Specifying externally exposed structural timber
In This Series
This Wood Information Sheet (WIS) looks at some of the factors to consider when specifying a desired service life for structural timbers that are to be exposed outdoors but not in contact with the ground.
This WIS addresses general principles of structural design only, giving an overview of the subject with signposts to more detailed sources that are listed at the end.
• Types of structures used externally
• Designing for exposed structural timber
• Specifying for desired service life
• Use classes and service classes
• Preservative treatment specification
• Large cross-sectional solid timber
• Engineered timber
• Staining and discolouration

With engineered timber becoming an increasingly prevalent component in construction, it is important for members of the construction industry to understand not only the benefits and properties of Engineered wood products, but also the different types.
With modified wood products being improved upon on a seemingly daily basis, this...
Recent advances in timber technology and engineering have expanded the potential of building with wood. The development of new products and component manufacturing has allowed the construction of longer spans, the erection of multi-storey timber frame buildings, the forming of compound curved surfaces, the volumetric prefabrication and modular systems and...
