Laminated veneer lumber (LVL) is a popular structural composite lumber that is found throughout the construction industry. LVL planks are typically stronger and more uniform than conventional milled lumber, thus making them preferable across a range of industrial construction applications. Made from wood options such as Douglas fir, LVL can function as headers, beams, trusses, joists, scaffolding walk boards, paneling, and more.

What Is Laminated Veneer Lumber (LVL)?

What Is Laminated Veneer Lumber (LVL)?

What is Laminated Veneer LumberLVL is manufactured through a rotary peeling procedure utilizing a lathe. The product is composed of layers of thin wood veneers joined together with durable, heavy-duty adhesives. As an engineered material, LVL offers high levels of uniformity and predictability both in sizing and composition. That reliability extends to performance as well. Manufacturers are able to individually test every wood veneer, making it possible to combine veneers with the desired properties to ensure an optimal final product.

Benefits of LVL

LVL is engineered with a strength that allows it to withstand greater weights and distance spans than traditional woods. However, while LVL stands out thanks to its impressive strength-to-weight ratio, it has an array of additional benefits that make it ideal for construction, particularly as compared to other building materials. LVL has none of the naturally occurring knots and other flaws commonly found in solid timber. This reliable consistency improves its durability. It is less likely that LVL will shrink or warp, making it a significantly safer option for scaffolding walkboards.

Prefabrication applications are ideal for LVL as this material offers flexibility and control in regard to its final design. Manufacturers can accurately predict the properties of the end product, and can shape it according to its intended application. Sizing is also flexible, as LVL does not depend on log size for its length. Other benefits of LVL include:

  • Low cost
  • Lightweight
  • Efficient use of resources

Specifically, LVL utilizes its wood fiber sustainably. Multiple varieties of wood fiber can make up the material, reducing overall waste and adding the benefits of versatility and environmental friendliness.

The consistency, strength, and sizing flexibility of LVL all give this lumber an advantage over other types of wood, particularly for demanding applications such as industrial scaffolding. Worker safety depends on walkboards that are strong and dependable. Added to that, LVL can address other safety concerns.

LVL Fire Resistance

Another advantageous feature of LVL is its resistance to fire. Rather than burning through initially, when LVL comes into contact with fire, its surface first chars. This char actually creates a defensive, insulating covering overtop the lumber’s surface, safeguarding the interior composition from immediate fire and heat damage. Structurally, this means that LVL will remain strong for longer and decelerate the progression of the fire.

LVL Mold and Rot Resistance

There are a few key factors when considering LVL’s resistance to rot or mold, including installation and finishes. First, while LVL is often an internal, structural building component, installing LVL during dry weather conditions is beneficial to prevent moisture absorption during the construction process itself. Also, sealants, resins, and added coatings or treatments will help shield LVL from the elements and decomposition. Generally, applying sealant to LVL surfaces creates a barrier for moisture and a longer life span for the material.
