This BRANZ Answers seminar gives answers to a wide range of practical questions relating to new ways of doing things in the residential building and construction industry. We cover new types of buildings, new types of products and systems, new ways to increase the performance of buildings, and various regulatory changes.

When designing junctions, we need to consider the situation or context that the junctions are in, the appropriate materials we need to use, and the best design practices. This module covers geographical location; suitable materials; designing flashings and penetrations; designing for maintenance.

Using case studies for a simple house and a complex house, this module illustrates the design of a variety of junctions and the issues to consider.

A junction is where materials meet or change direction and can be a weakness in the weathertightness of the building envelope. This module covers how water behaves; why junctions are important; the different types of junctions. 

This module provides an introduction to junction installation for LBPs. It covers what junctions are and why they are important; how water behaves; flashings, penetrations, sealants, and sequencing; what you need to know before you start building; and common issues and problems during installation.

This book aims to provide background to the issues and contributing factors and guidance on the principles of weathertight construction - how water behaves and how we deal with it.

This guide focuses on the ‘good’ design, specification and construction requirements for all types of waterproof decks and balconies (Building Code, structure, substrate, membrane and walk-on surface) to residential buildings (stand-alone houses, townhouses, apartments and so on) to ensure such decks will be serviceable over the life of the building.

There are two compliance paths for waterproof decks – Acceptable Solution E2/AS1 and specific design. This guide focuses on E2/AS1.

This Good Practice Guide will be an essential reference tool for all those involved in the selection, design or construction of waterproof decks.

Note that membranes must be applied by certified contractors or approved applicators, and this guide is not intended as a how-to guide for inexperienced or non-approved applicators to apply membranes.
