Typically an individual LVL ply or layer of veneer is 45mm to 65mm in thickness, and may be up to 1.2 meters wide and as much as 25 meters in length, depending on the size of the original tree. The example photograph of LVL boards used to form board-and-batten trim on a building exterior is from the above document. It canīe used for fascia, casings, corner boards, and most otherĮxterior trim, and is available in lengths from 8 to 24 feet.Īccording to Laminated Veneer Lumber, Overview īeing a homogenous and dimensionally stable building material, LVL can be used in both bearing and non-bearing walls, as planks, as beams, as headers, in door and window frames, sliding door rails, steps, as well as in the roof trusses of single-family houses and engineered building constructions such as swimming halls, sport halls, etc. Weight falls in between solid wood and hardboard. To cut, nail, and install, similar to a piece of plywood. Like LVL beams, LVL trim is dimensionally stable and is easy Of cross-laminated layers to minimize cupping. Such as water-resistant edge sealing and adding a couple To good use as a trim material (photo at left) with some minor modifications Widely used in beams and headers, LVL has also been put
This approach also permits construction of large structural beams from smaller-diameter and lower-lumber-grades of trees.Īs we illustrate in our LVL beam photographs (above) and as we also discuss at TRIM, EXTERIOR CHOICES, INSTALLATION:
īecause individual wood ingredient defects in a laminated wood product will not extend beyond a single layer or "veneer" of wood, the overall laminated product is stronger than a piece of lumber of the same dimensions sawn from an individual tree. Our LVL composition closeup photo shows how the ends of individual plies within a single LVL beam may overlap within the product. In our LVL beam photo (below left) you will see that a higher-capacity LVL beam may be constructed as a built-up beam using multiple individual members nailed or nailed and glued together. Multiple laminated veneer lumber beams can be assembled to provide greater strength to carry greater loads. Illustraged in our photographs of LVL beams in use at a Poughkeepsie NY Project, our example LVL beams are made of fifteen laminated wood plies. Laminated veneer lumber is an "engineered wood product", developed in the 1960's, is produced by gluing together layers of wood veneers with the wood grains in parallel.
