Construction and Materials
Boise Cascade offers a range of engineered wood products designed for structural applications. One prominent category includes Laminated Veneer Lumber (LVL), a versatile and engineered wood product.
Construction and Materials
LVL is manufactured by bonding together multiple layers of thin wood veneers. These veneers are carefully selected and dried, then coated with a durable adhesive. The layers are oriented in the same direction, parallel to the length of the product. This structural composition provides superior strength and stability compared to traditional solid lumber of the same dimensions.
- Materials: High-quality wood veneers, durable structural adhesives.
- Manufacturing Process: Veneers are dried, coated with adhesive, and then consolidated under heat and pressure to form a solid, uniform product.
- Orientation: All wood grain is oriented parallel to the length of the LVL.
Product Characteristics
The engineered nature of LVL offers several advantages for construction:
- Strength and Stability: LVL possesses uniform strength characteristics and is highly resistant to warping, twisting, and shrinking.
- Load-Bearing Capacity: Its consistent properties allow for predictable and reliable load-bearing capabilities, making it suitable for demanding structural applications.
- Dimensional Consistency: LVL is manufactured to precise dimensions, ensuring a consistent fit during construction.
- Versatility: It can be used in a variety of applications, including beams, headers, rim board, and flange material for wood I-Joists.
