Glulam vs. LVL: A Comprehensive Guide to Engineered Wood Selection
When it comes to building structures, wood has long been a popular choice due to its versatility, strength, and aesthetic appeal. Two commonly used engineered wood products in the construction industry are Glulam (glued laminated timber) and LVL (laminated veneer lumber). In this blog post, we will explore the characteristics, benefits, and applications of Glulam and LVL, helping you make an informed decision for your next construction project.
Glulam: Strength and Beauty Combined
Glulam is a structural engineered wood product made by bonding multiple layers of dimensioned lumber together with durable adhesives. The result is a strong and aesthetically pleasing material that combines the natural beauty of wood with exceptional strength and stability. Glulam beams are commonly used in a variety of construction projects, including residential, commercial, and industrial applications.

Benefits of Glulam
- Superior Strength: Glulam offers high strength and stiffness, making it capable of withstanding heavy loads and providing long-span capabilities. It is particularly well-suited for applications that require large open spaces without the need for supporting columns or walls.
- Design Flexibility: Glulam’s manufacturing process allows for the creation of custom shapes and sizes, making it a versatile option for architects and designers. It can be curved, arched, or shaped into complex forms, enabling innovative and eye-catching architectural designs.
- Environmental Sustainability: Glulam is an eco-friendly choice as it utilizes renewable wood resources and requires less energy to produce compared to other building materials. It also sequesters carbon dioxide, helping mitigate the environmental impact of construction projects.
LVL: Strength and Consistency
LVL, like Glulam, is an engineered wood product that consists of multiple layers of thin wood veneers glued together. However, unlike Glulam, LVL is typically manufactured from rotary-peeled or sliced wood veneers. This manufacturing process produces a strong, dimensionally stable, and uniform material.
Benefits of LVL
- Uniformity: LVL offers consistent properties throughout the entire length and width of the product. This uniformity makes it an excellent choice for applications where predictable performance is crucial, such as beams, headers, and studs.
- High Load-Bearing Capacity: LVL boasts excellent strength and load-bearing capacity, making it suitable for heavy-duty applications. It can withstand substantial vertical and horizontal loads, making it ideal for structural elements requiring reliable support.
- Resistance to Shrinkage and Warping: Due to its manufacturing process, LVL experiences minimal shrinkage, warping, or twisting. This dimensional stability ensures the structural integrity of the wood product over time, reducing the risk of issues related to settlement or movement.
Choosing Between Glulam and LVL
The decision between Glulam and LVL depends on various factors, including project requirements, design considerations, and budget constraints. Here are a few guidelines to consider:
- Span and Load Requirements: Glulam excels in long-span applications and heavy-load situations. If your project demands wide spans or needs to support substantial loads without intermediate supports, Glulam might be the preferred choice.
- Consistency and Predictability: LVL’s uniform properties make it an excellent option for applications where consistent performance is crucial, such as engineered beams and headers.
- Architectural Design: If your project requires custom shapes, curves, or unique architectural features, Glulam’s flexibility in manufacturing allows for greater design possibilities.
Conclusion
Glulam and LVL are both excellent choices when it comes to engineered wood products. Glulam offers superior strength and design flexibility, making it ideal for long spans and architectural innovations.
