Important information for owners


Modern building materials and construction methods mean that new homes are more air-tight and have less natural ventilation than older homes. And our modern lifestyles, with two income families, longer working and commuting times, and greater concerns about home security, noise and privacy mean that homes are closed up much more than in the past.

Poor ventilation in new homes can cause a rapid build up of moisture which can damage curtains, wall coverings, windows and carpets. Mould, mildew and dust mites thrive in poorly ventilated homes leading to a higher risk of asthma, allergies and respiratory problems. And 'off-gassing' of the chemicals used in modern building materials coupled with poor ventilation can also affect overall health and well-being.


According to BRANZ, moisture is best removed from homes by both continuous ventilation and adequate heating, thus preventing condensation, mould and mildew.

Most new homes now include heating and cooling systems to keep them comfortable, security systems to protect them, dishwashers and automatic garage doors etc. Features that were optional extras five years ago are now standard in most new home designs. But what about your home's indoor air quality and ventilation needs?

A healthy indoor environment and regular supply of fresh clean air is at least as important for your family and your home as a dishwasher or vacuum cleaner!
