Book Description
"Wood treated with chromated copper arsenate (CCA), commonly called "green-treated" wood, dominated the residential market for several decades and was sold at lumberyards under a variety of trade names. However, as the result of voluntary changes submitted by CCA registrants, labeling of CCA by the Environmental Protection Agency (EPA) now permits the product to be used primarily for industrial applications. Use of wood treated prior to 2004 is not affected by this change. This development has raised questions about the availability of CCA-treated wood and the properties of alternative types of treatments."

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.

Book Description
NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT-- OVERSTOCK SALE -- Significantly reduced list price Wood preservatives are generally grouped into two categories: preservatives used for in-place field (remedial)treatment and preservatives used for pressure treatments.A limitation of in-place treatments is that they cannot beforced deeply into the wood under pressure. However, theycan be applied into the center of large wooden membersvia treatment holes. These preservatives may be availableas liquids, rods, or pastes. Pressure-treated wood has muchdeeper and more uniform preservative penetration thanwood treated with other methods. The type of pressuretreated wood is often dependent on the requirements of thespecific application. To guide selection of pressure-treatedwood, the American Wood Protection Association developedUse Category System standards. Other preservative characteristics, such as color, odor, and surface oiliness may alsobe relevant. Guidelines for selection and application of fieldtreatments and for selection and specification of pressure-treated wood are provided in this document.

Book Description
British Columbia has a large wood veneer products industry, producing predominantly plywood and laminated-veneer lumber (LVL). However, the damage done by the mountain pine beetle (Dendroctonus ponderosae, MPB) infestation has reduced material recovery and made the British Columbia plywood mills lose market share and mill profit. This project investigated the technical feasibility and economic benefits of using phenol formaldehyde resins to treat mountain pine beetle-attacked lodgepole pine (Pinus contorta Dougl.) veneers and to produce high-performance, durable engineered wood products.--Document.
