Laminated plywood

Types of Laminated Plywood

Laminated plywood is a type of engineered wood product made by bonding layers of thin veneer sheets with resin. It combines the strength and stability of plywood with the added benefits of being laminated, such as improved surface durability, moisture resistance, and aesthetic versatility. Laminated plywood is widely used in construction, furniture manufacturing, and interior design due to its strength, stability, and versatile applications.

There are different types of laminated plywood based on construction, coatings, and applications:

• Based on Construction:

  Laminated Veneer Lumber (LVL): LVL is a type of engineered wood product made from multiple layers of thin wood veneers bonded together with adhesive. It is similar to plywood but with a specific focus on providing high strength and stability. LVL is used in applications where load-bearing capacity is crucial, such as beams, headers, and joists. It can be produced in long lengths and consistent cross-sections, making it a preferred choice for structural components in residential and commercial construction. LVL is often used in areas where traditional solid wood would be prone to warping, shrinking, or cracking under load or due to moisture.

  Plywood: Laminated plywood is created by gluing together several layers of thin wood veneers with an odd number of layers. The grain of each layer is oriented at right angles to the layer before it. This cross-laminated design gives it exceptional strength and stability. It is a versatile building material used in everything from subfloors, and roof decking to furniture-grade panels. It comes in various grades and thicknesses, making it suitable for both structural and aesthetic applications.

• Based on Coating:

  Melamine Coated Plywood: Melamine coated plywood is laminated plywood with a melamine resin layer applied to one or both sides. This resin layer is typically infused with decorative patterns or colors. This type of laminated plywood is known for its smooth, hard, and scratch-resistant surface. It is often used in furniture, cabinetry, and countertops where a durable and aesthetically pleasing finish is required.

  Film-Faced Plywood: Film-faced laminated plywood is treated with a durable plastic film resin overlay. This film is often phenolic resin-based, providing a waterproof and wear-resistant surface. This type of laminated plywood is commonly used in formwork for concrete structures, temporary flooring in high-traffic areas, and other applications requiring a tough, easy-to-clean surface. It is available in a range of thicknesses and grades to suit different load-bearing and aesthetic requirements.

• Based on Applications:

  Decorative Plywood: This laminated plywood is engineered specifically to provide an attractive appearance. It features decorative veneers, such as walnut, oak, or maple, laminated onto a plywood core. This type of laminated plywood is used in fine furniture, cabinetry, interior doors, and wall paneling. It is chosen for its aesthetic appeal rather than structural strength.

  Structural Plywood: Structural laminated plywood is designed primarily for strength and load-bearing capacity. It is constructed with a solid core and multiple layers of cross-banded veneers. This type of laminated plywood is graded for strength and stability. It is used in applications such as subflooring, roof sheathing, and load-bearing walls. Structural laminated plywood is ideal for applications requiring high strength, durability, and resistance to warping and bending.
