Changes in the forest resource have shifted building materials away from sawn wood to engineered composite products to make more efficient use of our forest resources. Properties of these new products are different from those of sawn wood products, especially with regard to their response to moisture and biodeterioration. Wood protection systems are needed for engineered composite products to improve their durability, but new environmentally friendly organic biocides are vulnerable to inactivation from heat needed for the manufacture of composite products. New types of delivery systems are needed that not only protect the biocide from the heat of the fabrication process but also slowly release the biocide during the service life of the product. An inert nanocarrier delivery system, such as clay nanotubules, may be able to protect the biocide from the heating process and release biocide over a long period of time.
