I-Joists / LVL
I-Joists are "I"-shaped engineered wood structural members that offer strength, versatility and economy for use in residential and light commercial applications. I-Joists are comprised of top and bottom flanges of various widths united with webs of various depths. The flanges resist common bending stresses, and the web provides outstanding shear performance.
I-Joists can be manufactured using solid sawn lumber or structural composite lumber for the flange components, and plywood or oriented strand board for the web. This versatility allows the I-Joist manufacturer to make the most efficient use of wood fiber resources in our region while producing products that consistently perform to known standards.
Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. It offers several advantages over typical milled lumber: it is stronger, straighter, and more uniform. It is much less likely than conventional lumber to warp, twist, bow or shrink due to its composite nature. Made in a factory under controlled specifications, LVL products allow users to reduce their onsite labor. LVLs are typically used for headers, beams, Rim Board, and edge-forming material.
Rim Board is designed to work in conjunction with a wood I-Joist system, filling the space between the sill plate and the bottom wawll plate or between the top plate and bottom plate in multi-floor construction. In addition to filling the void, a Rim Board is an integral structural component that transfers both lateral and vertical forces. To function properly, the Rim Board must match the depth of the framing members.
