Product Description
Introducing the EPS Cement Sandwich Panel, also known as the EPS Core Sandwich Panel or Lightweight Insulated Wall Panel. This is a superior prefabricated building material crafted for exceptional performance. It comprises:
- Outer Layers: Crafted from fiber-reinforced cement boards (or silicon calcium boards), ensuring unmatched structural strength and durability.
- Core Material: At its heart lies expanded polystyrene (EPS) foam, delivering remarkable thermal insulation properties.
- Adhesive Layer: Special polymer-modified cement mortar acts as a robust adhesive, providing enduring bonding strength.
This panel is a preferred choice across residential, commercial, and industrial sectors, celebrated for being lightweight, fire-resistant, and thermally insulating while enabling swift installation.

Frequently Asked Questions
1. What is an EPS cement sandwich panel?
A composite panel composed of two layers of fiber cement boards or calcium silicate boards sandwiching an expanded polystyrene (EPS) core material. It is lightweight, fire-resistant, and widely used for walls and roofs.
2. What are the primary advantages of these panels?
They are 1/10 the weight of traditional brick, offer superior thermal and acoustic insulation, achieve a Class A fire rating, and allow for rapid modular installation which saves labor costs.
3. Are the panels moisture-proof?
Yes. The cement surface layer provides good waterproofing to block liquid penetration, and the EPS core material features a closed-cell structure with a low water absorption rate.
4. Can they be used in seismic zones?
Yes. The flexible EPS core is designed to absorb vibrations, making it suitable for earthquake-prone areas compared to rigid traditional masonry.
5. What is the expected service life?
Under normal conditions and with proper installation, these panels have a service life of over 50 years with minimal maintenance.
6. Can dimensions and colors be customized?
Absolutely. Lengths and thicknesses (standard 50-200mm) can be customized, and surfaces can be finished with various coatings or textures like stone or wood grain.
