General Information

As well as information that can be found on the above Supplier's websites, information about Timber & its use in construction can be found at the following:

Product Information

The below details information concerning the Government’s, the Building industry’s & the Timber industry’s response to a local pest known as the European House Borer. The insect’s larva is known to eat certain species of Pine.

The Government has brought out regulations – Agriculture & Related Resources Protection (European House Borer) Regulations 2006 – that restrict the movement of Pine in & out of special zones within Western Australia unless certain precautionary measures have been taken (e.g. it has been treated accordingly).

Furthermore, we understand that local councils will not be approving any housing developments that are located within these special zones unless all structural Pine used is properly treated.

Additionally, the Building Commission is advising that a proper interpretation of the Building Code of Australia (specifically AS 1684 Residential Timber Framed Construction) requires Pine to be treated where used for a structural application in a special zone. This obviously has consequences for Builders building under the requirements of their issued Building Licence.

Blue Pine – Wespine Blue™

The treated structural Pine that our company predominantly supplies is Wespine Blue™. This is a great product – it is a repellent & terminator (if eaten) of both borer & termite insects, is environmentally friendly, & comes with a 25 year ‘repair & replace’ guarantee from our Industry.

Wespine Blue™ – Re-treatment

Wespine & Osmose (the H2-F treatment supplier for Wespine) have both indicated that where a builder alters a treated member (e.g. cutting), the altered area should not require re-treatment in a given set of cases. Please see the attached Wespine Blue – FAQ for further information. However, where a member has been ripped or significantly planed then re-treatment may be required. Any change to a treated member that results in the exposure of a significant amount of untreated timber may require re-treating.

We currently stock an on-site re-treatment product for situations where a treated member has been altered & requires re treatment. The product comes in an easy to use spray can.

Benefits of using Timber

Timber is an exceptional building product from an environmental point of view. Its benefits include:

  • Sustainability: through reforestation, the generation of Timber fit for human use is a sustainable process. Every tree that is harvested in Australia is replaced. Australia’s plantations are currently expanding so more trees are getting planted than are being harvested.

  • Carbon neutral: because trees absorb CO2 as they grow & the carbon is stored in the Timber for life, Timber from sustainably managed forests is carbon neutral. This means that the carbon released into the atmosphere from all further processes in getting the Timber fit for use is outweighed by the carbon absorbed by the tree during growth. Because other building materials are net contributors to atmospheric carbon over their life, the use of Timber in construction can significantly reduce a dwelling’s carbon footprint.

  • Lowest Embodied Energy: Embodied Energy is the amount of energy required for a product’s complete lifecycle, which includes raw material extraction, transport, manufacture, installation, use & disposal. A tonne of brick requires about 4 times the amount of energy to produce sawn softwood Timber, concrete 5 times, glass 6 times, steel 24 times & aluminium 126 times.

  • Thermal properties: Timber has the best thermal insulation properties of any mainstream construction material. It is 5 times better than concrete, 10 times better than brick & 350 times better than steel.
