    Default Which whirly bird should I buy?

    Our Brisbane home has suffered mould in recent wet times. Construction is brick veneer, two storey, with a tiled roof.
    I plan to fit two whirly birds to the roof to improve air movement.
    A quick look at Bunnings found several "whirly bird" products.

    I am seeking suggestions on what to use, what features to look for, perhaps what to avoid please?

    Thanks.

    I fitted normal WBs to my garage years ago. The reduction in heat and increased air flow was profound. I have posted details previously. WBs don't really pump air out, they are really a glorified hole in the roof. If I did it again and specifically in your case I'd consider the solar powered roof vents. Even a small one will move a lot of air. Your bigger problem is ensuring the air within your walls can vent up and out. Remember in order for air to flow out it has to flow in somewhere and that those inlets should be screened to stop wasps and bees nesting in your walls. 2c

    Are you sure the mould is not from a leaking roof?
    Do you have sarking under your tiles?
