Hey there! As a supplier of cold room panels, I often get asked about what these panels are made of. So, I thought I'd break it down for you in this blog post.
The Core Materials
Let's start with the core of the cold room panels. The most common material used for the core is polyurethane (PU). PU is a fantastic insulator. It has a really low thermal conductivity, which means it can keep the cold air inside the cold room and the warm air outside. This is super important because it helps in reducing energy consumption. When your cold room doesn't have to work as hard to maintain the low temperature, you save on electricity bills.
The manufacturing process of PU - core panels involves injecting a liquid polyurethane mixture into a mold. As it expands and cures, it forms a rigid foam structure. This structure is not only great for insulation but also provides good structural integrity to the panels. You can find our Cam Lock PU Panel which is a popular choice among customers. The cam - lock system makes it easy to install and disassemble the panels, which is really handy if you need to move or modify your cold room.
Another material used for the core is polystyrene (PS). PS is also a good insulator, but its thermal performance is not as good as that of PU. However, it's generally cheaper. So, if you're on a tight budget and don't need extremely low temperatures, PS - core panels can be a good option. They are lightweight and easy to handle during installation.
Extruded polystyrene (XPS) is a type of PS that has better moisture resistance compared to regular PS. It has a closed - cell structure, which makes it less likely to absorb water. This is important in cold room environments where moisture can cause problems like mold growth and reduced insulation performance.
The Outer Layers
The outer layers of cold room panels play a crucial role too. They protect the core material and give the panels a finished look. One of the most commonly used materials for the outer layers is galvanized steel. Galvanized steel is steel that has been coated with a layer of zinc. This coating protects the steel from rust and corrosion. It's strong and durable, which can withstand the wear and tear in a cold room environment. Whether it's the impact from handling goods or the constant temperature changes, galvanized steel outer layers can hold up well.
Aluminum is another option for the outer layers. Aluminum is lightweight, which makes the panels easier to install. It also has good corrosion resistance. Unlike steel, aluminum doesn't rust. It forms a thin oxide layer on its surface that protects it from further oxidation. This makes it a great choice for cold rooms where there might be a lot of moisture or where the panels are exposed to certain chemicals.
Stainless steel is also used for the outer layers, especially in applications where hygiene is a top priority. Stainless steel is resistant to stains, corrosion, and bacteria. It's easy to clean, which is essential in food storage cold rooms or pharmaceutical cold rooms. You don't have to worry about any contaminants sticking to the surface of the panels.
Insulation Thickness
The thickness of the insulation in cold room panels is an important factor. For most general - purpose cold rooms, a thickness of around 100mm is quite common. Our 100mm Insulated Cold Room Panels are designed to provide a good balance between insulation performance and cost. A thicker panel will generally provide better insulation, but it will also be more expensive and might take up more space.
If you need to maintain extremely low temperatures, say for storing frozen goods, you might want to consider thicker panels, like 150mm or even 200mm. On the other hand, if you're just using the cold room for storing items at slightly chilled temperatures, a thinner panel might be sufficient.
Other Considerations
When choosing cold room panels, you also need to think about the fire resistance of the materials. Some panels are treated with fire - retardant chemicals to meet safety standards. This is especially important in commercial and industrial cold rooms where there are strict fire safety regulations.
The acoustic performance of the panels can also be a factor. If your cold room is located in an area where noise is a concern, you might want to choose panels that have good sound - insulating properties. Some panels are designed with special acoustic layers to reduce the noise from the refrigeration system.
