Challenging Aotearoa NZ to create a building system that delivers better outcomes for all

House built since 2000 are better insulated and have become more airtight and as older homes have been upgraded and had new components such as aluminium window frames and sheet lining materials installed, they have also become more airtight, creating higher levels of internal moisture than previously. This can adversely affect the building structure, internal finishes, furnishings, fittings and the health of building occupants.

Yet internal moisture can be controlled often without huge cost. It requires an understanding of why the moisture occurs, how it affects the indoor environment and how it can be managed. This book identifies the causes and provides some solutions to eliminate or effectively manage indoor moisture.
