Book Description
The effective and lasting treatment of wood against insect and fungal attack grows in importance as forestry reserves decline and as cost increases feed through to the building trade and other timber users. At the same time, environmental pressures bear ever more heavily on the types of chemicals and processes employed in the preservation industry. This book records the proceedings of an international meeting arranged to address such issues. The 15 principal chapters are based upon papers by invited experts to a combined audience of preservation practitioners and non-specialists. The chapter sequence follows the logical pattern of the conference, beginning with a review of the biological threats to be contended. There follow historical and state-of-the-art accounts of aqueous, organic solvent and non-liquid treatment processes. Preservatives increasingly must meet international product and environmental standards, which along with the related test, analytical and quality control procedures, are described and referenced. Contributors from the wood preservation industry address a range of needs associated with cost, safety and performance efficacy, not neglecting a search for a better understanding of the finer chemical mechanisms involved. Remaining problems are outlined in strategies for further research and development. - Address a range of needs associated with cost, safety and performance efficacy - Problems are outlined in strategies for further research and development

Book Description
Note from the publisher: Now in its sixth edition, this bestselling reference focuses on the basic materials and methods used in building construction. Emphasizing common construction systems such as light wood frame, masonry bearing wall, steel frame, and reinforced concrete construction, the new edition includes new information on building materials properties; the latest on "pre-engineered" building components and sustainability issues; and reflects the latest building codes and standards. It also features an expanded series of case studies along with more axonometric detail drawings and revised photographs for a thoroughly illustrated approach.

Book Description
Wood products used in exterior applications must be protected against biodeterioration. Traditionally, wood products used CCA or the older inexpensive organic biocides, but environmental, disposal and governmental regulations have resulted in a rapid and dramatic worldwide shift. This book covers the many steps involved in developing a wood preservative and gives overviews on modified wood, wood deterioration, worldwide trends in wood protections, and mold in homes.

Book Description
For decades chromated copper arsenate (CCA) was the primary preservative for treated wood used in residential construction. However, recent label changes submitted by CCA registrants will withdraw CCA from most residential applications. This action has increased interest in arsenic free preservative systems that have been standardized by the American Wood Preservers? Association. These include acid copper chromate (ACC), alkaline copper quat (ACQ), copper azole (CBA-A and CA-B), copper citrate (CC), copper dimethyldithio-carbamate (CDDC), and copper HDO (CX-A). All of these CCA alternatives rely on copper as their primary biocide, although some have co-biocides to help prevent attack by copper-tolerant fungi. These alternative treatments have appearance and handling properties‍?similar to those of CCA and are likely to be readily accepted by consumers. Prior studies indicate that these treatments release preservative components into the environment at a rate greater than or equal to that of CCA, but because their components have lower mammalian toxicity they are less likely to cause concern in residential applications. As the treated wood industry evolves, it is probable that a wider range of types and retentions of wood preservatives will become available, with the treatment more closely tailored to a specific type of construction application.
