Engineered wood’s surge in popularity through the years comes as no surprise to us. Willamette Valley Company is a leading supplier of wood products and custom solutions for engineered wood manufacturers and we are seeing an increase in demand for engineered wood products like never before. More and more architects and construction builders are embracing them for their economic advantages, construction quality, durability, sustainability, and aesthetics. There is an extensive range of engineered wood products we’ve written about in the past like Plywood and Cross Laminated Timber (CLT), however, we’re taking a closer look at Structural Composite Lumber (SCL) and in this post. Here are some frequently asked questions.

What is Structural Composite Lumber (SCL)?

Structural composite lumber is defined by the APA – The Engineered Wood Association as “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”.

What Are Examples of Structural Composite Lumber?

Some common examples of SCL include Laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL). 

-Laminated Veneer Lumber (LVL) is the most widely used of the structural composite lumber products and is often used in headers and beams, hip and valley rafters, scaffold planking and the flange material for prefabricated wood I-joists. 

-Parallel Strand Lumber (PSL) is frequently used as load-bearing columns. Like LVL and glulam, PSL is used for beam and header applications where high bending strength is needed.

-Laminated Strand Lumber (LSL) is used in a variety of applications from studs to millwork components.

-Oriented Strand Lumber (OSL) is made from flaked wood strands and also used in a variety of applications from studs to millwork components.

Why Do Builders Use SCL? 

There are a range of reasons why structural composite lumber  (SCL) products are an appealing choice, here are just a few. 

-Stability & Consistency. SCL is known by builders and architects for it’s solid, uniform properties and is virtually free from warping and splitting, making it ideal for a range of industrial uses and building projects. 

-Quality & Design Flexibility. The material’s high quality and design flexibility are also appealing qualities in the building and construction industry. 

-Cost Savings. SLC is not subject to the same price volatility found in solid lumber markets. 

Environmental Sustainability. SLC is sourced from sustainably managed North American forests and produces very little waste. It can be manufactured using small, fast-grow and underutilized trees, therefore representing an efficient use of forest resources. Another interesting fact: APA-trademarked SCL products are exempt from U.S. EPA and California formaldehyde regulations due to their very low emission rates.

What is SCL Used For?

SCL’s high quality and strength makes it a practical choice for rafters, headers, beams, joists, studs and columns. Typical uses for SCL are also

Upholstered furniture frame components
Wood furniture substrate
Case goods, shelving and retail displays
Door and window components
Recreational vehicles
Truck and trailer components
Bench and seat components
Engineered flooring substrate
Concrete form wales and bracing
Domestic and export crating and packaging
Substrate for counters, tables, pool tables, and bowling alleys

APA – The Engineered Wood Association Publishes New Engineered Wood Case Studies

WVCO is proud of its longstanding partnership with the APA – The Engineered Wood Association, a nonprofit trade association for engineered wood product manufacturers. APA represents approximately 150 mills throughout North America, ranging in size and structure. The association is considered the “Leading Resource for Information About Engineered Wood Products”.

This month, the organization published two new case studies illustrating the benefits of engineered wood and mass timber products. Both case studies are available as free downloads on the APA website, www.apawood.org.

Beauty and the Budget showcases Portland, Oregon, LEVER Architecture’s use of plywood and mass timber elements throughout the Flex building, a multi-purpose structure in Portland. In addition to exposed plywood for the shear walls, the LEVER team used exposed glulam beams throughout and glulam for the stairs as well.

“Innovative use of wood allows us to create powerful architecture even for projects with limited budgets,” architect George Michael Rusch said. “When you can use mass timber for its inherent structural properties, you can make buildings that speak volumes. It’s about the morality of the material.”

Mass Timber has Banks Seeing Green features the new First United Bank branches in Shawnee, Oklahoma, and Fredericksburg, Texas. Both the first mass timber structures in their states, these net-zero buildings were designed with engineered wood for economic and sustainability reasons.

“First United wanted buildings that really showed how they were built and related to their customer base,” according to Gensler project architect Taylor Coleman. “Using mass timber was the best way to accomplish those goals.”
