External membranes and Building Code compliance

Codewords 38 (June 2009 by the Department of Building and Housing) includes an article that discusses how to establish compliance with Clause E2 External Moisture of the New Zealand Building Code, particularly in relation to external membranes for roofs and decks. The article was developed in response to variations in building consent authority (BCA) approaches to this issue and can be downloaded at www.dbh.govt.nz/codewords-38-4.

The article refers to NZS 3604:1999.
