventilation and extracting heated air throughout your roof cavity, roof whirlybirds provide a simple solution which 'you have to feel it to believe it'.

Benefits In Winter

Have you ever stopped to consider, when you turn on your exhaust fans in your kitchen and bathrooms, where does that moist air go? If your roof cavity does not have an effective ventilation system it can become a horribly moist and stale environment that is conducive to mould growth. This mould can then spread and thrive throughout your bathroom, kitchen and living areas.

Installing roof whirlybirds is an effective way of increasing airflow throughout your roof cavity.

Even though it might seem like you are getting excellent value for money thanks to the initial low cost, you will pay in the long run due to weak performance and potential for malfunction. There are a lot of ceiling cavities in Sydney that have been ruined due to leaking whirligigs imported from dodgy manufacturers.
