What is engineered lumber?
Engineered lumber products are fabricated wood pieces used to improve upon the normal capabilities of construction lumber. These products are composed of wood particles (veneer, wood chips, oriented strands, wafers, laminated dimensional lumber, and combinations Thereof) bonded by long-lasting adhesives to ensure the structural integrity. Engineered lumber is available in both structural and architectural (appearance) grades that maintain physical uniformity and longevity.
Examples of engineered lumber
I-Beams,LVL's,Glue Lams, and Rim-Boards are a few examples of engineered lumber. You can see some more examples of engineered lumber by clicking here.
How is engineered lumber made?
Although the major manufacturers of engineered lumber have their own unique production methods, most engineered wood is made by thoroughly mixing wood fiber and wood flour with heated thermoplastic resin. This raw material is then extruded or injection molded into the desired shape.
During manufacturing, engineered lumber is able to be molded and shaped to meet nearly any design or specification. For example, engineered lumber can be bent and fixed to form stronger arching curves.
What makes engineered lumber sustainable?
Considered a “green” or sustainable material, engineered lumber can be constructed from recycled plastics or waste products from wood processing.
I-Beams are strong, lightweight, "I" shaped engineered wood structural members that meet demanding performance standards. I-joists are comprised of top and bottom flanges, which resist bending, united with webs, which provide outstanding shear resistance. The flange material is typically laminated veneer lumber (LVL) or solid sawn lumber, and the web is made with plywood or OSB. The robust combination of structural characteristics results in a versatile, economical framing member that is easy to install in residential and light commercial projects.
