Features. LVL is stronger and more stable with a higher strength-to-weight ratio than conventional solid sawn lumber. Multiple pieces (typically used in pairs) can be fastened together to obtain greater thicknesses, resulting in greater strength to carry/support heavier loads. E Value (Modulus of Elasticity) = 1.9E or better.As per LVL span rule of thumb, the depth of the LVL beam should be 1/20th of span in inches and their width is 1/3 to 1/4 of the depth. If beam span is 22 feet in length, then their depth = (22 × 12) ÷ 20 = approx 14 inches and width is 14/3 = approx 4″. So, you would need something like 3-1/2″ × 14″ size of LVL beam for a 22 foot span.
