LSL and OSL offer good fastener-holding strength and mechanical connector performance and are commonly used in a variety of applications, such as beams, headers, studs, rim boards, and millwork components. Combined with an adhesive, the strands are oriented and formed into a large mat or billet and pressed. LSL and OSL are manufactured from flaked wood strands that have a high length-to-thickness ratio. These LSLs are 24′ long and are used to make this curved wall and will not warp or bow. Laminated Strand Lumber (LSL) and Oriented Strand Lumber (OSL) LVL is a member of the structural composite lumber (SCL) family of engineered wood products that are commonly used in the same structural applications as conventional sawn lumber and timber, including rafters, headers, beams, joists, rim boards, studs and columns. The resulting product features enhanced mechanical properties and dimensional stability that offer a broader range in product width, depth and length than conventional lumber. The grain of all veneers in the LVL billet is parallel to the long direction.
LVL is produced by bonding thin wood veneers together in a large billet. Illustraged in our photographs of LVL beams in use at a Poughkeepsie NY Project, our example. Laminated veneer lumber is an 'engineered wood product', developed in the 1960s, is produced by gluing together layers of wood veneers with the wood grains in parallel. Below are types of engineered wood being manufactured: Laminated Veneer Lumber (LVL) Definition & Characteristics of 'LVL' - Laminated Veneer Lumber, Beams, Headers. Engineered lumber provides all three, making it a solid choice for worry-free walls. Meeting the engineering and aesthetic demands of today’s homes, with their tall, window-filled walls, requires strength, straightness and stability from headers and studs.
