Includes product descriptions and specification recommendations for structural composite lumber. SCL Publications Engineered Wood Construction Guide: Structural Composite Lumber ExcerptĮxcerpt from the Engineered Wood Construction Guide, Form E30. The mark signifies that product quality is subject to verification through APA audit-a procedure designed to assure manufacture in conformance with APA performance standards or the standard shown in the mark. Roseburg RigidLam LVL (Laminated Veneer Lumber) beams, headers, columns and studs provide a better alternative to traditional. which come into play when stick framing roofs. Another added benefit of LVL's is that they can come in almost unlimited lengths. These thicker sections readily nest into 2x4 or 2圆 framed walls as headers or columns.ģ/4" to 3-1/2" thick depths and lengths to match the end use.ĪPA trademarks appear only on products manufactured by APA member mills. MICROLLAM LVL BEAM BENEFITS: Uniform and predictable Resists warping, splitting and shrinking while supporting heavy loads Dimensionally stable Available. If you are looking for something 3 1/2' wide, such as a header, then you make want to look into LSL's which are usually a little bit cheaper but don't have quite the strength of an LVL. Two or three sections of SCL can be joined together to form 3-1/2-inch or 5-1/4-inch members. Typical uses for SCL include rafters, headers, beams, joists, studs, columns and I-joist flange material. SCL is a solid, highly predictable and uniform engineered wood product that is sawn to consistent sizes and is virtually free from warping and splitting. Definition & Characteristics of 'LVL' - Laminated Veneer Lumber, Beams, Headers. The resulting products out-perform conventional lumber when either face- or edge-loaded. In SCL billets, the grain of each layer of veneer or flakes runs primarily in the same direction. Whether you are creating a new opening in a load-bearing wall or just widening an existing opening, your work will require the addition of a header or beam. Structural composite lumber (SCL), which includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL), is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture-resistant adhesive into blocks of material known as billets, which are subsequently resawn into specified sizes. Placing the beam below the existing ceiling joists is a method that’s pretty straight forward. LVL beams are stronger and stiffer than normal lumber because LVLs are engineered so that strength-reducing characteristics, such as knots, slope and grain, are.
