‘Constructing Cavities for Wall Claddings’ release statement

The Department of Building and Housing is pleased to announce the release of a new guide Constructing Cavities for Wall Claddings. The guide will be available from mid-July 2006.

The practical and easy-to-follow guide explains drained and vented cavity construction for timberframed buildings, as described in the Acceptable Solution for Building Code Clause E2 External Moisture, E2/AS1. It is designed to help those involved in design, construction and weathertightness compliance understand cavities to help ensure buildings are well built and healthy.

Drained and vented cavities are an important component of weathertight construction for higher-risk situations. Recent science and research has identified ‘drainage’ and ‘drying’ of water as critical features of cavities. The guide outlines why cavities are important, the essential features of cavity construction and the correct materials to use. It is essential reading for anyone involved in light timber-framed construction.

The guide is published as guidance  information in accordance with section 175 of the Building Act.  It is in a handy A5 format and  contains coloured illustrations to demonstrate the steps to follow. The Constructing Cavities for Wall Claddings guide can be downloaded for free from the Department’s website at www.dbh.govt.nz Hard copies can be obtained from the Department by calling 0800 242 243.
