This Guide explains how lightweight and mass timber buildings can be designed and built to manage heat, air, and moisture effectively, preventing condensation and supporting durable, high-performing construction. It provides practical, NCC-aligned guidance, recommended levels of moisture control, and verified building envelope solutions for four key Australian climate zones.
Introduction
This guide provides practical guidance on understanding and managing condensation in building projects, with a focus on timber construction. Condensation, if not properly addressed, can impact the durability of building materials, indoor air quality, and occupant health. This document outlines the science behind condensation, key moisture management principles, relevant building code requirements, and practical strategies for controlling moisture during construction. Whether you are designing, specifying, or building with timber, this guide is intended to help you make informed decisions to ensure safe, durable, and high-performing buildings.
