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
Pacific Woodtech is the premier manufacturer of engineered wood products.
Construction and Materials
Pacific Woodtech offers a range of engineered wood products designed for structural applications. Their product lines include treated/coated lumber, I-joists, and Laminated Veneer Lumber (LVL).
Product Construction and Materials
The specific construction and materials used can vary across Pacific Woodtech's engineered wood product categories. Generally, these products are manufactured using wood fibers, veneers, or solid lumber that are bonded together with adhesives. The manufacturing process involves precisely engineering wood components to achieve enhanced strength, stability, and consistency compared to traditional solid sawn lumber.
Treated/Coated Lumber
- This category typically involves lumber that has undergone a treatment process.
- Treatments are often applied to enhance durability, resistance to decay, and protection against insect damage.
- Coating processes can also be used for surface protection and improved aesthetic qualities.
- The base material is typically softwood lumber.
Engineered - I-Joist
- Pacific Woodtech's I-joists are structural members designed for floor and roof framing.
- They are constructed from two primary components:
- Flanges: These are typically made from solid sawn lumber or laminated veneer lumber (LVL).
- Webs: These are usually made from oriented strand board (OSB) or plywood.
- The components are bonded together using structural adhesives to create a strong, lightweight, and dimensionally stable joist.
- The "I" shape provides excellent strength-to-weight ratio.
Engineered - LVL (Laminated Veneer Lumber)
- LVL is an engineered wood product manufactured from multiple layers of thin wood veneer bonded together with durable adhesives.
- The veneers are typically rotary peeled from logs and are all oriented to lie flat and run in the same direction parallel to the long dimension of the product.
- This consistent grain structure provides exceptional strength and uniformity.
- LVL is commonly used for beams, headers, columns, and rim board.
- It offers superior strength, stiffness, and stability compared to solid sawn lumber of equivalent size.
Features and Benefits
Pacific Woodtech offers high-performance engineered wood products designed to meet the evolving needs of the construction industry. Focusing on innovation and quality, Pacific Woodtech provides solutions that enhance structural integrity, design flexibility, and construction efficiency.
