How to Choose the Right Plywood for Your Project: A Comprehensive Guide
Choosing the right plywood can be daunting, especially with the myriad of available options.
However, understanding the different types of plywood, their strengths, and their applications can make the process much easier.
This comprehensive guide will give you the knowledge to make an informed decision when selecting plywood for your next project.
Understanding Plywood
Plywood is a versatile and durable material made by glueing together thin layers of wood veneer, or 'plies'. Then, the grains of each layer are rotated, typically at right angles, to increase the strength and stability of the plywood.
Further, this construction method makes plywood resistant to warping, cracking, and twisting, making it a popular choice for many projects.
Types of Plywood
Several types of plywood are available, each with unique properties and applications.
Softwood Plywood
Softwood plywood is typically made from pine, fir, or spruce. It’s commonly used in construction and industrial applications due to its strength and affordability.
Hardwood Plywood
Hardwood plywood is made from deciduous trees such as oak, birch, and maple. It’s denser and more durable than softwood plywood, making it ideal for furniture and cabinetry.
Marine Plywood
Marine plywood is specially treated to resist moisture. And it’s used in applications where the plywood will be exposed to water, such as in boat construction.
Factors to Consider When Choosing Plywood
When choosing plywood for your project, there are several factors to consider.
Project Requirements
The type of project you are undertaking will largely determine the plywood you need. For example, if you are building outdoor furniture, you may need marine plywood to withstand the elements.
Quality
The quality of plywood can vary greatly. Higher-quality plywood will have more layers, providing greater strength and stability. It will also have fewer knots and imperfections, resulting in a smoother finish.
Cost
The cost of plywood can vary depending on the type and quality. While it may be tempting to opt for the cheapest option, it's important to consider the long-term durability and performance of the plywood.
Tips for Choosing the Right Plywood
Here are some tips to help you choose the right plywood for your project.
Check the Grade
Plywood is graded based on the quality of the faces. The highest quality is an 'A' grade, which is smooth and free from knots. 'B' grades may have minor imperfections, while 'C' and 'D' grades will have more knots and splits.
Consider the Thickness
The thickness of the plywood will affect its strength and stability. Thicker plywood is generally stronger but may also be heavier and more challenging.
Ask for Advice
If you're unsure about which plywood to choose, don't hesitate to ask for advice. At Woodshop Direct, our knowledgeable staff are always on hand to help you choose the right plywood.
Plywood for Specific Applications
In addition to the common types of plywood, speciality variants are designed for specific applications.
For instance, flexible plywood, aptly named for its flexibility, is perfect for projects requiring curves and rounded structures. Whereas fire-retardant plywood, treated to slow the spread of fire, can be essential in some construction projects.
For fine woodworking and cabinetry, veneered plywood with a layer of hardwood veneer on the surface can offer a premium look without the expense of solid hardwood.
Environmental Considerations
The environmental impact of your project is another crucial factor when selecting plywood.
Opt for plywood certified by the Forest Stewardship Council (FSC) or the Programme for the Endorsement of Forest Certification (PEFC) to ensure that the wood comes from responsibly managed forests.
Additionally, consider plywood with lower volatile organic compounds (VOCs) to reduce environmental pollution and health risks.
Reading Plywood Labels
Understanding the labels on plywood can provide valuable insights into its characteristics.
For example, labels often indicate whether the glue used is Exterior or Exposure 1.
Exterior means the plywood can withstand permanent exposure to weather elements, while Exposure 1 plywood can tolerate temporary exposure during construction.
Additionally, labels may also mention the moisture content. While most plywood has a moisture content of 10-20%, for certain applications like flooring, a lower moisture content may be desirable to minimise shrinkage.
Understanding Plywood Standards
Plywood is manufactured following certain standards, which dictate its quality and suitability for different applications.
European plywood standards (EN314 and EN636) and American Plywood Association (APA) are the most commonly used. These standards cover bonding quality, durability, and load-bearing capacity. So familiarise yourself with these standards to make an informed choice.
Plywood Size and Cut
While most plywood comes in standard 4x8 foot sheets, it's also available in other sizes.
Your project might require oversized sheets or smaller, precut panels. Also, remember to account for the saw kerf—the material removed by the saw blade—when planning cuts.
How to Store and Handle Plywood
Plywood's durability can be compromised if not stored and handled properly. It should be stored flat, away from direct sunlight and moisture. Also, use stickers (wooden strips) between layers of stacked plywood to allow air circulation and prevent warping.
Choosing the Right Tools for Plywood
Working with plywood requires the right tools. Carbide-tipped saw blades can provide clean cuts, reducing splintering. When drilling, use brad-point bits for precise holes. And if you paint or stain your plywood, sand it with a progression of grits, starting from a coarse 80-grit to a fine 220-grit for a smooth finish.
