Abstract
A structural panel comprising a hollow frame defining a central opening, with the frame having secured to opposite sides thereof first and second facing panels. The opening within the frame receives a core which is of the same thickness as the frame, but which has a perimeter less than that defined by the opening so that the core is loosely positioned within the opening. The core is supported solely by the facing panels and is free of any direct connection to the frame, the core being connected to the frame only through the facing panels.
