What is sandwich panel?

A sandwich panel is a modular construction material used for cladding buildings and structures. These panels consist of two layers that form the external structure, ensuring shape retention, weather resistance, and rigidity. They contain a core material that provides thermal insulation and soundproofing properties.

What types of sandwich panels are there?

The types of sandwich panels depend on their core material. The core can be made of polyurethane (PU/PIR), rock wool, glass wool, EPS foam, or other materials.

What are sandwich panels used for?

These insulated components are particularly suitable for the roofs and exterior walls of industrial buildings operating in low-temperature environments. Due to their lightweight nature, they are ideal for renovating building envelopes. They are also commonly used in cold storage rooms, warehouses, sports centers, shopping malls, as well as for insulation in new and renovated residential buildings.

☆Sandwich Panels for Exterior Walls

Exterior wall sandwich panels are designed for constructing the envelopes of residential buildings, schools, hospitals, industrial centers, or shopping malls. They can also be used for interior partitions requiring thermal insulation.

The effectiveness of these exterior wall panels largely depends on how they are joined together. The fastening system uses tongue-and-groove connections to ensure optimal protection against heat and moisture loss.

☆Roof Sandwich Panels

Roof sandwich panels differ from exterior wall panels in their requirements, as they must withstand heavy snow, rain, and other climatic factors.

They are secured to the structure using self-drilling screws to prevent leaks in rainy or humid conditions, often combined with sealed joints. This speeds up installation without compromising the insulation layer.

☆Cold Storage Panels

Sandwich panels can also be used for cold storage rooms or freezers that require thermal insulation. In these cases, the panels are designed with greater thickness than standard panels to withstand sub-zero temperatures.

To maintain the extreme temperatures required for preserving fresh food, special attention must be paid to the joints between the panels.

Sandwich panels are versatile building materials widely used in roofing, exterior walls, and cold storage facilities due to their lightweight, thermal insulation, and cost-efficiency. Ideal for industrial, commercial, and residential projects, they enhance energy efficiency and durability while speeding up construction. With options like PU, rock wool, and EPS cores, these panels meet diverse needs—from warehouses to refrigerated rooms. Their easy installation and low maintenance make them a top choice for modern construction. For high-performance insulation and structural strength, sandwich panels deliver unmatched value.
