Final answer:
Laminated veneer lumber (LVL) and engineered wood I-joists are two engineered wood products that may replace conventional joists.
Step-by-step explanation:
Two engineered wood products that may replace conventional joists are laminated veneer lumber (LVL) and engineered wood I-joists.
Laminated veneer lumber (LVL) is made by bonding layers of wood veneers together to form a strong and stable product. It is commonly used for long-span applications, such as floor joists, beams, and headers.
Engineered wood I-joists consist of a plywood or oriented strand board (OSB) web with top and bottom flanges made of solid lumber or laminated veneer lumber. They provide excellent strength-to-weight ratio and are commonly used in residential construction.
