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.

Frequently Asked Questions
1. What is an EPS cement sandwich panel?
It is a composite building material with two layers of fiber cement or calcium silicate boards sandwiching an expanded polystyrene (EPS) core. It is lightweight, fire-resistant, and provides excellent insulation.
2. What are the main advantages of using these panels?
The panels are 1/10 the weight of traditional bricks, offer Class A fire resistance, provide superior sound (40-45 dB) and thermal insulation, and can be installed much faster than traditional masonry.
3. Is the panel fire-resistant and waterproof?
Yes. The cement facings combined with flame-retardant EPS achieve a Class A fire rating. The closed-cell structure of the EPS core also ensures low water absorption, making it moisture-proof.
4. Can it be used for load-bearing walls?
These panels are primarily designed for non-load-bearing structures such as internal partitions and external curtain walls. For structural applications, they require integrated steel framing support.
5. What is the expected service life?
With proper installation and routine maintenance, EPS cement sandwich panels can last over 50 years under normal environmental conditions.
6. Can the dimensions be customized?
Yes, we support customization for various lengths and thicknesses (typically ranging from 50mm to 200mm) to meet specific project requirements.
