With a new monthly feature on its FAQ area, TRADA’s website can help with advice, practical examples and technical information to answer your questions and avoid costly mistakes. This month’s feature focusses on preservatives.


Preservative treatments can significantly extend the service life of construction timbers by providing an effective long-term protection against all forms of wood decay and insect attack.


There are several important issues to consider when selecting a preservative treatment, namely: the type and level of treatment required; in-service conditions; service factors; desired service life; and permeability and the natural durability of timber species.


Featuring ten of the construction industry’s most commonly asked preservative questions, and a handy ‘where can I get more help’ guide, TRADA’s FAQ area takes the ‘headache’ out of finding that elusive answer to your urgent question.


From specifying preservatives, to disposing of treated timber, explaining the difference between water-borne and solvent treatments, to the impact of preservatives on the weathering of timber – FAQ is the perfect starting point for anyone looking for a quick answer to their preservative problem.


This month’s featured question is: How do I decide whether a wood product requires preservative treatment?
