Laminated veneer lumber is an engaged wood product that use 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 the onsite labor. They are typically used for headers, beams, rimboards, and edge-forming material.
