Q.   Why should timber be preservative-treated?

A.   Timber is a renewable and economic building material that is harvested and processed from sustainably managed forests. However, untreated wood may be subject to attack by insects, including termites, marine borers, and decay fungi. It may also slowly deteriorate when exposed to the weather. This is especially important in hot and humid climates or wherever wood comes into contact with ground or water.

To ensure structural soundness and long service life therefore, wood must be protected. Preservative treatment provides this protection and gives the users of timber with a longer-lasting product by extending the service life and the useful life of structures, indoors or outdoors.
