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.

1. What is an EPS cement sandwich panel?
- Definition: A composite panel composed of two layers of fiber cement boards or calcium silicate boards sandwiching an expanded polystyrene (EPS) core material.
- Characteristics: Lightweight, thermal insulation, acoustic insulation, fire-resistant, corrosion-resistant, widely used in building walls, roofs, and partitions.
2. What are the advantages of EPS cement sandwich panels?
- Lightweight & High Strength: Weighs only 1/10 of traditional brick walls, reducing structural load.
- Superior Load-Bearing Capacity: Suspension capacity exceeds 1500N (≈153kg).
- Thermal & Acoustic Insulation: EPS core effectively blocks heat transfer and sound transmission.
- Fire Resistance: Cement facings combined with flame-retardant EPS typically achieve Class A fire rating (non-combustible).
- Rapid Installation: Modular design with prefabricated components allows effortless cutting/grooving, minimizing labor and time costs.
- Eco-Friendly: Recyclable materials with low embodied energy in production.
3. Disadvantages & Precautions
- Low Impact Resistance: Thin cement surface layer requires avoidance of impacts from sharp/heavy objects (ASTM D256 Izod impact test standard).
- Non-Load-Bearing: Restricted to non-load-bearing structures; requires steel framing support (EN 1993-1-1:2005 for structural steel design).
- Moisture Sensitivity: Prolonged exposure to humidity may degrade EPS properties; waterproofing measures are mandatory (EN 16047:2012 for sandwich panel moisture resistance).
- Dust Generation: Cutting during installation produces fine particulate matter; OSHA-compliant PPE (e.g., N95 masks) must be worn (OSHA 29 CFR 1910.134 respiratory protection).
4. Environmental Friendliness?
- Recyclability: Cement panels can be crushed and reused, while EPS (expanded polystyrene) can be recycled and pelletized.
- Production Process: No toxic substances are released during manufacturing, with carbon emissions significantly lower than traditional construction materials.
5. Maintenance and cleaning guidelines?
- Routine Cleaning: Wipe surfaces with water or neutral detergents.
- Periodic Inspection: Check joint seals and repair cracks promptly.
- Anti-Corrosion: Apply rust-proof coatings to exposed metal connectors.
6. What is the service life?
- Normal Conditions: Over 30 years (with proper installation and no extreme environmental damage).
- Risk Factors: Humidity, acid rain, or salt spray may shorten lifespan.
7. Typical applications?
- Common Uses:
- Factories, warehouses, logistics centers
- Temporary structures (site offices, exhibition halls)
- Agricultural greenhouses, livestock barns
- Noise barriers, container houses
- Unsuitable For: Load-bearing walls, submerged environments, or areas near high-temperature industrial furnaces.
8. Can dimensions and colors be customized?
- Dimensions: Most manufacturers offer custom lengths and thicknesses (standard: 50-200mm).
- Colors/Textures: Available with colored coatings or stone/wood-grain finishes.
9. Acoustic performance?
- Reference Data: 100mm thick panels provide 40-45 dB sound insulation, meeting general building requirements.
- Enhancement: Increase panel thickness or add sound-absorbing layers.
10. How to Improve the Thermal Insulation Performance of EPS Cement Sandwich Panels?
EPS cement sandwich panels consist of expanded polystyrene (EPS) foam cores with a closed-cell structure, which traps air and provides extremely low thermal conductivity, effectively reducing heat transfer. The cement facings offer structural support and surface protection, forming a lightweight insulated wall system suitable for both thermal and cold insulation applications.
Methods to Enhance the Thermal Insulation Performance of EPS Cement Sandwich Panels:
1. Increase the Core Thickness - A thicker EPS core improves thermal resistance (R-value), reducing heat transfer.
2. Optimize Joint Sealing—Apply expanding foam sealant to fill panel gaps, minimizing thermal bridging and improving overall insulation continuity.
11. Is the EPS cement sandwich panel itself moisture-proof?
Yes.
- Cement surface layer: Good waterproofing; can block liquid water penetration.
- EPS core material: Closed-cell structure, low water absorption rate.
12. Can it be used in seismic zones?
Yes - Flexible EPS core absorbs vibrations.
13. How long does it last?
50+ years with proper maintenance.
