Industry Recognized
PERFORMANCE
Where LSL Works Best
Trusted by contractors, architects, and engineers, LSL is designed to perform in a wide range of applications:
Headers & Beams
Long spans and heavy loads handled with ease
Wall Studs & Tall Walls
Perfectly straight studs for flawless finishes that will hold up over time.
Rim Boards & Plates
Strong, uniform load transfer for solid floor systems.
Why Choose LSL?
LSL is prized by builders for several distinct advantages that lead to faster, more efficient, and higher-quality construction.
Highest Production
STANDARDS
Dimensional Stability
LSL is manufactured under controlled conditions, resulting in a product that resists shrinking, twisting, bowing, and checking better than traditional solid-sawn lumber. This “straight and true” nature reduces callbacks and installation labor.
High Strength-to-Weight Ratio
The engineered process packs significant structural strength into a relatively lighter product, making handling and installation easier while delivering excellent load-carrying capacity.
Consistent Quality
Unlike natural wood, which contains knots and defects, LSL has uniform density, strength, and stiffness along its entire length. This consistency simplifies engineering calculations and ensures predictable performance on site.
Sustainable Sourcing
LSL often utilizes fast-growing, less expensive tree species (like aspen or poplar) or smaller timber that cannot be used for traditional lumber. This optimizes resource use and supports sustainable forest management.
Long Lengths Available
LSL can be manufactured in continuous billets up to 60 feet long, reducing the need for splices in large projects like long headers or beams, which simplifies construction.
Typical Specifications and Dimensions
LSL is manufactured to stringent industry standards (typically meeting requirements outlined by the International Code Council Evaluation Service – ICC-ES).
Maximum Length
Depending on the manufacturing facility, LSL is commonly available in lengths up to 48 feet, and sometimes up to 64 feet for specialty orders.
Moisture Content
LSL typically has a lower, more controlled moisture content than conventional lumber (often around 8-10% at the time of manufacture), contributing significantly to its dimensional stability.
Performance Characteristics
Performance in engineered wood products is measured primarily by strength (stress) and stiffness (deflection).
