Description
BRANZ research into material corrosion rates in various positions on a building envelope has made a surprising discovery that will help in material specification and maintenance.
There are two micro-environments typically found around the building envelope, defined by NZS 3604:2011 Timber-framed buildings as sheltered and exposed. A previous research article in Build 154, Nailing micro-environments, identified that these two environments differ both from each other and from that of the surrounding atmosphere.
As such, materials may perform differently depending on their position on the building envelope.
Currently, there is no comprehensive comparative data on how materials perform and the factors contributing to material performance in sheltered and exposed micro-environments.
