New BRANZ resources and publications


BRANZ Research Now - Positional Corrosion

Two new Research Now fact sheets have been published in the area of positional corrosion:

  1. Positional corrosion 1: Impacts of natural elements on different parts of the building envelope; and
  2. How different micro-environments around a building envelope affect material corrosion.


Design Decisions

The new guide called Design Decisions has been published. This resource focuses on the key elements of design rather than getting into specific details of the relative merits of a design feature or building material or component. It can be used as a check to ensure all relevant factors have been considered during the design of a building and also as a basis for discussions with clients about the design of their building. The cost of this publication is $50.
