Specifying externally exposed structural timber
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.
Contents:
• Types of structures used externally
• Designing for exposed structural timber
• Specifying for desired service life
• Use classes and service classes
