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.
