Cold Storage Metal Galvanized PU steel sandwich panels
PU steel sandwich panels are a type of construction material that is commonly used for building walls, roofs, and floors. They consist of an insulating core material, which is typically made of polyurethane (PU) foam, sandwiched between two steel-facing sheets. The steel facing provides strength and durability, while the PU foam provides thermal insulation and sound absorption. PU steel sandwich panels are known for their lightweight, high strength, excellent thermal insulation, and fire resistance properties, making them an ideal choice for constructing energy-efficient buildings. They are widely used in industries such as warehousing, cold storage, and construction.
The cost of PU steel sandwich panels can vary depending on factors such as location, material quality, and quantity ordered. However, some countries are known to offer more economical options when it comes to PU panels.
China is one of the leading manufacturers of PU panels and is known for its reasonably priced products.Ultimately, it is important to research and compare pricing and quality from multiple suppliers to ensure that you are getting the most economical option for your needs.
EPS (Expanded Polystyrene) sandwich panels are constructed with a foam core made of polystyrene, which is a water-resistant material. The panels are suitable for applications where they may be exposed to moisture or humidity without losing their properties. This makes them a good choice for coastal areas where they can be exposed to moisture due to proximity to the ocean.
Rock wool sandwich panels, on the other hand, are made of mineral wool and can absorb water if they are not properly sealed. While they have excellent thermal insulation and fire resistance properties, they may not be the best choice for an area that is very near to the ocean due to the risk of corrosion from salt water exposure.

Comparison of PU, Rock Wool, EPS panel
1. Polyurethane (PU) Panels:
- Thermal Insulation: Excellent
- Fire Resistance: Good
- Water Resistance: Good
- Sound Insulation: Good
- Durability: Excellent
Most Suitable Applications:
- Cold storage buildings and warehouses
- Food processing plants
- Pharmaceutical facilities
- Clean rooms and laboratories
- Prefabricated buildings
- Commercial buildings
- Residential buildings
2. Expanded Polystyrene (EPS) Panels:
- Thermal Insulation: Good
- Fire Resistance: Poor
- Water Resistance: Fair
- Sound Insulation: Fair
- Durability: Fair
Most Suitable Applications:
- Residential and commercial buildings
- Industrial sheds
- Office buildings
- Retail shops
- Warehouses
- Portable cabins
3. Rockwool Panels:
- Thermal Insulation: Excellent
- Fire Resistance: Excellent
- Water Resistance: Poor
- Sound Insulation: Excellent
- Durability: Excellent
Most Suitable Applications:
- Industrial and commercial buildings
- Hospitals and schools
- Public buildings
- Sound studios and theaters
- Power plants and refineries
In summary, PU panels are most suitable for applications where high thermal insulation, fire resistance, and durability are required, such as cold storage facilities and warehouses. EPS panels are suitable for applications that require good insulation but are not exposed to fire or moisture risks, such as residential and commercial buildings. Rockwool panels are suitable for applications that require high thermal and sound insulation and excellent fire resistance, such as industrial and commercial building, hospitals, and schools.
How big is a sandwich panel?
The width of the sandwich panel is usually 950 mm. The length of the sandwich panel can be adjusted according to the needs of each project, the most common dimensions being between 3 and 6 meters, but, in some cases, a maximum length of up to 16 meters can be reached. The thicknesses of these panels can vary enormously depending on the final application, the most common values being between 40 and 150-200 mm thick depending on the application.
The characteristics of sandwich panels for roofs differ from façade panels in that they will have to withstand large amounts of snow, rain, and other climatic factors.
They are fixed to the structure with self-drilling screws, to prevent leakage in case of rain and humidity, and are often combined with sealing joints, which speed up installation without sacrificing the insulation layer.
Sandwich panels are one of the most economical insulation solutions, with greater durability, shorter installation time, less need for maintenance, and greater capacity for acoustic and thermal insulation. In addition, they can be adapted to all building needs and typologies, with different types of panels for each case.
Sandwich Panel Insulation Type Selection Guide
The functions and needs of every building are different. Sandwich panel choice thus varies according to the thermal, acoustic, and hydro insulation and fire resistance needs of your building. Selecting the insulation core in accordance with the need of your building positively affects the performance you will obtain from the sandwich panel.
You can select the insulation material suitable for the features and needs of your building from the Sandwich Panel Selection Table we prepared for you.
| Temperature range | Thickness of cold room panel |
| 0 ºC - - 5 ºC | 75mm thick |
| -10 ºC - -18 ºC | 100mm thick |
| -25 ºC - -36 ºC | 150mm thick |
| -36 ºC lower | 200mm thick |
