Construction and Materials
Boise Cascade's engineered wood products, specifically their Glued Laminated Timber (Glulam), represent a high-performance and sustainable building material. Glulam is manufactured by bonding together individual pieces of dimension lumber with strong, durable adhesives.
The construction process involves selecting kiln-dried softwood lumber, which is then graded for its structural properties. This lumber is end-jointed to create long, continuous members. These individual laminations are then precisely spread with a structural adhesive and assembled under pressure and heat in hydraulic presses. This controlled process ensures a strong, homogeneous, and reliable structural member that is stronger and stiffer than solid sawn lumber of the same dimensions.
Materials Used:
- Lumber: Kiln-dried softwood lumber, typically Douglas Fir-Larch or Southern Pine, is the primary raw material. The wood is carefully selected and graded to meet stringent structural requirements.
- Adhesives: High-strength structural adhesives, such as phenol resorcinol or melamine-urea formaldehyde, are used to bond the laminations. These adhesives are designed to withstand long-term structural loads and environmental exposure.
The resulting Glulam beams are custom-manufactured to precise project specifications, allowing for a wide range of shapes and sizes. This makes them suitable for a variety of structural applications, including beams, columns, headers, and trusses. Their engineered nature allows for greater design flexibility and the ability to span longer distances compared to traditional wood framing.
Features and Benefits
Boise Cascade Glulam beams are a superior choice for structural applications, offering a robust and aesthetically pleasing alternative to traditional dimensional lumber or steel. Engineered from select kiln-dried dimension lumber, carefully bonded together with high-strength adhesives, these beams provide exceptional load-carrying capacity and dimensional stability.
Key Features and Benefits:
- High Strength-to-Weight Ratio: Glulam beams are engineered to deliver impressive structural performance while being lighter than steel beams of comparable strength. This translates to easier handling, transportation, and installation, potentially reducing labor costs and project timelines.
- Dimensional Stability: Unlike solid sawn lumber, which can warp, twist, and shrink, Glulam is manufactured with seasoned lumber and bonded under controlled conditions. This inherent stability minimizes movement due to changes in moisture content, ensuring long-term structural integrity and reducing the risk of cracking or joint separation in surrounding materials.
- Design Flexibility: Glulam beams can be manufactured in a wide range of depths, widths, and lengths, allowing for custom solutions tailored to specific project requirements. This adaptability makes them suitable for diverse architectural designs, from residential applications to large commercial and industrial structures.
- Aesthetic Appeal: Available in various appearance grades, Glulam offers a natural, warm, and attractive finish that can be left exposed for a visually stunning architectural element. This eliminates the need for additional cladding in many designs, saving on material and labor costs.
- Sustainable Material: Glulam is produced from renewable resources, making it an environmentally conscious building material.
- Durability: When properly specified and protected, Glulam offers excellent durability and longevity.
Core Advantages:
- Exceptional Structural Performance: Glulam's engineered nature allows it to reliably support significant loads, making it ideal for a wide range of structural applications.
- Cost-Effectiveness: The combination of reduced labor for installation, potential for less material needed due to design flexibility, and aesthetic appeal can contribute to overall project cost savings.
- Design Freedom: Architects and builders can achieve unique and complex structural forms with Glulam, pushing the boundaries of traditional design.

Product Summary
Construction and Materials
The onCENTER Blue Linx Engineered Products line offers a range of engineered wood solutions designed for robust framing applications. These products are crafted from wood, a natural and renewable resource, processed to achieve superior strength, stability, and consistency compared to traditional lumber. Key product types within the onCENTER Blue Linx range include: * Framing Lumber: This category encompasses standard dimensional lumber that has been engineered for improved performance. The manufacturing process often involves kiln-drying and precise grading to ensure uniformity in size and strength. * I-Joists: Engineered I-joists are characterized by their distinctive "I" shape. They are constructed with a top and bottom flange made of solid sawn lumber or laminated veneer lumber (LVL), connected by a web made of oriented strand board (OSB) or plywood. This design provides an excellent strength-to-weight ratio, allowing for longer spans and reduced floor or roof system depth. The flanges carry the bending stress, while the web resists shear forces. * LVL (Laminated Veneer Lumber): LVL is an engineered wood product made by bonding together multiple layers of thin wood veneers. These veneers are typically rotary cut and then typically oriented in the same direction. The resulting product offers exceptional strength and stability, making it ideal for applications such as beams, headers, and posts where high load-bearing capacity is required. LVL is resistant to warping, shrinking, and splitting. * Glulam (Glued Laminated Timber): Glulam beams are structural members produced by bonding together individual pieces of lumber with structural adhesives. The lumber strands are carefully selected and graded, and then laminated with their strong faces placed together. This process creates beams that are significantly stronger and more dimensionally stable than solid sawn lumber of the same dimensions, allowing for even longer spans and custom shapes. * Rimboard: Rimboard, also known as rim joists or band joists, is used to cap the ends of I-joists and traditional joists, creating a continuous structural element around the perimeter of a floor or roof system. It is typically manufactured from structural composite lumber or engineered wood products, providing a strong and stable edge for the framing system. The materials used in onCENTER Blue Linx Engineered Products are primarily wood-based. Specific materials can include: * Wood Veneers: Thin layers of wood, often rotary cut, are a primary component in LVL. * Solid Sawn Lumber: Used for the flanges of I-joists and as individual strands in Glulam beams. * Oriented Strand Board (OSB) or Plywood: These engineered wood panels form the webs of I-joists. * Structural Adhesives: High-strength adhesives are crucial for bonding wood veneers in LVL and lumber strands in Glulam to create monolithic, durable products. The construction methods emphasize precision engineering, aiming to maximize material efficiency while achieving predictable structural performance. This results in products that are lighter, straighter, and stronger than traditional framing materials, offering advantages in installation and overall building integrity.Features and Benefits
