New Zealand’s wooden homes are rich collectors of moisture and mould. Too much moisture is bad for respiratory health, and it encourages dust mites, which are linked to allergies and asthma.
About 45% of New Zealand homes have moisture-related problems. High moisture levels can be caused by condensation, dampness and built up steam from activities like cooking and showering.
Good ventilation is important to beating moisture, as damp homes are hard to heat – moisture absorbs heat energy before the temperature can rise.
Regularly opening the windows helps ventilate your home in all areas. However the bathroom and kitchen commonly need extra ventilation. An extractor fan can be the easy answer to ventilation in these areas.
You can also install a ventilation system that naturally encourages fresh, clean air through your home. Look for a system that includes a heat exchanger, which draws fresh, clean air through your home, rather than using air from the roof cavity, which is often filled with contaminants.
A good ventilation system does not substitute for insulation, heating, or damp fixing systems. All four systems are needed for a warmer and healthier home for you and your family.
