Specification and use of wood-based panels in exterior and high humidity situations
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 salt or fresh water or be more protected with a risk of occasional wetting, such as soffits under porches or lorry decks.
This Wood Information Sheet details the considerations which must be made when specifying wood-based panels for exterior use, in particular whether a preservative treatment or protective measure is required to extend service life.
- Exterior exposure
- Factors affecting performance
- Durability of wood-based panels
- Durability of plywood
- Design and workmanship
- CE and UKCA marking
This Wood Information Sheet was revised in January 2021 following an extensive restructure. Reworked contents include: durability of plywood, use class 2 and treatments.
With its aesthetic appeal, thermal insulation, acoustic properties and resistance to the chemicals frequently used in swimming pools timber represents a straightforward choice for swimming pool construction. Despite its suitability for swimming pool construction, there are still a number of considerations to be made when specifying timber for the job....
PanelGuide V4 gives information on the properties, applications and end uses of all the main types of wood-based panel:
- medium density fibreboard (MDF)
- fibreboard (hardboard, mediumboard, softboard)
- oriented strand board (OSB)
- particleboard (chipboard, flaxboard, cement-bonded particleboard)
- plywood (including blockboard and laminboard).
This interactive PDF is aimed at construction professionals (specifiers, designers,...
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...
