Whirlybirds

  

Systems Building Maintenance have installed whirlybirds as a form of roof ventilation for many years, thus avoiding problems caused by heat and moisture in the roof.

  

Why is roof ventilation important?

Whatever the weather, roof ventilation is a key to controlling heat and moisture in the roof space.  In the warmer months, the roof space may often reach temperatures as high as 50ºc, and sometimes 60ºc Apart from the obvious overload to your air-conditioner, heat is radiated downwards, leaving living areas uncomfortable.  Of course ceiling insulation is helpful, but without ventilation even insulation is not as successful as it might otherwise be.

During the colder months, water vapour from showers and cooking is drawn into roof spaces and can condense to form up to 12 litres of moisture per day.  This can render insulation ineffective, cause mildew on walls and ceilings and contribute to a damp environment.

  

Systems Building Maintenance can provide you with a whirlybird, suited to your roof at very competitive prices.
