New Zealand houses and their roof spaces are becoming more airtight. Without proper management of indoor moisture, this can lead to a build-up of moisture and problems with mould.
BRANZ has developed a measurement procedure to estimate the airtightness of residential roof spaces and has tested it on three buildings.
This could be a useful tool to help determine roof ventilation requirements to avoid mould and moisture problems.
