How to Choose the Right Rock Wool Sandwich Panel for Your Needs

Understanding Sandwich Panels

Sandwich panels are widely used in construction for their excellent insulation properties and structural strength. They consist of three layers: two outer metal sheets and a core material that determines their performance characteristics.

Types of Sandwich Panel Core Materials

Rock Wool Sandwich Panels

Rock wool panels offer superior fire resistance (up to 4 hours) and excellent thermal insulation (thermal conductivity of 0.038-0.045 W/mK). They are ideal for industrial buildings, cold storage facilities, and fire-sensitive applications.

EPS Foam Sandwich Panels

Expanded Polystyrene (EPS) panels provide good thermal insulation (0.033-0.037 W/mK) at a lower cost. However, they have limited fire resistance and are not suitable for high-temperature environments.

Polyurethane Sandwich Panels

Polyurethane panels offer the best thermal insulation (0.019-0.023 W/mK) but are more expensive. They are commonly used in refrigerated warehouses and climate-controlled buildings.

Metal Carved Panels

Metal carved panels focus on aesthetic appeal and durability rather than insulation. They are often used for decorative facades and architectural features.

Key Selection Criteria

Factor Rock Wool EPS Foam Polyurethane Metal Carved
Fire Resistance Excellent (A1) Limited (B1-B2) Good (B1) Varies
Thermal Insulation Good Good Excellent Poor
Sound Insulation Excellent Fair Good Poor
Cost Medium Low High Varies

Application Recommendations

  • Industrial Buildings: Rock wool for fire safety
  • Cold Storage: Polyurethane for best insulation
  • Temporary Structures: EPS for cost efficiency
  • Architectural Features: Metal carved for aesthetics

Installation Considerations

Proper installation is crucial for panel performance. Consider:

  1. Structural support requirements
  2. Sealing methods for air tightness
  3. Expansion joint placement
  4. Compatibility with other building materials
