Final answer:
Engineered wood products such as plywood, laminated veneer lumber, parallel strand lumber, and Parallam are examples used in construction that result from an efficient lumber industry process of turning logs into stackable and transportable materials, utilizing even the waste for additional products.
Step-by-step explanation:
In the lumber industry, efficiency is key in transporting and processing logs from the forests to the market. Logs are first taken to sawmills close to the forests to be processed into lumber because it is more efficient and cost-effective. This lumber can be easily stacked and transported. During this process, waste material such as sawdust and wood chips are used to create engineered wood products that are also easy to transport. Some examples of engineered wood products used in construction include:
- Plywood: Layers of wood veneers are bonded together to form flat sheets, widely used in construction for flooring, walls, and roofs.
- Laminated veneer lumber (LVL): Made by bonding layers of wood veneers with adhesives, LVL has high strength and is used for beams and other structural components.
- Parallel strand lumber (PSL): Consists of long strands of wood bonded together, PSL is used in load-bearing applications such as beams and columns.
- Stamina wood or Parallam: A specific type of PSL, known for its high strength and used in posts, beams, and other structural elements.
