Plywood is a staple material for professional builders, architects, designers and DIYers alike. These versatile panels are used for a number of different projects, from wall sheathing, roofing, and sub-flooring, to cabinetry and furniture. Plywood is readily available at local retail stores and specialty wholesalers, with most offering a wide selection.
Gaining better knowledge of plywood and the types of plywood available will not only make shopping easier, but it will also ensure that your finished project will have stability, structure, and beauty.
There are two main types of plywood: softwood plywood and hardwood plywood.
They are both are made of multiple plies (layers) of thin wood veneer that have are glued under pressure within a chamber set to a high temperature to ensure maximum adhesion and strength.
Softwood plywood comes in different wood species, but fir and pine are most common. Softwood plywood is ideal for projects where cost must be kept down or where the look of the plywood is not a priority, such as with wall sheathing or subflooring. Hardwood plywood is more expensive but is considered more visually appealing.
Hardwood plywood can differ from softwood in how the panels are constructed. Hardwood panels may have multi-ply layered construction, like softwood plywood, but often, you&#;ll find that they&#;re instead constructed with one-piece composite wood cores.
The plywood face and back then feature a thin decorative hardwood veneer which can be stained, sealed or painted, depending on the preferences of the customer.
Hardwood plywood is intended for interior, non-structural applications like for furniture, cabinetry, finished interior walls and similar projects. Typical hardwood plywood face species include oak, walnut, maple, hickory and many more.
Plywood has many uses, so you can really use whichever type you deem fit based on the project you&#;re building. However, to make shopping for plywood easier, most suppliers or lumber stores will break down their plywood in basic categories.
Structural or exterior plywood, like CDX plywood, is designed for permanent use in building structures like beams, subfloors, bracing for walls or roofs, and in any other instance where strength and stability are vital. Structural plywood is often quite thick, made of softwood species and without an attractive finish. The majority of structural plywood is moisture-resistant.
Exterior plywood is going to be fairly strong, but most importantly, it&#;s designed for water-resistance and weather exposure. Adhesives used in Exterior plywood withstand water and harsh sunlight for longer without degradation. However, Exterior plywood that will be directly exposed to the elements will still need a surface treatment (e.g. waterproof sealant) as it is designed to be covered with siding, flooring, roofing, etc.
Interior (decorative) plywood is usually chosen for its looks rather than its strength. You&#;ll find Interior plywood ideal for household projects like wall paneling, ceilings, and ceiling treatments (e.g. coffered ceilings) cabinets and furniture. Interior plywood should not be used for structures nor should it be used outdoors.
If you&#;re looking for exceptionally beautiful look, consider skipping softwoods and selecting an interior, hardwood product instead. Hardwood plywood is a budget-friendly way of getting a stunning real wood finish without the price tag of solid wood.

As mentioned above, hardwood plywood comes in a variety of different cores. The core materials offered by Columbia Forest Products include:
The core you choose depends on a few factors. If budget is a concern and weight is not a factor, typically particleboard or MDF is chosen. MDF is a great alternative to particleboard if you need a very smooth finish, but it&#;s important to know it&#;s heavier.
If a very high-quality finish is needed or you want to eliminate the need to finish edges, then Europly Plus is a solid choice. Lastly, if a light weight, sturdy, moisture-resistant material is desired, a PureBond veneer core material makes a great choice.
Columbia Forest Products offers a variety of face veneers to compliment their cores. You can find essentially any North American hardwood species available as a veneer. Visit the Columbia Forest Products website for examples of veneer options.
Grade refers to the relative visual quality of the plywood&#;s face and back. The face of the plywood is often graded by letter while the back is graded by number. The higher the grade, the higher the price of the plywood.
For a plywood face, you&#;ll find a grade range of &#;AA&#; to &#;E&#;. Plywood faces with an &#;AA&#; grade are exceptionally high quality and ideal for custom cabinetry, furniture or similar projects. An &#;A&#; grade is just a step below and is a common grade for the higher-end plywood options. &#;B&#; grade plywood is often referred to as &#;cabinet grade.&#; Grade &#;C&#; is still useful for finished work, like the interior of cabinets or shelves. Many people use &#;D&#; or &#;E&#; grades for areas that won&#;t be seen, or that will be painted.
For the plywood back, you&#;ll find a range of 1 to 4, which are generally matched to the relative quality of the face. The grade of the plywood might be indicated on panel edges. Grades are typically expressed with the face grade first, followed by the back grade, such as &#;A-1&#; or &#;C-3&#;.
By understanding the various types of plywoods and how they&#;re graded, you&#;ll be able to more accurately purchase panels that will be best suited for the project at hand.

Over the years, plywood has become the building material of choice for professional woodworkers, carpenters and amateur DIY-ers alike. From its sustainability to its extreme versatility, plywood is the perfect material for many projects.
Plywood is made from timber cut into sheets and pressed together under pressure using adhesive. Impressively solid and versatile, the cross-lamination of panels in birch plywood allow it distributes the force over a wider surface area, causing it to be highly resistant to impact. Despite its strength, plywood maintains impressive levels of flexibility, making it perfect for use in furniture or anything that uses curved surfaces.
Due to the application of substances to wood veneers during the manufacture of the plies that make up plywood, it is moisture-resistant and chemical-resistant. This resistance makes plywood a better choice than MDF for use in general-purpose home furniture such as tables, chairs, decking and planters, as it is in industries in which exposure to chemicals is commonplace.
As well as being an excellent thermal and noise insulator, plywood carries an aesthetic appeal. The warm and natural aesthetic of birch plywood is both timeless and contemporary, making it easy on the eye in most uses.
Boasting all of these benefits and their affordability, it is hardly surprising that individuals and businesses of all sizes reap the benefits of birch plywood as a material.
