A Supreme Insulated Panel Systems SIP are manufactured by precision laminating a sheet of MgO board on either side of an EPS foam core. This creates an extremely strong and versatile composite panel that can be used for many different applications. MgO board is the structural component and EPS foam is the insulating component of the panel. Supreme Insulated Panel Systems uses a proprietary MgO board. It is available in different thicknesses and dimensions for varying applications. The density of EPS foam can also be altered to increase or decrease R-Value to suit any application, be it a regular residential house or a cold storage facility.
