What Is Structural Lumber? 

Structural lumber is wood used in projects that require high strength values. This heavy timber is minimally two or more inches thick and four or more inches wide. Its moisture content should be around 20% or less. 

Structural lumber manufacturers typically use softwood lumber to engineer this product. Common examples of tree species they use include: 

  • Southern Yellow Pine 
  • Douglas Fir 
  • Ponderosa Pine 
  • Western Red Cedar 
  • White Fir 

There are several structural grades of lumber and classifications when exploring structural lumber products, such as: 

  • Finger-jointed 
  • Light framing 
  • Machine Stress-Rated (MSR) 
  • Structural joists and planks 
  • Structural light framing 
  • Stud 
  • Structural joists and planks 
  • Timbers 

Within these classifications, there are also various types of structural lumber, such as: 

  • Laminated Strand Lumber (LSL) 
  • Laminated Veneer Lumber (LVL) 
  • Parallel Strand Lumber (PSL) 
  • Oriented Strand Lumber (OSL)

Deck Framing with Owens Corning Structural Lumber 

Owens Corning has reinvented structural lumber to last longer and better withstand the elements. Their building materials are superior to other structural lumber products available. With different sizes and colors, Owens Corning structural lumber is one of the most popular options for deck framing. 

Since Owens Corning structural lumber isn’t classic wood but instead an engineered material, you can avoid the rotting and warping inevitable when using standard lumber. By using Owens Corning, you are investing in the future of your project, ensuring its use for years to come.

Benefits of Owens Corning Structural Lumber

Using Owens Corning structural lumber for your deck, dock, or boardwalk has many benefits. Let’s explore them. 

Strength and Durability 

The experts at Owens Corning designed their lumber products with durability in mind. The lumber has Advantex® Fiberglas™, a corrosion-resistant technology that strengthens and adds durability to the lumber. 

Consistent Stability 

Traditional wood expands and contracts over time due to the elements, causing once beautifully laid deck boards to move with the substructure. This shift can happen much more quickly than you may expect. 

With Owens Corning lumber, the synthetic makeup ensures that your project does not expand and contract with the weather. Installing a premium product like Owens Corning guarantees your project’s look over time, and your deck boards will remain straight. 


Unlike wood, Owens Corning is rotproof. Each piece of lumber from Owens Corning is moisture-resistant and protects against pests and termites.  


Owens Corning lumber also has rustproof protection. It can come in contact with water (both salt and fresh) and ground without rusting. 

Complication Free 

Whether you’re a professional builder or embarking on a DIY project, Owens Corning structural lumber comes without complications. You can use this synthetic alternative in various projects without any hassle. 

Easy to Install 

Structural lumber from Owens Corning cuts into flat, uniform boards and installs just like traditional wood. Even with modest woodworking experience, you’ll find this structural wood easy to install. 

Thermal Resistant 

Structural composite lumber by Owens Corning has a low expansion and contraction design. It also has heat-reflective technology to make the wood thermal resistant. 


Owens Corning sets ambitious eco-friendly targets to ensure the company remains sustainable. Their goal is to limit the number of deck framing boards in landfills. 

In 2023, Ethisphere recognized the company as one of the world’s most ethical companies for the sixth consecutive year. It is only one of two construction and building materials companies to receive the honor.

Owens Corning WearDeck 

In 2022, Owens Corning acquired WearDeck, a premier composite decking producer in North America for commercial and residential uses. WearDeck manufactures its products from high-density polyethylene (HDPE) to be weather-resistant, long-lasting, durable, and strong. 

This gives WearDeck’s product a higher mechanical performance and lower maintenance cost than conventional composite decking options. 

Composite Decking 

Composite decking is an engineered wood product made of various parts or substances. Manufacturers make composite materials by combining natural and synthetic ingredients. Typically, composite deck boards combine the following: 

  • Chemical additives 
  • Plastic (virgin or recycled) 
  • Wood fiber
