Using plywood in cabinet construction has several advantages, and the characteristic of not expanding or contracting with moisture is significant. Plywood is composed of multiple layers of veneer glued together with the grain of each layer oriented in different directions. This construction method gives plywood a level of dimensional stability that is superior to that of solid wood.

Solid wood tends to absorb moisture from the environment, causing it to expand in high humidity and contract when it dries out. This can lead to warping, cracking, and structural issues in cabinetry over time. Plywood's layered design helps to counteract these effects, making it a more reliable choice for cabinetry that may encounter fluctuations in humidity and temperature.

Understanding this property of plywood is essential for cabinetmakers, as it allows them to create durable and long-lasting pieces that maintain their shape and performance through varying environmental conditions. This stability makes plywood a favored material in both residential and commercial cabinetry projects.
