Types of Sandwich Panels Based on Core Material

The core material determines the panel's properties, such as insulation, strength, and fire resistance. Common core materials include:

• Polyurethane (PUR) or Polyisocyanurate (PIR) Foam:

  • Excellent thermal insulation.

  • Lightweight and fire-resistant.

  • Used in cold storage, roofing, and wall cladding.

• Polystyrene (EPS or XPS):

  • Cost-effective and lightweight.

  • Good thermal insulation.

  • Commonly used in prefabricated buildings and modular construction.

• Mineral Wool:

  • Fire-resistant and soundproof.

  • Used in fire-rated walls and ceilings.

• Honeycomb Core:

  • Lightweight and high strength.

  • Used in aerospace, automotive, and high-performance applications.

• Aluminum or Steel Core:

  • High strength and durability.

  • Used in industrial and structural applications.
