a front layer fixed to the frame and covering a front surface of the core structure, and
a back layer fixed to the frame and partially covering a back surface of the core structure,

wherein the front layer is fixed to a front surface of the frame,
wherein the frame comprises a protruding lip protruding into the receiving opening, the protruding lip providing a seat for the core structure,
wherein the back layer covers opposed surfaces of the frame adjacent to the seat,
