What do whirlybirds really do for your home? During the long hot summer days in Australia moisture and warm air become trapped in your ceiling void, (attic) heating your home and causing moisture to accumulate in your ceiling space.

Moisture in your roof can be the cause of not only uncomfortable living conditions but can cause mould, mildew and dry rot in your roof space.

If you have air conditioners running at the same time they will be overworking and cooling your home inefficiently as a consequence.

It can seem like there is no easy solution when you’re uncomfortable in your own home but a Whirlybird can and will make a difference by moving the hot air out and cycling cooler air in through your eve vents.

How do they work?

As we all know hot air rises so the Whirlybird is installed as close as possible to the ridgeline on your roof.

This is where the hot air is trapped and installing the Whirlybird here allows the hot air to escape and in turn lets the ceiling void to cool down.

The Whirlybird also allows fresh air to circulate in your ceiling void (attic) preventing the build-up of moisture condensation and in extending the life of your roof.
