How many Windmasters are needed

The number of whirlybirds required to sufficiently ventilate a home can vary on a number of factors. These include the construction of the roof, the orientation of the home and the size of the roof space.
As a general rule of thumb, one wind-driven whirlybird is required for every 80m2 of roof space.  
On average, this means a 3×1 would require two whirlybirds, whilst a standard 4×2 would need three to four.

Ollie came round last Saturday morning to install our new roof vents. Very polite and was done in an hour. Very happy with the work and I'm sure they'll make a huge difference. Would be happy to recommend.
