Question: 1 / 400

Which material is less prone to warping due to humidity changes?

Solid wood

Particleboard

Plywood

Plywood is less prone to warping due to humidity changes because of its construction. It is made by gluing together several thin layers of wood veneer, with each layer's grain oriented in alternating directions. This cross-lamination technique helps distribute the stresses that occur from changes in moisture content, making plywood more dimensionally stable than solid wood. Solid wood has a tendency to warp, twist, or cup as it absorbs or loses moisture, which can lead to issues in cabinetry and furniture assembly.

In addition, while particleboard and MDF (medium-density fiberboard) are engineered wood products that also provide some degree of resistance to moisture-related changes, they have limitations. For instance, they can swell or break down more easily when exposed to excessive moisture compared to plywood. Therefore, plywood's unique structure provides it with superior stability, making it the best choice in this context.
