DYDs sandwich panel uses polyurethane foam as core, which is known as the best insulating material to date. The panels are produced through a discontinuous production line. Using a
hydraulic multiple bed press, a variety of pre-cut facings (various metal skin, glass wood, plasterboard, etc.) are placed into a jig where the polyurethane components are injected. This
method offers flexibility allowing different edge detail and locking mechanisms to be easily incorporated in the design.
