Design for durability

Regardless of the durability qualities of a material type, it is important for the designer to consider the level of maintenance, repair or replacement that may be required within the design life of the structure.

Designing durable timber structures includes an assessment of the building material properties and preservative treatments that may be applied to those materials. It also includes an assessment of potential service hazards that may impact on the timber building elements.

This design guide provides guidance on the durability of timber in a wide range of applications. Not every application is considered, as some are not appropriate for timber use.
