Engineered for consistent performance, TimberStrand® Laminated Strand Lumber (LSL) starts straight and stays straight. As a result, it’s one of the most innovative and versatile building products available — a suitable solution for a diverse range of applications such as tall walls, beams, rim board, sill plates and so much more. TimberStrand LSL is a green building solution as well. The manufacturing process combines technology and innovation to produce high-performing engineered lumber using small-diameter trees that are not strong or straight enough on their own to be of structural value as conventional sawn lumber products.
