Specifying wood-based panels for structural use
This Wood Information Sheet (WIS) covers the following wood-based panels intended for structural use: cement bonded particleboard, fibreboard, oriented strand board (OSB), resin bonded particleboard (also known as chipboard), plywood and solid wood panels.
Boards of these types, intended for use in construction, fall under the scope of the harmonised standard BS EN 13986 Wood-based panels for use in construction. Characteristics, evaluation of conformity and marking and must therefore carry a CE mark or UKCA mark. From January 2022, products placed on the market in Great Britain (England, Wales and Scotland) must carry the UKCA mark. In Northern Ireland, CE marking is required while slightly different marking arrangements are prescribed for GB suppliers only supplying Northern Ireland.
This WIS is an overview of the subject with signposts to more detailed sources that are listed at the end.
- UKCA and CE Marking
- Maintaining fitness for purpose
- Example specifications
This WIS was revised in June 2021 to take account of new marking arrangements for construction products following the UK's exit from the European Union. It includes updated information and references and revised on-product label examples.
Certain types of wood-based panels can be used in demanding exterior situations. However, they must be correctly specified, detailed, installed and maintained, in order to provide the desired performance and service life.
Exterior use covers a wide range of situations. They may be fully exposed to wetting by...
Bryan Woodley explores the history, current use and development of structural insulated panels.
Wood-based panel products are sheet materials that contain a significant amount of wood in the form of strips, veneers, chips, strands or fibres. The categories described in this Wood Information Sheet (WIS) are:
- Oriented strand board (OSB)
- Fibre building boards
Within each of the above...
