Construction and Materials
Boise Cascade I-Joists are engineered wood products designed for a wide range of structural applications in residential and commercial construction. They offer superior strength, stability, and performance compared to traditional dimensional lumber.
Construction
- Boise Cascade I-Joists are constructed using a combination of solid sawn lumber flanges and wood structural panel webs.
- The flanges are typically made from kiln-dried dimensional lumber, providing the primary load-bearing capacity of the joist.
- The web is made from oriented strand board (OSB) or plywood, which resists shear forces and prevents buckling of the flanges.
- These components are joined together using advanced adhesive and pressing techniques, creating a strong and unified structural element.
- The manufacturing process ensures precise dimensions and consistent quality, leading to predictable performance in building applications.
Materials
- Flanges: Kiln-dried dimensional lumber (e.g., SPF - Spruce-Pine-Fir, Doug Fir-Larch)
- Web: Wood structural panels (OSB or plywood)
- Adhesives: Structural adhesives are used to bond the flanges and web, ensuring a durable and robust connection.
Features and Benefits
Boise Cascade I-Joists offer a superior alternative to traditional dimensional lumber for floors, roofs, and walls. Engineered for strength, consistency, and performance, these joists provide a reliable foundation for any building project.
Key Features:
- Engineered Strength: Boise Cascade I-Joists are manufactured with precision, combining strong solid sawn lumber flanges with an engineered wood web. This construction creates a joist that is significantly stronger and more stable than conventional lumber of the same size.
- Dimensional Stability: Unlike solid lumber, I-Joists are designed to resist warping, twisting, shrinking, and swelling. This inherent stability minimizes the potential for costly callbacks due to structural movement.
- Consistent Quality: Each I-Joist undergoes rigorous quality control during manufacturing, ensuring uniformity in size, strength, and performance. This predictability allows for more efficient planning and construction.
- Lighter Weight: I-Joists are lighter than comparable solid lumber, making them easier to handle, cut, and install on the job site. This can lead to faster construction times and reduced labor costs.
- Design Flexibility: The consistent dimensions and high strength-to-weight ratio of I-Joists provide greater design flexibility, allowing for longer spans and reduced bearing requirements. This opens up possibilities for open-concept living spaces and creative architectural designs.
- Pre-punched Knockouts: I-Joists often come with pre-punched knockouts in the web, simplifying the installation of electrical wiring, plumbing, and HVAC systems. This saves time and effort during the rough-in phase.
- Reduced Canopy Effect: The open web design of I-Joists minimizes the "canopy effect" often associated with solid lumber, where minor inconsistencies can lead to uneven flooring.
Benefits:
- Enhanced Structural Integrity: The engineered design provides superior load-carrying capacity and resistance to bending and deflection, ensuring a robust and durable structure.
- Reduced Material Waste: The consistent size and predictable performance of I-Joists minimize waste associated with irregular lumber.
- Faster Installation: Their lighter weight and ease of handling translate to quicker assembly and reduced labor requirements.
- Improved Interior Comfort: The dimensional stability and reduced deflection contribute to quieter floors and a more comfortable living environment.
- Cost-Effectiveness: While the initial cost may differ, the long-term benefits of reduced callbacks, faster construction, and material efficiency make I-Joists a cost-effective choice.
- Environmental Considerations: Manufactured using sustainably harvested wood resources, I-Joists contribute to responsible building practices.
Core Advantages:
- Unmatched Consistency and Strength: Experience a level of predictability and structural performance that solid lumber simply cannot match.
- Superior Dimensional Stability: Eliminate concerns about warping, twisting, and shrinking, leading to a more stable and reliable building envelope.
- Effortless Installation and Design Freedom: Enjoy the benefits of lighter weight, easier handling, and the ability to achieve longer spans and more open designs.

Product Summary
Construction and Materials
F.P. Supply offers a range of engineered wood products designed for structural applications. These products leverage advanced manufacturing processes to create high-performance building components.
The core of these engineered wood products involves combining wood strands, veneers, or lumber into a composite material. This process allows for the creation of structural members that can offer superior strength, stability, and consistency compared to traditional solid lumber. The specific construction method and materials vary depending on the type of engineered wood product.
I-Joists
F.P. Supply's I-joists are engineered structural members designed for floor and roof framing. They are constructed with two primary components:
- Flanges: Typically made from solid sawn lumber or laminated veneer lumber (LVL). These are the top and bottom horizontal members of the I-joist.
- Web: Composed of oriented strand board (OSB) or plywood. This vertical member connects the flanges and resists shear forces.
The "I" shape is crucial for efficient load distribution, providing excellent strength-to-weight ratios.
Laminated Veneer Lumber (LVL)
LVL is a versatile engineered wood product manufactured by bonding thin wood veneers together with an adhesive under heat and pressure. The veneers are all oriented in the same direction, parallel to the long axis of the product.
- Construction: Multiple layers of wood veneer are laminated together.
- Materials: Primarily Douglas Fir and Southern Yellow Pine species are used for their strength characteristics.
LVL is known for its high structural integrity and is often used for beams, headers, and as flange material for I-joists.
Parallel Strand Lumber (PSL)
PSL is an engineered structural lumber product made from long, continuous strands of wood veneer that are engineered and laminated together under pressure.
- Construction: Wood strands are sorted, aligned parallel to the long axis of the product, and bonded with a high-performance adhesive.
- Materials: Commonly manufactured from Douglas Fir and Aspen.
PSL offers exceptional strength, stability, and a visually appealing appearance, making it suitable for posts, beams, and headers.
Laminated Strand Lumber (LSL)
LSL is an engineered wood product made from wood strands that are much shorter than those used in PSL. The strands are oriented in multiple directions during the manufacturing process.
- Construction: Wood strands are manufactured and then oriented in multiple directions and bonded together with a resin under heat and pressure.
- Materials: Typically produced from Aspen, Poplar, or Maple species.
LSL is known for its strength, consistency, and resistance to warping and twisting, making it suitable for studs, rim boards, and other structural framing components.
Features and Benefits
F.P. Supply offers a comprehensive range of engineered wood products designed to meet the demanding requirements of modern construction. These advanced wood materials provide superior strength, stability, and performance compared to traditional lumber, making them ideal for a variety of structural applications.
Core Advantages:
- Enhanced Strength and Stability: Engineered wood products are manufactured under controlled conditions, resulting in consistent strength and dimensional stability. This minimizes warping, twisting, and shrinkage commonly associated with solid sawn lumber, leading to more predictable structural performance and reduced callbacks.
- Design Flexibility: The engineered nature of these products allows for longer spans, deeper profiles, and custom dimensions, providing architects and builders with greater design freedom and the ability to create innovative building solutions.
- Sustainability: Engineered wood products often utilize smaller, faster-growing trees and smaller wood pieces, maximizing the use of forest resources and contributing to sustainable forestry practices.
- Durability and Performance: These materials are engineered for long-term durability and resistance to environmental factors, ensuring the structural integrity of buildings for years to come.
