foam-panel-guaranteed-true-flat-lightweight-strongCompare Sing Sandwich panels to other sandwich panel core materials.

Sing Core Foam Choice: Our stock sandwich panels feature extruded polystyrene as rigid insulation but may be upgraded to polystyrene to meet your specifications at an additional charge.

Sing Edge Option: Sing Sandwich panels have no solid edge. In the event that you require wood edges (or edges and/or implants of plastic or aluminum) Sing Panels would be better suited for your use.

Sing Sandwich vs. Sing Panel: Our regularly stocked and most in-demand honeycomb panels are our plywood panels and aluminum metal panels which are lightweight and stronger than steel pound for pound.

How to BuyMetal Composite Sing Core panels are true straight, light and strong.
