raised panel

noun1

1. •
   A woodworking technique, primarily used in door design, that improves durability and allows wood to expand and contract with humidity, preventing warping and cracking (wood naturally shrinks and swells with temperature); while also adding depth or elegance (a traditional aesthetic that is historically rooted in classic architecture like Colonial and Georgian style); the raised center panel is set in a groove within the stiles and rails, allowing it to "float" and move independently without stressing the door structure.
