An Engineered Wood Product (EWP) is a construction component made of wood by gluing. Laminated Veneer Lumber (LVL) is made of a veneer-based material such as plywood. Laminated Strand Lumber (LSL), used to construct building frames, is manufactured by chipping wood with bark. The chips are dried and aired and then compressed into the desired shape. I-beams, manufactured in a process with many stages, are used as beams for base and intermediate floors in houses and as support structures in concrete moulds. CLT (cross laminated timber) is a massive wood construction product consisting of bonded single-layer panels arranged at right angles to one another. CLT can measure up to 2.95m in width and 16.00m in length.
