Defined as wood which has been treated with a chemical, biological or physical agent to enhance its performance, modified wood products (MWPs) are an area of almost constant change, with new techniques being developed all the time.
The seemingly unrelenting changes and improvements in MWPs make the need for specifiers to be kept abreast of developments of paramount importance.
This Wood Information Sheet provides readers with a guide to the benefits of modifying wood, how to select and specify modified woods for a particular use and how woods are modified and the significance of specifiers.
Modified wood has been treated with a chemical, biological or physical agent to enhance its performance but does not contain a biocide.
One of the main drivers for wood modification is to improve the decay resistance of low durability timber species.
The three principal processes for modifying wood are: thermal modification, chemical modification and impregnation.
