What is Laminated veneer lumber (LVL) Beam?

Laminated Veneer Lumber (LVL) is an engineered wood product made by bonding thin wood veneers together with high-strength adhesives. This process creates a strong material that is widely used in construction.

LVL is stronger and more resistant to decay than laminated beams. LVL consists of multiple layers of plywood that are glued together at 90 degree angles and have high strength and stiffness properties. It’s also less likely to twist or warp since the layers of wood are glued together. Additionally, LVL is more resistant to shrinkage and expansion. Overall, LVL is stronger and more resilient.

What is a LVL beam used for?

LVL (laminated veneer wood) beams are a structural product used in the construction of houses, commercial buildings, decks, porches, and many other types of structures. It is made by bonding multiple layers of veneer together in alternating directions, forming a sturdy, lightweight, and dimensionally stable structural beam.

It is widely used to carry and transfer loads from the roof or ceiling of a structure, as well as to support the weight of the second layer on the first layer. It is commonly used as a header, trimmer, and bridge member in floor and roof structures, and provides superior dimensional stability, strength, and nail grip compared to sawn timber.

Compared to traditional wood, its high strength to weight ratio allows for longer spans and greater load capacity, thereby reducing the number of required support structures. Therefore, LVL beams can save costs and provide additional design flexibility through the structural functions of the building.

Will the LVL beam rot or mold?

LVL has the same characteristics as other wood products, and if designed and installed correctly, LVL will not rot or mold. Avoid contact with water during and after construction. Sealing the ends and edges of the LVL will help ensure moisture penetration is prevented. If the LVL is exposed for a long period of time, then it needs to be treated with anticorrosion and applied with a protective coating. Following best practices for managing moisture in wood structures will protect the product from damage or rot.

How does LVL beam compare to other building materials?

LVL is a sturdy, highly predictable, and uniform wooden product that can be made from fast-growing trees that are not suitable for traditional solid sawn timber. Its consistency in quality simplifies the construction process and reduces waste on the construction site.

Many species can be interchanged without affecting performance. This effective utilization of wood fibers increases its environmental advantages and makes it an attractive alternative to materials with higher carbon strength. Like most wooden products, it is very suitable for prefabrication. As an engineering product, LVL is not prone to shrinkage or warping, and can span longer distances and support heavier loads than traditional wood.

Will LVL beams sag?

Yes, LVL (Laminated Veneer Lumber) beams will sag over time due to the natural properties of the wood. For example, a long LVL beam with only a few nails at the end attached to the house may sag over time due to the weight of the beam and any loads placed on it.

To help prevent LVL beams from sagging, be sure to provide secure and evenly spaced supports for the beams. This will help reduce the stress placed on the beam and can minimize sagging over time.

Additionally, regular inspection and maintenance of LVL beams is important to ensure they remain safe and properly tilted.
