Use an LVL beam to eliminate twisting and splitting for quiet floors. The logs are debarked, pressure steamed with a mix of water vapor and chemicals for 48-hours, and then run through a veneer peeler that unrolls the log into a continuous sheet with a thickness between 1/16 and 1/4. The stacks then pass into a machine that produces high heat and pressure to ensure a strong, long-lasting adhesive bond between layers. If you size a roof beam like a structural ridge that has a L/240 limitation, you would multiply the minimum E-value by 0.666 (785,000 x 0.666 = 522,810 in this case).

Laminated veneer lumber or LVL is much look like plywood, generally made of thin sheets of wood which are sandwiched and bound with super stronger glue. So be careful when you compare products. Covers any span and every load with pin point accuracy. The span of a beam is determined by its depth, breadth, and typical construction factors including building width, loads, number of stories, joist spacing, etc. For example: A 20 foot long LVL beam should be 12 inches deep (2012) 20 = 12 inches). Due to lathe checks running perpendicular to the grain, the loose side of the veneer has several small fractures. And even though span tables provide limited data, they are very long. Although all possible efforts have been made to ensure that the information from this tool is accurate, the CWC cannot guarantee the completeness, accuracy or exactness of the information.
