Guide to the specification, installation and use of preservative treated engineered wood products
This user-friendly guide provides information on best practices for the selection, preservative treatment, design, installation and finishing of Engineered Wood Products (EWP) to ensure product fitness for purpose and performance over a range of applications, hazard exposures, and design lives. The target users are designers, builders, engineers, specifiers and other users of EWPs.
In the guide, EWPs are defined as structural timber composites formed from various timber or wood components in combination with adhesives, including glued-laminated timber, laminated veneer lumber (LVL), plywood, oriented-strand board (OSB), particleboard and I-beams. Nail-plated beams and trusses, and medium density fibreboard are considered outside the scope of this document. Other products such as parallel strand lumber and laminated strand lumber are not generally available in Australia and are also not covered.
The guide is intended to operate as an industry application document in conjunction with the suite of relevant Australian Standards and the Building Code of Australia (BCA).
