Combi Plywood: The Ultimate Guide to Understanding Its Uses and Benefits

by admin | 05. 02, 2024

Combi plywood, also known as combination plywood, is a type of engineered wood that is made by combining two or more different species of wood. This type of plywood is becoming increasingly popular due to its versatility and strength. Combi plywood is made by layering thin sheets of wood veneer on top of each other, with each layer placed at a right angle to the previous one. This cross-grain construction makes the plywood stronger and more durable than traditional plywood.

One of the main benefits of combi plywood is that it combines the best features of different types of wood. For example, one layer of the plywood might be made from a hardwood like birch, while another layer might be made from a softwood like pine. By combining these two types of wood, the resulting plywood has the strength and durability of hardwood, as well as the affordability and flexibility of softwood. Additionally, combi plywood is available in a range of thicknesses and sizes, making it suitable for a wide variety of applications.

Material Composition

Combi plywood, also known as combination core plywood, is a type of composite plywood that is made by combining two or more wood species. The core of combi plywood is typically made of an inner core of wood plies and an outer layer of MDF or particleboard. The face and backing veneer are then added to the MDF or particleboard layer.

The wood species used in the core of combi plywood can vary depending on the manufacturer. Some common wood species used include birch, pine, Eucalypt, poplar, and different red hardwood species. The use of multiple wood species in the core of combi plywood allows for a combination of their unique properties, resulting in a product that is stronger and more durable than plywood made of a single wood species.

Manufacturing Process

The manufacturing process of combi plywood involves gluing together thin slices of wood, also known as veneers, and MDF or particleboard under high pressure and temperature. The number of layers of combi core plywood can vary from 5 to 13, depending on the thickness and intended use of the plywood.

Combi plywood is available in a variety of thicknesses, ranging from 1/4″ to 1-1/4″. The most common thicknesses for combi plywood are 1/2″, 5/8″, 3/4″, and 1″. Combi plywood is also available in a range of sizes, with 4′ x 8′ being the most common size.

Overall, combi plywood is a versatile and durable product that is suitable for a wide range of applications. Its unique composition and manufacturing process make it a popular choice for furniture, cabinetry, and other woodworking projects.
