Whirlyvent passive ventilator

Expel heat and moisture from your home all year round

Why do you need Whirlyvent?

Heat gathering in the roof cavity can become as hot as 60°C. This stifling air then travels down through the ceiling into the room below, creating a very uncomfortable environment inside your home.

In addition to heat, steam extracted from your bathroom by an exhaust fan settles directly in the ceiling cavity. This trapped moisture encourages the growth of mildew in the roof cavity which could lead to wood rot and possibly paint peeling from the ceiling.

How does the Whirlyvent work?

With a Whirlyvent air in the ceiling cavity is constantly circulated. This keeps the temperature down inside and distributes dry air throughout, ensuring your insulation stays fresh and dry. As hot air rises, the ventilator begins spinning in the slightest breeze. This acts like a heat pump expelling hot air.

How do I know it really works?

The revolutionary Whirlyvent is made in Australia and has been thoroughly tested by the CSIRO, and meets the Australian Standard (AS2050-1989). Even in the most severe storm conditions, scientists found rain failed to penetrate the unique rotational vent. And in simulated cyclonic conditions, Whirlyvent withstood a wind velocity far above the required standard for cyclone-proof products.
