Manufactured Board Properties

Manufactured Board Properties

Manufactured Boards, also known as Engineered Wood or Composite Boards, have revolutionized the world of woodworking since the 1950s. These sheet materials are created by pressing and bonding together wood particles, fibers, or veneers, resulting in greater stability, predictability, and cost-effectiveness compared to solid timber.

One of the key advantages of Manufactured Boards is their versatility in terms of applications. They can be easily worked with common woodworking tools, although power tools and machinery are often used for shaping and forming. This has enabled the growth of flat-pack furniture, making it more accessible and convenient for consumers.

There are various types of Manufactured Boards available, each with its own unique properties and applications. Plywood is made by bonding hardwood veneers together, offering strength and durability. Fiberboards are created by compressing wood fibers, ideal for interior applications. Particle boards, made from wood particles and resin, are commonly used in furniture and construction. And finally, blockboards are constructed from strips of wood sandwiched between veneers, providing stability and strength.

Understanding the properties of Manufactured Boards is essential for finding the right material for your project. In the following sections, we will delve into the specific characteristics and uses of Plywood, Medium Density Fibreboard (MDF), and Particle Board.

Key Takeaways:

  • Manufactured Boards offer greater stability, predictability, and cost-effectiveness compared to solid timber.
  • Various types of Manufactured Boards are available, including Plywood, Fiberboards, Particle Boards, and Blockboards.
  • Plywood is known for its strength and durability.
  • MDF is a composite panel product with a smooth surface, perfect for a wide range of applications.
  • Particle Boards are commonly used in furniture and construction.

Plywood Properties

Plywood is a versatile type of manufactured board that offers a range of properties suitable for various applications. With its distinct advantages, plywood has become a popular choice in construction, woodworking, and furniture making. Let’s explore some of the key properties of plywood and its different variations.

Plywood Grades and Applications:

GradePropertiesApplications
Exterior PlywoodDurable, weather-resistant, can withstand moisture and humidityOutdoor furniture, external cladding, roofing
Interior PlywoodSmooth surface, suitable for painting and finishingIndoor furniture, cabinetry, paneling
Marine PlywoodHighly resistant to water and moisture, very durableBoat building, docks, marine applications
Birch PlywoodStrong, stable, lightweight, easily bendableFine furniture, cabinet making, curved designs
Ply SheathingStructurally sound, provides stability and supportFlooring, roofing, temporary screening

Plywood’s properties vary based on its grade and intended use. Exterior plywood is engineered to withstand harsh weather conditions and is commonly used in outdoor applications such as furniture and cladding. Interior plywood, on the other hand, is designed for indoor use and provides a smooth surface that can be painted or finished to suit various décor styles. Marine plywood, as the name suggests, is specifically designed to withstand exposure to water and moisture, making it ideal for boat building and marine applications.

Birch plywood is known for its strength, stability, and lightweight properties. It can be easily bent to create curved forms, making it popular in furniture and cabinet making industries. Ply sheathing, on the other hand, is a structural plywood that provides stability and support, making it suitable for flooring, roofing, and temporary screening installations.

In summary, plywood is a highly versatile manufactured board with distinct properties. Its wide range of grades and applications make it a practical choice for various projects in construction and woodworking. Whether you need weather-resistant protection or a smooth and stable surface, there is a plywood variation to suit your needs.

MDF and Particle Board Properties

Medium Density Fibreboard (MDF) is a versatile composite panel product. It is made by combining wood fibres with a synthetic resin under heat and pressure. The result is a hard, flat, and smooth surface that lends itself to a wide range of applications. MDF is commonly used for doors, mouldings, skirting boards, internal panelling, and shelving. It provides a cost-effective alternative to solid wood, while maintaining excellent stability and uniformity.

One of the advantages of MDF is its consistency and predictability. It is free from defects such as knots or grain variations, making it easier to work with and ensuring a smooth finish. MDF also has excellent screw holding capacity, providing a reliable base for fixings. Additionally, the absence of natural wood properties, such as knots, makes MDF a more uniform material that can be painted or finished without the risk of blemishes.

Particle board, another type of manufactured board, is made by compressing wood particles with resin. It offers similar advantages to MDF, including affordability and ease of use. Particle board is commonly used for furniture, cabinets, countertops, and shelving. It provides a stable and cost-effective option, especially when covered with laminate or veneer for a more polished appearance. However, it is important to note that particle board is not suitable for applications where moisture resistance is required, as it can swell or lose structural integrity when exposed to water.

Both MDF and particle board have their own unique set of properties that make them suitable for different applications. MDF excels in areas where a smooth and consistent finish is required, whereas particle board is often chosen for its affordability and versatility. Understanding the properties of these manufactured boards can help guide you in selecting the right material for your specific project.
