Book excerpt: Wood is one of the traditional materials used in construction applications, and there is a wide range of engineered wood products available for construction. Engineered wood is a wood product derived from wood waste and byproducts such as sawdust from hardwoods and softwoods. Engineered wood types include particleboard, plywood, fiberboard, oriented strand board (OSB), laminated veneer lumber (LVL), glued laminated timber (GLT), and cross-laminated timber (CLT). This book provides a detailed introduction to the development history of engineering wood and its raw materials, applications, and advantages and disadvantages. It also compares different types of engineering wood and discusses modification of engineering wood, testing standards for mechanical properties of engineering wood, anti-corrosion, and degradation.
