During winter, whirlybirds work to remove excess humidity and dampness, preventing mould and bacteria growth. Installing a whirlybird is an inexpensive way to make your home more energy-efficient, ventilated, and free from odours and stale air.

What is the point of a whirlybird?

Do Whirlybirds Work? Whirlybirds allow the hot air and moisture that is trapped within your roof cavity to escape naturally. Whirlybirds also provide a high level of air quality for your home by preventing the build up of fumes, stale air and damaging condensation.

How much do whirlybirds help?

According to Solar Whiz a whirlybird can help to prevent heat transferring from air trapped in the roof cavity to the ceiling. This in turn may limit the extent to which your home can heat up and reduce reliance on your air conditioning system (if you have one) which could save you energy and money.
