Sandwich panels offer significant advantages in modern construction projects, both in terms of aesthetics and functionality. One of the most important features of these panels is their insulation property. Heating options enhance the energy efficiency of buildings and significantly improve indoor comfort.

1. Polyurethane (PUR) and Polyisocyanurate (PIR) Foam

They are commonly used insulation materials in sandwich panels. Both materials provide excellent thermal insulation and are ideal for energy efficiency.

  • Polyurethane (PUR) Foam: Polyurethane foam provides excellent insulation due to its low thermal conductivity. Additionally, its lightweight structure reduces structural load and offers ease of installation. Polyurethane is typically recommended for cold storage facilities and buildings where energy savings are critical.
  • Polyisocyanurate (PIR) Foam: PIR foam is stronger than PUR foam in terms of fire resistance. Its resistance to high temperatures makes it recommended for industrial facilities and buildings where fire safety is important.

2. Stone Wool

Stone wool is an insulation material obtained by melting natural stones at high temperatures and spinning them into fibers.

  • Advantages of Stone Wool: Stone wool offers excellent fire resistance and withstands high temperatures. Additionally, it exhibits superior performance in sound insulation. Thanks to these properties, it is particularly preferred in structures where fire safety and acoustic comfort are important.
  • Applications ofStone Wool:Stone wool insulated sandwich panels are commonly used in industrial facilities, residential buildings, and commercial structures.

Extruded Polystyrene (XPS) and Expanded Polystyrene (EPS)

These are two different types of polystyrene known for their insulation performance.

  • XPS: XPS has a low water absorption rate due to its closed-cell structure. This feature makes it ideal for use, especially in damp and water-exposed areas. It enhances structural durability with high compressive strength.
  • EPS: EPS is a cost-effective insulation material and has a wide range of applications. It stands out for its lightweight structure and ease of handling. While its thermal insulation performance may not be as high as XPS, it offers cost-effective solutions.

4. Vacuum Insulation Panels (VIPs)

Vacuum Insulation Panels (VIPs) are one of the materials that offer the highest thermal insulation performance. These panels, produced using vacuum technology, have extremely low thermal conductivity.

  • Advantages of Vacuum Insulation: VIPs provide superior insulation despite being much thinner compared to other insulation materials. With these features, they are an ideal solution for projects where energy savings are critical and space is limited.
  • Applications of Vacuum Insulation: VIPs are used in buildings requiring high-performance energy insulation, in cold chain logistics, and in industrial applications requiring high technology.

The insulation materials used in sandwich panels significantly increase the energy efficiency and indoor comfort of buildings. Materials such as polyurethane, polyisocyanurate foams, stone wool, XPS, and EPS each have different advantages suitable for various applications. Additionally, there are advanced technology solutions such as vacuum insulation panels that provide high-performance insulation tailored to specific needs. The selection of the right insulation material should be based on the project’s requirements and budget.
