Cross-ply core
The layered substructure of engineered flooring, with each layer oriented at 90° to the one beside it.
Cross-ply construction is what makes engineered flooring dimensionally stable. Each layer’s tendency to move across its own grain is resisted by the layer bonded to it at a right angle.
It is the single technical reason engineered is specified over concrete slabs, in condominiums and above radiant heat.

Terms this one depends on
- Engineered hardwoodFlooring that pairs a real hardwood wear layer with a 90° cross-ply core, which is what gives it dimensional stability over concrete, in condominiums and above radiant heat.
- Wear layerThe thickness of real hardwood above the core — what determines how many times a floor can be refinished.
- AnisotropicDescribes a material whose properties differ by direction — in wood, movement across the grain is significant while movement along it is minimal.
