Glulam In Australia
Australia has a long history of timber buildings
Glulam has been a part of that history for many years and has been used on some very unique projects.
• In Europe and North America there exists:
• A cultural attitude towards a preference for timber in both
structural and non-structural uses.
• Climatic conditions that forces sporting activities indoors
• There is an established and recognised third party certification
schemes providing the customer with confidence in both the
image of the industry and the quality of Glulam.
• No similar scheme existed in Australia prior to the
establishment of the GLTAA.
Glulam In Australia
• In 1989 The Glue Laminated Timber Association of
Australia (GLTAA) was formed
• The GLTAA set Industry Standards and implemented
a code of practice
• The GLTAA quality mark ensures designers and
builders they can rely on the Glulam product to
perform to specification.

Architect: BCC City Projects OfficeEngineer: AURECON (formerly Connell Wagner) National Award Sustainable Projects – Australian Institute of Project Management The use of deep section laminated timber beams was identified very early in the design process as a means of providing an efficient and low maintenance structural system to span over the salt water laden indoor pool enclosures.
CSIRO Aquaculture Architect: Architectus
Engineer: Bligh Tanner• Avoidance of steel in the marine environment• Robustness/longevity/low maintenance• Flexibility for future alteration• Low embodied energy
High Strength to weight with added aesthetic appearance
