Understanding Plywood Basics

Before diving into the specifics of kitchen-suitable plywood, let's briefly review what plywood is and how it's made.

What is Plywood?

Plywood is an engineered wood product made by gluing together thin layers (or "plies") of wood veneer. These layers are typically arranged with the grain of each layer running perpendicular to the adjacent layers, which gives plywood its strength and stability.

Plywood Grades

Plywood is categorized into different grades based on its quality and intended use. The grading system typically considers factors such as:

1. Face and back veneer quality
2. Core composition
3. Glue bond durability
4. Moisture resistance

Some common plywood grades include:

• A-A, A-B, B-B (for appearance-grade plywood)
• CDX, RTD (for construction-grade plywood)
• Marine Grade (for high moisture resistance)

Characteristics of Kitchen-Suitable Plywood

When selecting plywood for kitchen use, several key characteristics should be considered:

1. Moisture Resistance
2. Durability
3. Smoothness
4. Formaldehyde Emission
5. Fire Resistance
