Pine
The use of Australian Pine is by far the most popular timber in frames. The timber has been kiln dried and sized to give a uniform product that will not shrink or warp alolowing for use in most situations.
CCA Treated Pine
CCA treated pine has been treated with copper chrome arsenate. This treatment stops fungi and other timber pests and diseases from attacking and is used where there is a known problem with subterranean pests.
LOSP Treated Pine
LOSP (Light Organic Solvent Preservatives) is another treatment that deters pests and diseases. The major advantages of LOSP treatment lie in the fact that the dimensional stability of the timber is unaltered, so all manufacturing processes can be carried out before treatment, eliminating the need to dispose of treated waste materials. Additionally the timber is ready for use as soon as the solvent in the treatment process has evaporated, with no need for post treatment drying. The relatively small cost of treating the frame gives the home owner the confidence of knowing that their home has protection from attack by wood-destroying insects & decay.
