The WANZ Guide to Window Installation as described in E2/AS1 Amendment 7                       
The objective of this document is an attempt to offer a better understanding of window and door installation as described in E2/AS1 Amendment 7.

The details and drawings used within E2/AS1 to describe window and door installation are two dimensional, cross sectional details which show a required end result. However, often a more in-depth sequential approach might describe the process better to the end user. This is what WANZ have attempted to do with this document by providing a step by step guide to the details offered by this latest version of the Compliance Document E2/AS1.

This edition of the guide has added details pertaining to the installation of full height windows and doors pushed up to the soffit lining.

E2 VM1 (Amendment 5 Clause 1.5.3) requires that all previous Verified Solutions (such as WANZ WIS) be retested to amendment 5 as of 1 July 2013. WANZ has  chosen not to re-test WANZ WIS as the E2 Amendment 5 and subsequent amendments addresses all of the previous concerns thus making WANZ WIS redundant.
