Talking Timber seminar

The focus of this Talking Timber seminar is understanding the properties of timber and then applying this to the design and construction of timber framed and clad buildings. To ensure these products are effectively used by designers and constructors they must understand the properties of wood and how those properties are maintained and enhanced.













This Timber Topics 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 the 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.    

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

  • applicable Code clauses (B1, B2, E2,) and standards (NZS 3604:2011, NZS 3602:2003, NZS 3640:2003)
  • framing including:

            - impacts on performance

            - species, durability, treatment options and hazard classes 

            - benefits of kiln drying

            - grades and marking

            - moisture content (and correctly measuring this)

            - installation

            - permitted defects

            - care on site

  • cladding including:

             - reported cladding issues

             - durability – treatment options and hazard classes 

             - species – radiata pine, cedar, redwood

             - profiles and samples

             - vertical versus horizontal 

             - finger jointed versus clears

             - moisture content

             - timber surface finishes

             - coating options

             - care and handling on site

             - installation

             - maintenance

  • new developments.
