Here are the key differences between LVL (Laminated Veneer Lumber), LVB (Laminated Veneer Board), and Normal Plywood:

1. Composition:
   • LVL (Laminated Veneer Lumber): Composed of thin veneer sheets that are bonded together with adhesives, usually in a parallel arrangement. Provides high strength and stiffness.
   • LVB (Laminated Veneer Board): Similar to LVL, it is made of thin veneer layers but may have a different arrangement or use a variety of core materials.
   • Normal Plywood: Constructed with layers of wood veneers glued together in a perpendicular arrangement. Comes in various grades and is suitable for a wide range of applications.
2. Strength and Stiffness:
   • LVL: Known for its exceptional strength and stiffness, making it suitable for structural applications, such as beams and joists.
   • LVB: Offers good strength and stiffness, similar to LVL, and may have variations based on specific construction and materials.
   • Normal Plywood: Provides strength suitable for various applications, but may not have the same structural capabilities as LVL.
3. Applications:
   • LVL: Commonly used in structural applications where high strength is required, such as in construction for beams and headers.
   • LVB: Used in a variety of applications, including furniture, cabinets, and general construction, depending on the specific type and construction.
   • Normal Plywood: Versatile and used in a wide range of applications, including furniture, cabinets, flooring, and general construction.
4. Cost:
   • LVL: Generally more expensive due to its high strength and specialized use in structural applications.
   • LVB: Cost may vary based on specific construction and materials, but it is often more affordable than LVL.
   • Normal Plywood: Typically more cost-effective compared to LVL, suitable for a variety of applications.
5. Appearance:
   • LVL and LVB: Can have a smooth and consistent appearance, making them suitable for visible surfaces in furniture and construction.
   • Normal Plywood: Comes in various grades with different surface appearances, allowing for options based on the desired aesthetic.

Understanding these differences can help in choosing the right material for specific project requirements.
