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.
Contents:
- Key Standard and guide for specifiers
- Factors influencing wood decay and the need for preservative treatment
- Specifying an appropriate preservative treatment
- Post-treatment
This Wood Information Sheet was reviewed in March 2021 and minor amendments were made.
