Given its diverse applications, plywood can be adapted to meet the specific requirements of your project. To simplify the purchasing process, most suppliers and lumber stores categorize their plywood based on basic building material categories.

Types of Plywood: Structural vs. Interior

Structural Plywood

Structural plywood, also known as exterior plywood, is specifically designed for permanent use in building applications. It is primarily used in situations where strength and stability are of utmost importance. Key characteristics include:

- Thickness: Structural plywood is typically thicker and made from softwood species.

- Moisture Resistance: The majority of veneer core structural plywood exhibits moisture-resistant properties, safeguarding it against deformation.

- Durability: This type of plywood is primarily utilized in beams, subfloors, and bracing for walls or roofs.

Exterior Plywood

While exterior plywood is robust, it is engineered to withstand water exposure and harsh weather conditions. Important features include:

- Water-Resistant Adhesives: The adhesives in exterior plywood are specifically formulated to resist moisture and UV degradation, making them ideal for outdoor usage.

- Surface Treatments Required: For exterior installations, treatments like waterproof sealants are recommended to prolong its lifespan, especially when covered with siding, flooring, or roofing materials.

Interior Plywood

Contrary to its structural counterpart, interior (decorative) plywood is chosen primarily for its visual appeal rather than strength. Use cases include:

- Home Improvement Projects: Ideal for applications such as wall paneling, ceilings, and coffered ceilings.

- Furniture Construction: Frequently used in crafting cabinets and other furnishings.

It's essential to note that interior plywood is not suited for structural applications or outdoor environments. For those looking for a stunning appearance without the high cost of solid wood, hardwood plywood is a budget-friendly option that provides a beautiful real wood finish.

Plywood is an essential material in the construction and design industries due to its versatility, strength, and aesthetic appeal. Understanding the various types of plywood and their specific applications can help you make informed choices for your projects.
