1. Type
Understanding the distinction between softwood, hardwood, and marine-grade plywood is paramount in the context of “how to buy plywood.” The type of plywood directly influences its properties and suitability for specific applications.
Softwood plywood, derived from coniferous trees such as pine and fir, is characterized by its lightweight and cost-effectiveness. Its moderate strength and stiffness make it suitable for general construction purposes, including framing, sheathing, and subflooring.
Hardwood plywood, crafted from deciduous trees like oak, maple, and birch, offers superior strength, durability, and dimensional stability compared to softwood plywood. Its resistance to wear and tear makes it ideal for high-traffic areas, furniture making, and cabinetry.
Marine-grade plywood is specially engineered to withstand harsh marine environments. It is manufactured using waterproof adhesives and durable face veneers, making it resistant to moisture, rot, and insects. Marine-grade plywood is commonly employed in boatbuilding, dock construction, and other applications where exposure to water is a concern.
Choosing the appropriate type of plywood is crucial to ensure the successful execution of your project. By considering the specific requirements of your application, you can select the plywood that best aligns with your needs, maximizing performance and longevity.
2. Thickness
The thickness of plywood, ranging from 1/8 inch to 1 inch or more, is a critical factor to consider when purchasing plywood. It directly influences the strength, rigidity, and suitability of the plywood for various applications.
-
Structural applications
For structural applications such as framing and subflooring, thicker plywood is preferred. It provides greater strength and rigidity, ensuring the structural integrity of the building. Common thicknesses for these applications include 1/2 inch, 5/8 inch, and 3/4 inch.
-
Non-structural applications
For non-structural applications such as paneling and cabinetry, thinner plywood may be sufficient. It is lighter and more flexible, making it easier to work with and shape. Common thicknesses for these applications include 1/4 inch, 3/8 inch, and 1/2 inch.

Special applications
In certain specialized applications, such as boatbuilding or outdoor structures, thicker plywood may be required to withstand higher loads or exposure to harsh elements. Plywood with a thickness of 1 inch or more is often used in these scenarios.
-
Cost considerations
It is important to note that thicker plywood is generally more expensive than thinner plywood. Therefore, it is essential to select the appropriate thickness based on the specific requirements of the application, balancing cost with performance.
By understanding the relationship between thickness and the intended use of plywood, you can make informed decisions when selecting the right plywood for your project, ensuring optimal performance and cost-effectiveness.
3. Grade
Understanding the grading system of plywood is integral to “how to buy plywood” as it directly affects the quality, appearance, and cost of the plywood. The grade of plywood is determined by the quality of the face veneer, which is the outermost layer of plywood. Higher grades indicate a smoother, more blemish-free surface, while lower grades may have imperfections or knots.
A-grade plywood is the highest grade, featuring a smooth, uniform surface with minimal defects. It is commonly used for high-end furniture, cabinetry, and other applications where appearance is critical. B-grade plywood has a slightly rougher surface with some minor imperfections, making it suitable for projects where aesthetics are less important, such as subflooring or sheathing. C-grade plywood has a more rustic appearance with more noticeable imperfections and knots. It is often used for industrial applications or as a base for other materials.
Knowing the different grades of plywood allows you to select the most appropriate material for your specific project. By considering the desired appearance, durability, and cost requirements, you can make an informed decision that optimizes the performance and value of your plywood purchase.
4. Finish
The finish of plywood, whether sanded, unsanded, or coated, is a crucial consideration when purchasing plywood. This seemingly minor detail significantly impacts the plywood’s appearance, functionality, and overall suitability for various applications.
Sanded plywood has a smooth, uniform surface that is ideal for painting, staining, or applying a clear finish. It is commonly used for interior applications such as furniture making, cabinetry, and wall paneling, where a refined finish is desired. Unsanded plywood, on the other hand, has a rougher surface with visible wood grain and imperfections. It is often used for exterior applications such as sheathing, subflooring, and crate construction, where a smooth finish is less critical.
Coated plywood has a protective layer applied to its surface, making it resistant to moisture, UV rays, and other environmental factors. It is commonly used for exterior applications, such as siding, roofing, and outdoor furniture, where durability and weather resistance are essential.
Understanding the different finishes available for plywood allows you to select the most appropriate material for your specific project. By considering the desired appearance, durability, and cost requirements, you can make an informed decision that optimizes the performance and value of your plywood purchase.
5. Moisture Resistance
Understanding the moisture resistance properties of plywood is crucial in the context of “how to buy plywood” as it directly influences the suitability of plywood for various applications and environments. Plywood is categorized into two main types based on moisture resistance: interior and exterior.
-
Interior plywood
Interior plywood is designed for indoor use and is not suitable for prolonged exposure to moisture or outdoor conditions. It is commonly used for applications such as furniture making, cabinetry, and wall paneling, where moisture resistance is not a primary concern.
-
Exterior plywood
Exterior plywood, on the other hand, is manufactured with water-resistant adhesives and coatings, making it suitable for outdoor use and exposure to moisture. It is commonly used for applications such as siding, roofing, and outdoor structures, where durability and weather resistance are essential.
Choosing the appropriate moisture resistance grade of plywood is crucial to ensure the longevity and performance of your project. By considering the intended use and exposure conditions, you can select the most suitable plywood that meets your specific requirements.
