WIS 2/3-16 Preservative treatment for timber: a guide to specification

The first decision to be made regarding preservative treatment is whether the use of a naturally durable species will satisfy the durability requirements or whether treatment is needed. This Wood Information Sheet aims to guide the specifier through the process necessary to reach a decision that will result in a timber component that is fit for purpose.

Aspects considered include service factors, desired service life, the in-service environment, natural durability and regulated products.

This Wood Information Sheet (WIS) guides the specifier through the process of: 

  • Deciding whether a preservative treatment is required to protect a timber product
  • Specifying where a treatment is required
  • Specifying an appropriate treatment to ensure that a timber component is fit for purpose with regards to its durability.
