1. What is 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 40-45dB 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 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.
