Product Description
EPS Cement Sandwich Panel (also known as EPS Core Sandwich Panel or Lightweight Insulated Wall Panel) is a high-performance prefabricated building material composed of:
Outer Layers: Fiber-reinforced cement boards (or silicon calcium boards) for structural strength.
Core Material: Expanded Polystyrene (EPS) foam for thermal insulation.
Adhesive Layer: Special polymer-modified cement mortar for bonding.
This panel is widely used in residential, commercial, and industrial construction due to its lightweight, fire resistance, thermal insulation, and rapid installation benefits.
