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.

Technical Advantage:

A. Best heat insulation material to date.
B. Rigid and light weight.
C. Environment friendly.
D. Water, Moisture and sound proof.
E. Easy and Simple construction.

Panel System Structure:

A. Plain / Corrugated type skin.
B. Tongue and Groove connection.
C. Corner wall panel.
D. Fastener type with Camlock.

The following is a summary of the difference between polyurethane and polystyrene. It is important to note that Polyurethane was invented to improve the shortcomings of the Expanded polystyrene (EPS).
