Product Summary
BCI® Joists are lighter weight offering long spans and best of all, strong floors that last. AJS I-joists have a solid-sawn flange, are high quality, high performance floor and roof joists available in the Eastern U.S. and Canada.
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.

Construction and Materials
Goodfellow offers a diverse range of lumber and engineered wood products designed for various construction and woodworking applications. Their product categories span from traditional hardwoods and softwoods to advanced engineered wood solutions like I-Joists and Glulam beams, as well as panel products such as MDF and Particleboard. They also provide specialty wood items, timbers, and treated lumber for specific project needs.
The construction and materials used in Goodfellow's lumber and engineered wood products vary significantly depending on the specific item. For instance:
- Hardwoods and Softwoods: These are typically solid wood materials sourced from various tree species, processed into standard lumber dimensions. Their construction involves cutting logs into planks and beams, which are then dried and graded for strength and quality. The materials are natural wood fibers, characterized by their grain patterns and inherent strength properties.
- Engineered Wood Products (I-Joists, Glulam): These products are manufactured by bonding together wood strands, veneers, or lumber pieces using adhesives.
- I-Joists are constructed with an 'I' shape, featuring flanges (typically made of solid lumber or laminated veneer lumber - LVL) and a web (made of oriented strand board - OSB or plywood). This design optimizes material use for high strength-to-weight ratios.
- Glued Laminated Timber (Glulam) is made by layering and bonding together dimension lumber with structural adhesives. This process creates large, strong structural members capable of spanning significant distances.
- Panel Products (MDF, Particleboard, OSB, Plywood): These are composite wood materials made by combining wood fibers, particles, or veneers with binders and pressure.
- MDF (Medium Density Fiberboard) is made from wood fibers combined with wax and resin binder, pressed into panels under high temperature and pressure.
- Particleboard is manufactured from wood particles (such as wood chips or sawdust) mixed with resin or other suitable binders, which are then pressed and extruded or cast.
- OSB (Oriented Strand Board) is constructed from cross-oriented layers of rectangular wood strands or wafers that are bonded together with adhesives using heat and pressure.
- Plywood is made by gluing together thin sheets of wood veneer, called plies or lamellas, with adjacent layers having their wood grain rotated up to 90 degrees to one another.
- Beams and Timbers: These can refer to solid sawn lumber or engineered wood products, depending on the specific application and material specification. They are designed for structural load-bearing purposes.
- Treated Lumber: This refers to lumber that has been chemically treated to resist decay, fungi, and insects. The construction involves pressure treating the wood with specific preservatives.
