Ventilation is very important for buildings and essential to remove stale air and replace your home or property with fresh air. Good ventilation also helps to:

  • Moderate temperatures
  • Reduce moisture
  • Stop condensation
  • Control impurities (particularly those nasties)
  • Remove odours Provide air movement

No one wants to be stuck relaxing, working or sleeping in a room with no air movement or unpleasant odours! Not pleasant to say the least or healthy for you and your loved ones.

There are different types of ventilation systems that are used in buildings. Which one is right for your home will depend on the use of the space, the number of occupants and the building requirements for your particular property.


Here are 3 common ventilation examples for you to consider:


Yes, believe it, one of the most effective means to ventilate any space comes from windows. We’ve all opened a window to either let a breeze in to cool a space, let odours/steam out or just for the comfort of a room. Unless you are living in a smog congested city or experiencing extreme weather conditions, natural ventilation remains the most effective solution to ventilate your home.


Exhaust or Extraction Fans

Areas that tend to get steamy (think bathrooms) or have short fast blasts of steam with odours (think kitchens) use this type of ventilation. There are many different types of exhaust fans offering varying choices around size, design and noise.

  • Common styles you will find include:
  • Wall-mounted Exhaust Fans
  • Exterior Exhaust Fans
  • Ceiling Mounted or overhead Exhaust Fans
  • Inline Exhaust Fans
  • Exhaust Fans including lights


Turbine Vents

We generally know them as whirlybirds. These systems are perched on top of a roof of a building and their function is to extract (via wind moving the turbine) the hot air in the cavity of your ceiling space.

These are most effective when in conjunction with vents (either in the eaves or in the ceiling of the house).


Act early & think ahead

When thinking of your project make sure to talk to your builder about the ventilation requirements and options so that your new space will not only look great but be comfortable and well ventilated.

One thing that always rang true was that the best ideas are worth nothing without good execution. Not to say the challenge of being able to communicate a great idea to others! Taking the steps to make it all happen can be tiring, challenging, but also oh so satisfying!
