Description
1. Cold Room Panel Type
At our factory, we offer two types of sandwich panels for cold room storage: PU panels and PIR panels. We have two imported production lines dedicated to manufacturing these panels.
A sandwich panel consists of three layers: the core, and two side skins. The core is made of different raw materials, depending on the type of panel. And, we offer a wide range of steel materials for the surface.
2. What are the differences between PUR and PIR panels?
PIR and PU panels are two different sandwich panels from different raw materials.
Features of cold room panel:
- Broadest range of cold room and walk-in freezer options.
- Dependable and extremely energy-efficient solutions.
- Extended lifespan, minimal operating and maintenance expenses.
- Ease and speed of cold storage installation.

3. How To Choose the suitable panel for cold room?
#1 Panel Thickness
We offer sandwich panels in varying thicknesses, ranging from 50mm to 200mm. The appropriate thickness can be selected based on factors such as temperature, room size, and other requirements.
| Panels thickness | Heat transfer coefficient(w/m2·k) | Temperature difference inside and outside cold room | Suitable temperature for cold room |
| 75mm | 0.267/0.3 | 40°C | -5~25°C |
| 100mm | 0.2/0.23 | 50°C | -15~25°C |
| 150mm | 0.133/0.15 | 70°C | -25~25°C |
| 180mm | 0.11/0.125 | 80°C | -35~25°C |
| 200mm | 0.1/0.113 | 90°C | -50~25°C |
#2 Surface Material
The surface steel can be chosen according to the application. We offer a variety of steel options to meet your project requirements. For PPGI (color plate), we use Baosteel, a renowned steel manufacturer in China. Our stainless steel(SUS304) has excellent anti-corrosion properties and is suitable for coastal cities.
For example, Jack need a cold storage to freeze fish. So he bought the panel with stainless steel and aluminum steel.
Stainless steel on inner side — anti-rust, durable.
Aluminum steel on outer side — save money, looks pretty.
4. Cold Room Panels Installation
#1. Installation for cold room PU panel with Cam lock system
