This Talking Timber seminar will travel along the path of timber as it is prepared for a career in the building industry.

Starting off in the forest, we will explore the influences on timber as it grows and how this will impact on its properties as sawn timber. Once felled, the timber starts its processing journey where it is again subject to many influences.

Once in its sawn forms – framing and wall cladding – we will then traverse the treatment options for the end use, drying, storage (during transport and on site), installation and post-installation care. For timber weatherboard claddings, we will cover the requirements for a good installation including storage and transport, defects, suitable species, treatment, applicable codes and standards, installation and fixing, as well as appropriate coatings for the treatment and finally maintenance.

Online registration is now available.

Topics the seminar will cover will include:

  • history of timber use
  • timber properties including:
      • influences on growing trees – root stock, pruning, wind, soils
      • sustainability, carbon sequestration
      • log characteristics – compression wood, corewood/outerwood, density, grain
      • moisture in newly sawn timber
      • shrinkage – when it occurs
    • minimising timber variation
    • certification
