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
