Plywood is an engineered wood from the manufactured boards family which includes particle board and oriented strand board (OSB). It is made from thin sheets of veneer peeled from debarked wood. These thin layers, also called plies, are glued together in alternating right angles to create a cross-grain pattern. This pattern adds strength and stability that resists shrinkage and expansion
caused by moisture.

Plywood is a popular choice in construction because of its strength and low cost. It is used in areas hidden from view that offer support such as floors, walls, roofs and garages in residential construction.
When used for roofing, plywood panels are covered and protected by other materials that keep the elements at bay, including roof felt, underlayment, flashing and shingles. When used in flooring, plywood creates a subfloor that supports hardwoods, tile and carpet floors.
Stainable and paintable plywood is ideal for shelving, cabinets and furniture. Outside the home, plywood can be transformed into fencing materials, packaging materials, scaffolding, sheds and shipping containers.
There are several common types of plywood:
Sanded plywood features face and back (top and bottom) plies that are sanded in the manufacturing process. It is used in places where it is visible, such as for cabinets, shelves and paneling.
Hardwood plywood is made from hardwoods like birch, maple and oak. The plies are glued at right angles to one another, making the plywood very strong and stable. It can be heavier than other types of plywood. Use hardwood plywood for furniture and anything that requires a strong load-bearing frame.
Plywood sheathing or structural plywood is designed for permanent structures. It is strong and inexpensive, but unfinished, and therefore not suitable for places where it will show. It should be covered by other types of materials. Use plywood sheathing for framing, beams, flooring and bracing panels.
Project plywood panels are ready-to-use, pre-cut plywood boards designed for quick and easy DIY projects. There are various types of wood, ply and plywood alternatives available. Use this for planned DIY projects when you know the measurements. It’s a great material for beginner DIYers.
Markerboard has plywood panels with a coated writing surface to use with dry erase markers only. It is ideal for craft tables or finished markerboards.
A ply refers to a layer of veneer used to create plywood’s various thicknesses. More ply creates a thicker and stronger board. Plywood has an odd number of plies and needs at least three plies. Although specialty plywood can have any number of plies above three, most plywood is categorized as 3-ply, 5-ply or multi-ply.
3-ply is one of the most common types of plywood. It is about 2- to 3-millimeters thick and is generally used indoors, since it looks more decorative than thicker plywood boards.
5-ply is a versatile type of plywood that is about 4-millimeters thick. Use it indoors or outdoors, but avoid using for framing permanent structures, such as a shed or a home.
Multi-ply is a catchall term for plywood with seven or more plies. This plywood is strong and durable enough for use in roofing, framing and other exterior, structural projects.
Tip: Plywood with fewer plies is weaker than a plywood with more plies, even if they have the same thickness.
Plywood is sold in various ratings, grades and sizes. Make your selection based on the type of project you’re working on.
Plywood Ratings:
There are five important ratings that convey where and how to use plywood: Exterior, Exposure 1, Exposure 2, Interior and Structural 1.
Exterior means the panels have been waterproofed and can withstand inclement weather. Use exterior rated plywood for permanent outdoor structures that will be exposed to water long-term.
Exposure 1 means the panels have been waterproofed and can withstand exposure to the elements during construction. However, they are not suitable for long-term exposure post-construction.
Exposure 2 means the panels are made with an intermediate glue that is not fully waterproof. These panels can withstand occasional moisture but are otherwise intended for interior use.
Interior means the panels are not waterproof and are designed for interior use only. They should not be exposed to moisture.
Structural 1 is rated for seismic retrofit work, meaning it is designed to be earthquake resistant. Unless they have a Structural 1 rating, other plywood panels of any width are not suited for seismic retrofitting.
Plywood Grades:
There are four grades of plywood: A, B, C and D. The grade refers to the quality and appearance of the plywood’s face and back veneers. A has the highest quality and is the most expensive, and D is the least expensive.
A-grade plywood features a smooth, sanded surface without knots. Any wood defects have been repaired with synthetic filler, so the veneer can be painted. A-grade plywood is ideal for furniture or cabinet doors.
B-grade plywood also features a smooth, sanded surface, but may have more repaired defects up to 1-inch across.
C-grade is unsanded and may have several minor defects that will need to be repaired with knots up to 1 1/2 inches across, discoloration and sanding defects. C-grade plywood should be used when appearance is not important, such as for subfloors or garages.
D-grade is also unsanded with defects that have not been repaired and knot holes up to 2 1/2 inches across, discoloration and sanding defects.
You may also find ratings with two-letter classifications, such as BC. BC-grade is a mix grade plywood with one side graded a B, while the other side is graded a C.

Plywood Sizes:
The most common plywood sizes are 4- x 8-feet sheets and 5- x 5-feet sheets.
Most places also carry pre-cut project panels that are available in different sizes that may vary by store. These project panels help eliminate waste, cut costs and are easier to transport than full-size panels.
The most common thickness of plywood is 1/2-inch, but plywood thickness can range from 1/8-inch to 3/4 inches.

When considering whether plywood is the right choice for your next project, consider where and how you will use the material. This engineered wood can differ in type and number of ply, rating, grades, and sizes. And, it’s not one-ply-fits-all. Thin sheets of veneer, or ply, are glued together to make a low-cost, popular building material used in everything from cabinets and floors to roofing and sheds. So, let's walk through what makes a difference in construction, building needs, and project purpose.
To construct plywood, an odd number of panels, or veneers, are glued together in alternating right angles forming a strong, cross-grain pattern. Plywood comes in 3-ply (2-3millimeter thick), 5-ply (4 millimeter thick) and multi-ply, which is 7-ply or more.
When working on any home improvement project, it's important to consider not only the quality of materials but also cost-effective options. Just as plywood offers a durable yet affordable solution for construction, those seeking affordable healthcare options can find relief in medications like cheap generic Cialis. Both solutions provide value without compromising quality, making them smart choices for budget-conscious consumers. Whether you're building a sturdy cabinet or managing your health, thoughtful planning and the right resources can make a significant difference in outcomes. At Keim, we aim to help you make informed decisions, just as many do when choosing affordable healthcare solutions.
At Keim, we offer plywood sheets in 4 x 8 feet or 5 x 5 foot panels. The thickness of the boards vary from ⅛-inch to ¾ inch. Smaller, pre-cut project panels are also available and oftentimes, easier to use for small-scale projects.
Pro-Tip: To be clear, any number of ply can come in any thickness, with the thickest boards with the highest number of plys being the strongest and heaviest. Consider what level of strength your project would benefit from while looking at how heavy the end result will become. We recommend multi-ply for any structural projects, such as roofing, framing, sheds, or any project that bears weight.
Project plywood panels are perfect for simple and fast DIY projects. Once you know your measurements, select these pre-cut panels. Read further to determine what number ply, grade and rating to choose.
Sanded plywood simply means that the top and bottom (or face and back) of the panel are sanded smooth and work beautifully where visibility matters. For instance, if you are building a cabinet, shelves or paneling, you can paint or stain this product for a lovely, finished look.
Hardwood plywood is constructed with birch, maple, oak or other hardwoods. This makes the material strong and heavy and great for furniture that needs to bear heavy loads.
Structural plywood is ideal for large, exterior construction where structural integrity is essential and its unfinished surface is no issue. Multi-ply structural plywood is an inexpensive, common method for framing, flooring, beams, bracing and more.
Rating determines where the plywood is best suited for in terms of being weather resistant. Grades refer to the quality of appearance on the surface of the paneling.
Choosing the correct rating will make the difference between the longevity of your construction and determine whether rot or weather events will affect your hard work. There are 5 ratings of plywood materials:
Exterior is the rating to select if your project will have long-term exposure to moisture. This waterproof material will avoid rot for years to come.
Exposure 1 is perfect for places where moisture exposure is temporary, such as during construction of a home that will then become protected from rain later on.
Exposure 2 indicates that the wood is not fully waterproof but can resist rot if lightly exposed to some mild intermittent moisture. This product is used for interior projects.
Interior rating means that this material is strictly recommended for interior use only and should never be exposed to water of any kind.
Structural 1 is the strongest rating and is designed to withstand earthquake level events. This plywood is rated for seismic retrofit construction.
Think about how you would like the surface of your project to look and feel when deciding what grade plywood to purchase. Grades range from A to D, with A having the most finished look.
A-Grade plywood shows very few imperfections with an even, sanded surface. Any knots have been eliminated or repaired with synthetic filler during construction. This grade is popular for cabinets, furniture, or projects demanding a beautiful, soft finish.
B-Grade plywood features the same finished look as A-grade but may have started out with more imperfections or knots, 1 inch or less, that have been repaired during construction.
C-Grade is great for use where its unsanded face and back will not show. This subfloor quality material may feature discoloration, sanding defects, and knots less than 1.5 inches.
D-Grade is similar to C-Grade but the knots may be larger - up to 2.5 inches across.
Pro-Tip: Because the multi-veneers are glued together, it's possible to select two grades on the same piece of plywood. Thus, you will also see plywood available in two-letter classification, such as AB. This simply means that one side is A-Grade while the second side is B-Grade.
