Attachment 2: Risk Matrix Approach considering Weathertightness and Durability
The risk matrix approach was developed in order to provide a rational basis for deciding on appropriate claddings as part of a new E2/AS1, and as a basis for determining the timber treatments quoted in B2/AS1.
This document brings together material on weathertightness and durability that has been used to develop a risk matrix approach that accounts for the relative merits of different approaches and details that contribute to improved weathertightness and durability.
Descriptions of the process developed are included together with details of its application.
