Bradford WindMaster BAL is the bushfire rated version of the WindMaster wind driven roof ventilator, 300 mm, in 24 colour options. No electricity, no running costs.
Why a BAL version exists
A roof ventilator is a deliberate opening in the roof. In a bushfire that opening is an ember path straight into the roof space, which is one of the most common ways houses are lost. The BAL version is built and tested so the roof can be ventilated without creating that path. On a site with a BAL rating, the standard version is not an equivalent product.
Ventilation still needs an inlet
Air has to enter the roof space for any extractor to move air out of it. Plan the eave or soffit inlets with the ventilator, and check that those inlets also suit the bushfire rating.
What it does
Reduces heat load in summer and lowers the risk of condensation in the roof space year round. Fits most metal and tiled roofs.
