The cost of Parallam beams is a paramount consideration in construction projects. Notably, the price per unit volume of Parallam PSL beams is significantly higher than that of high-grade plywood, with treated PSL beams commanding a 5.6-fold premium.
This disparity is likely attributed to the limited production and distribution volumes of PSL beams, making them a specialized product with elevated manufacturing and logistics costs. To ensure competitiveness and reasonableness, it’s crucial to validate prices with multiple suppliers.
Parallam’s exceptional strength enables it to support longer spans and open floor plans, but pricing depends on the specific application, supplier, and market.
What is the Typical Cost Range for Parallam Beams Compared to Glu-laminated Columns?
Among the various types of lumber, Parallam beams and glu-laminated columns are two popular choices that offer distinct benefits. However, they differ in terms of cost, and it’s essential to understand the typical price range to make an informed decision.
Parallam beams, also known as laminated veneer lumber (LVL), are made by layering wood veneers in different directions to create a strong and stable beam. This process produces a product that is renowned for its high strength-to-weight ratio, allowing architects and builders to create complex designs while minimizing the use of materials. As for glu-laminated columns, they are constructed by gluing together layers of lumber to form a solid column. The result is a sturdy and reliable column that can withstand the rigors of heavy loads and harsh weather conditions.
In terms of cost, Parallam beams tend to be more expensive than glu-laminated columns due to the complex manufacturing process involved in producing LVL. The cost of Parallam beams can range from $1 to $5 per board foot, depending on the size and grade of the lumber. Glu-laminated columns, on the other hand, can cost anywhere from 50 cents to $3 per board foot, depending on the size and type of lumber used. However, it’s essential to note that the cost of both products can vary significantly depending on the supplier, location, and other factors.
Can I Use Parallam Beams for Exposed Applications, and How Do They Fare in Terms of Weather Resistance?
Are you wondering if you can use Parallam beams for exposed applications, and how they hold up against the elements? Let’s dive into the details.
Parallam beams are engineered wood products made from oriented strand board (OSB) and are often used in construction for their strength, durability, and sustainability. When it comes to exposed applications, such as exterior walls, decking, or flooring, Parallam beams can be a viable option. However, their performance in these situations depends on several factors, including the type of finish, painting, and coating, as well as the climate and environmental conditions.
In terms of weather resistance, Parallam beams are designed to withstand various types of weather, including rain, snow, wind, and sunlight. They are resistant to rot, decay, and insect damage, making them a suitable choice for outdoor applications. However, it’s essential to note that Parallam beams can be affected by extreme weather conditions, such as high winds or flooding, which can cause warping, splitting, or other forms of damage.
To ensure optimal performance, it’s recommended to properly finish and protect the Parallam beams during installation. This can include applying a coat of paint or stain, sealing the edges, and ensuring proper drainage. Additionally, following the manufacturer’s guidelines and recommendations for installation and maintenance will help to maximize the lifespan and weather resistance of the Parallam beams.

- Type of finish and coating
- Climate and environmental conditions
- Proper installation and maintenance
What Are Some Key Differences between Parallam and Trus Joist Engineered Wood Products?
While both products are designed to provide the strength and durability of traditional wood, they differ in terms of their composition, applications, and performance. To start, Parallam is a laminated veneer lumber (LVL) that is made by layering thin sheets of wood veneer to create a solid, yet lightweight, beam. This unique construction allows Parallam to offer exceptional resistance to warping and twisting, making it an excellent choice for applications where stability is crucial.
In contrast, Trus Joist is a type of engineered wood that is specifically designed for use as a floor joist. While it is also made from layers of wood veneer, the wood fibers in Trus Joist are arranged in a different pattern, providing improved structural integrity and load-carrying capacity. This makes Trus Joist particularly well-suited for use in floor systems, where it can help to distribute heavy loads and provide a solid foundation for the structure above.
One key difference between Parallam and Trus Joist is their intended use. Parallam is often used in load-bearing applications, such as beams and headers, where its exceptional strength and stability are particularly valuable. Trus Joist, on the other hand, is designed for use in floor and roof systems, where its improved load-carrying capacity and structural integrity are essential. Additionally, the material specifications and tolerances for the two products differ, with Parallam requiring more stringent tolerances due to its use in high-stress applications. This means that Trus Joist may be more suitable for use in residential construction, where the loads are typically lower and the tolerances are more relaxed.
What Are the Primary Advantages of Parallam Beams in Terms of Structural Integrity and Load Capacity?
Parallam beams offer several significant advantages in terms of structural integrity and load capacity. One of the most notable benefits is their exceptional strength-to-weight ratio. This means that Parallam beams are able to support heavy loads while maintaining a relatively low weight, making them an ideal choice for construction projects where weight is a concern.
Another significant advantage of Parallam beams is their resistance to warping and twisting. This is due to their unique parallel laminate structure, which provides excellent rigidity and stability. As a result, Parallam beams are less susceptible to damage from environmental factors such as temperature changes and humidity, making them a reliable choice for projects that require consistent performance.
