FAQ

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.
