Plywood: What You Need to Know

Plywood, also known as engineered wood or layered wood panels, is a durable and versatile material crafted by bonding thin wood veneers together for strength and stability. Available in exterior and interior types, it suits a wide range of applications. Exterior plywood features water-resistant adhesives and treatments, making it ideal for siding, roofing, and other outdoor projects. Interior plywood, on the other hand, offers smooth surfaces and high aesthetic value, perfect for furniture, cabinetry, and wall paneling in controlled environments.

Grades:

  • A Grade: A-grade plywood has a smooth, sanded surface with minimal knots, making it ideal for high-visibility applications like cabinetry and paneling. It offers the highest surface quality.
  • B Grade: Slightly less refined than A-grade, B-grade plywood contains minor imperfections but maintains a polished appearance suitable for applications where aesthetics matter.
  • C Grade (C2, C3, C4): C-grade plywood is designed for structural uses like bracing and subfloors. The numbers (2, 3, 4) indicate increasing imperfections, with higher numbers having more flaws while preserving structural strength.
  • D Grade: D-grade plywood has the roughest surface, with visible knots and defects. It is commonly used for structural purposes where appearance is not a priority.

Examples:

  • AC Grades: These grades feature an A-grade face and a C-grade back, providing a smooth, refined surface on one side for visible applications like cabinetry or interior paneling. AC is an excellent choice for interior projects requiring both aesthetic appeal and structural reliability.
  • CDX Plywood: CDX plywood is an exterior-grade material combining a C-grade face and D-grade back. It is cost-effective and moisture-resistant, making it a dependable choice for roofing and sheathing.

Features:

  • Pressure-Treated: Pressure-treated plywood is infused with chemicals to enhance its resistance to moisture, decay, and insects, making it ideal for outdoor and ground-contact applications.
  • Fire-Retardant Treated: Fire-retardant plywood is specially treated to slow flame spread and reduce smoke production, meeting industry standards such as ASTM E84 and NFPA 703.
  • Sanded: Sanded plywood offers a smooth, polished surface perfect for projects requiring a clean finish, such as cabinetry, shelving, or decorative wall panels.
  • Prefinished: Prefinished plywood comes with a factory-applied finish, eliminating the need for on-site painting or staining, providing a professional appearance.
  • Sheathing: Sheathing-grade plywood provides structural stability for walls, roofs, and subfloors in both residential and commercial buildings.
  • T&G (Tongue and Groove): T&G plywood features interlocking edges that create a snug fit, ensuring stability and reducing gaps in flooring or decking applications.

Materials:

  • Hardwood: Hardwood plywood is prized for its strength and durability, made from species like oak, maple, or birch. It provides a premium look while maintaining excellent load-bearing capabilities for structural applications.
  • Softwood: Softwood plywood, typically made from pine or fir, is lightweight and cost-effective, making it suitable for general construction, roofing, and subflooring.

Plywood FAQ

Can I schedule plywood deliveries to specific neighborhoods like Pasadena or Manhattan Beach?

Yes. Supply Ontime offers same‑day or scheduled deliveries of plywood panels throughout Greater Los Angeles. When ordering, provide the job‑site address and any special instructions. For tight streets in areas like Silver Lake or downtown, scheduling a two‑hour window helps ensure we arrive when access is available.

 When should I choose plywood instead of OSB?

Plywood resists moisture better than OSB and will dry out and return to its original thickness after getting wet. OSB takes longer to absorb water, but once saturated, it swells more and remains swollen. Plywood is also stiffer, and nails or screws are more likely to stay secure. If you’re building in a damp microclimate or expect frequent rain, use exterior‑grade or marine plywood.

How should I store plywood panels to prevent warping?

Store plywood in a dry location with good ventilation that protects it from sunlight and moisture exposure. The presence of moisture leads to warping and delamination of the material. Stack the sheets flat on a level surface that provides enough support for even weight distribution while keeping them elevated from the ground, and use a breathable tarp or plastic sheet for protection against dust and moisture while maintaining airflow. These protective measures function to stop harm from occurring in the humid climate of coastal Los Angeles.

What is the difference between hardwood and softwood plywood?

Hardwood plywood is made from dense woods like oak, birch, or maple, giving it greater strength and a smoother surface that is ideal for furniture, cabinetry, and visible finishes. Softwood plywood, made from pine, fir, or spruce, is lighter and often used for structural applications like roofing, subflooring, and wall sheathing. In Los Angeles construction, hardwood plywood is often chosen for high-end interior projects, while softwood plywood is preferred for framing and large-scale builds where durability and cost efficiency are priorities.
