E-Lite patented SIP's (structurally insulated panels), provide a visionary twist on traditional SIP's, which use expanded polystyrene or other petroleum based cores. E-Lite products are environmentally friendly, composite panels, that are light weight yet incredibly strong, because they copy nature's design, by using recycled paper that is expanded and dried, to create the honeycomb core - a fire retardant insulator and sound barrier. Suitable for exterior and interior walls, partitioning, cladding, furniture, doors, ceilings, shop fitting, and more.
