Industrial
treated timber preservative
The Wood Protection Association - Industrial Wood Preservation Specification and Practice
The Wood Protection Association (WPA) has issued a new manual
which provides a comprehensive guide to the industrial
pre-treatment of solid timber and wood-based board and
engineered wood products with preservatives. The document was
prepared by industry experts with advice from BRE.
Dr Andrew Hughes, chairman of the WPA Technical Committee
commented, “The last time the association issued a fully revised
manual was 1999 and the new edition is the result of intense
work to bring the association’s advice to specifiers, treaters
and users of treated timber up to date.
The new manual is being released in electronic format for the
first time making it both more accessible and readily updated –
an important feature in an industry where changes in standards
and regulations are frequent. The PDF format makes navigating
through the text and finding what you are looking for much
easier.”
The new manual includes the association’s widely used Commodity
Specifications updated to the latest standards with the addition
of two new specifications covering preservative treatment of
wood-based board and engineered wood products and timber for
decks and associated structures. The specifications show which
preservative types are suitable for each application and
preservatives supplied by WPA member companies are listed with
details of their properties and suitability for each Use Class,
the new system of timber uses brought in through changes to
European standards in late 2006.
Dr Chris Coggins Director of the WPA said, “This manual is the
latest in the series of publications from the association in
electronic format making it possible to create a new
user-friendly style with links that take readers quickly to the
sections they need. We are already working to take the
user-friendly concept further by developing a website-style
system for treatment specifications without the need to look
through the manual in detail. This will make specification quick
and accurate while maintaining confidence that specifications
incorporate the full requirements of both WPA and British
Standard specifications”.
The manual is available to industry professionals and WPA
members as a free download from our website at
www.wood-protection.org or can be ordered on CD. The latter also
contains the old 1999 edition for reference. We are certain that
the manual will prove invaluable to users and specifiers of
preservative treatment as well as providing treaters with all
the information they need to produce treated timber in
accordance with specifications based on the manual”.
