Why does wood need to be treated?

Most timber is susceptible, to varying degrees, to biological degradation from various hazards such as heat, moisture and insect attack.

In the context of building products it is reasonable to expect that, subject to normal maintenance, the product will last for a specified number of years.

Therefore timber needs to be treated to prevent degredation.
