International Beams LVL (laminated veneer lumber) typically comes in 1 ¾” thicknesses and is suitable for use as ledgers to support floor (or roof) framing. For example, IB LVL may be used to support an intermediate floor at balloon-framed walls, or it may be used to support floor framing when poured concrete foundation walls extend above the floor level.

There are situations where architectural geometric restrictions of the cornice detailing require that the attic ceiling/floor joist be cut at a slope to match the sloped rafters. The bearing and shear capacity can be seriously compromised with this type of sloped-end cut on an I-Joist. International Beams has tested sloped-end cuts on IB I-joists. As a result of these APA-witnessed tests, we have established maximum end reactions for unreinforced and reinforced sloped-end cuts.
