Laminated Strand Lumber Uses

They cut pine aspen and other soft woods into strands less than one foot long then pressure bond them using a waterproof adhesive.
Laminated strand lumber uses. Laminated strand lumber lsl lsl provides attributes such as high strength high stiffness and dimensional stability. Lsl simply defined is an engineered wood product used primarily as an alternative to traditional lumber and other engineered wood products like laminated veneer lumber lvl and glulam. By peeling apart fibre strand by strand we re able to piece it back together to optimize the structural properties of each piece of lumber. Laminated veneer lumber is an engineered wood product that uses multiple layers of thin wood assembled with adhesives.
Made in a factory under controlled specifications it is stronger straighter and more uniform. An overview what is laminated strand lumber lsl. In this report we focus on the average north american production of laminated strand lumber lsl. When cross bonded for increased stiffness it can be used to form wall and floor panels.
Laminated strand lumber is good for the environment and builders alike. Lvl is suitable for use as beams trusses planks and rafters. Long spans and heavily loaded beams are far easier and anytime you have ceilings over 10 tall laminated studs are the only way to go if you like straight walls. Lvl is a type of structural composite l.
What is lvl used for. The manufacturing process of lsl enables large members to be made from relatively small trees providing efficient utilization of forest resources. It is typically used for headers beams rimboard and edge forming material. Laminated strand lumber and oriented stand lumber 11 21 advantages and uses 11 21 standards and specifications 11 22 wood nonwood composite materials 11 22 inorganic bonded composite materials 11 23 wood thermoplastic composite materials 11 25 literature cited 11 26.
With complete control over the quality of each piece of lumber we can provide a superior product to suit the unique needs and budgets of builders. The variation of thermal conductivity for lsl with moisture content has not been reported previously. Wood resources inputs for lsl production are sourced from the northeast north central u s. All forms of engineered wood products have their places in today s buildings.
As part of a larger study of heat and mass transfer through hybrid cross laminated timber clt panels made from laminated strand lumber lsl and red spruce picea rubens sarg laminae the authors determined the through thickness thermal conductivity of multiple samples of both materials for use in modeling heat and mass transfer. And central canada regions. Lsl factories typically use soft fast growing wood in place of slow growth hardwoods. Due to its composite nature it is much less likely than conventional lumber to warp twist bow or shrink.
Research has covered nine major forest products including both structural and nonstructural uses and four major regions. Other products in this group include laminated strand lumber lsl and parallel strand lumber psl.
