When it comes to producing coldrooms, the best material out there is sandwich panels. sandwich panels are highly versatile in regard to coldrooms. They are mainly used in: coldroom’s doors, walls and roof. The economical price of coldroom sandwich panels adds in to all the other advantages of this structure.
Obviously, the efficiency of a refrigerator depends on the insulation of the space inside it and the reduction of heat transfer between the inside and outside as much as possible. The following changes play an important role in insulation.
One of the challenges of coldrooms, whether during installation or operation, is the issue of airlock and proper connection of the sandwich panels to each other. Although the skill and precision in installation is also effective in overcoming this challenge, but the plugs and tabs should be produced in a standard and systematic manner in terms of geometric shape design, accuracy in measurements, having no distortion and the material of contact surface coating. The best way to improve the airlock quality of coldrooms is to reduce the number of joints between the sandwich panels. For the first time in Iran, AryaBaron succeeded in producing wide coldroom sandwich panels with a width of 120 cm and by doing so resolved the challenges of coldroom panels. When the walls and roof of a coldroom are covered with 120 cm wide sandwich panels, the number of joints is reduced by 20% compared to the traditional 1-meter-wide sandwich panels. In other words, the challenge of keeping the coldroom airtight is reduced by 20% without any changes just by using a wider panel.
Another advantage of 1.2-meter-wide sandwich panels is the optimal use of space for trucks and trailers, resulting in a 40% reduction in transportation costs.
The loadable width of the floor of a trailer is 2.5 meters, and when two rows of 1.2-meter-wide sandwich panels are loaded next to each other, 2.4 meters of width is used. On the other hand, if we use two rows of traditional sandwich panels with a width of 1 meter it will occupy a width of 2 meters; therefore, a space with 40 cm wide and 12 meters long and 2.5-meter high will remain unoccupied.
Strength is an essential factor for a high0quality sandwich panel in transportations and in high pressures. In order to gain this strength, when installing the top and the bottom sheet to the plug, it is necessary that the top of the top sheet and the bottom sheet are placed inside the injected foam. In Arya Baron sandwich panels, this important point has been observed in a systematic and appropriate manner.
In the Arya Baron sandwich panel, the upper and lower parts of the tenon is rolled the form of a jag to distort the sheet and create a smooth and integrated surface for better contact with the mortise.
The geometric design of the tenon and mortise (tips) should be designed in a way that after connecting the two panels to each other, these two parts have the highest contact surface with each other.
To improve this connection, thin polyethylene cloud layers are also used during installation.
Silicone glues are also used to improve airtightness during installation, but it should be noted that these glues have good adhesion to paper surfaces and do not adhere to plastic or greasy surfaces.
Coldroom sandwich panels can be divided into different categories on several bases. One of these categories is based on the material of the sandwich panel’s insulation layer. For example, panels which have polyurethane foam as their core layer are called polyurethane coldroom sandwich panels. But the sandwich panels that are used to cover the wall and roof of the coldrooms have different technical specifications according to the type and application of the coldroom. These panels can be classified into 4 groups based on the type of coldroom and its usage:
As the temperature decreases in the above coldrooms, the energy consumption increases dramatically. Here we should look for a fundamental solution to resolve this problem for good. AryaBaron suggests using coldroom sandwich panels. The application and special properties are two factors that determine the most suitable insulation foam and metal sheets for coldroom sandwich panels.
The price of each square meter of these sandwich panels varies according to their application and the customer’s demands. These sandwich panels are used for various structures such as industrial factories, construction of freezing tunnels for large buildings, refrigeration in laboratories, hospitals, etc., and the sandwich panel that should be used for each of these structures has special technical features and characteristics. As a result, it’s not possible to accurately state the price of coldroom sandwich panels.
The structure of the sandwich panel, the type of insulation layer and its thickness, the type of sandwich panel covering sheets and their measurement, as well as the quality of the construction of these sandwich panels all affect the price of one square meter of it.

Investigating the positive features of cold storage sandwich panels
Features of cold storage sandwich panel
In the past, different traditional materials were used to insulate the walls of coldrooms, but with the passage of time and industrial developments, with the help of sandwich panel walls and their insulation property, energy consumption in coldrooms can be prevented in a more efficient way. The most important features of coldroom sandwich panels are:
Coldroom sandwich panel structure
The best insulating foam for these sandwich panels is injected polyurethane foam with a density of 40 kg/m3. The polyurethane used to produce these sandwich panels is light, stable and has certain physical properties. The special design of these coldroom sandwich panels significantly reduces the electricity costs of the coldroom. The characteristics of the insulating layer of the coldroom sandwich panels are:
These coldroom sandwich panels are designed to connect to each other in the form of a tenon and a double mortice. These rabbets lock in each other to create an integrated wall. Panel locks are used to ensure that the panels fit together perfectly so that there will be no seams. These locks are placed inside the sandwich panels as rabbets to lock together. The purpose of this system is to minimize the possibility of air passing and changing the coldroom temperature.
Aluzinc is often used to cover coldroom panels. Aluzinc is a steel that is coated with zinc and aluminum, and this combination has led to an increase in the resistance of Aluzinc. Therefore, to increase the strength and resistance of coldroom sandwich panels against environmental challenges, rust, corrosion, etc., Aluzinc steel is used as a coating of sandwich panels. PIR non-flammable polyurethane insulation foams are used in the structure of coldroom sandwich panels, and this is yet another significant advantage of these panels.
In order to connect the panels to each other as well as possible and to ensure the durability of the connections in earthquakes, for the first time in Iran AryaBaron produced a cold storage sandwich panel equipped with locks in the Continuous line. The interlocking panels are easily airtight together and maintain a strong connection even during earthquakes.
AryaBaron also produces and markets lockable panels to connect the walls to the ceiling for better ventilation and fast installation.
One of the most important advantages of these panels is resistance to moisture, heat and sound transmission. To build a cold storage or freezing tunnel in a building with traditional materials, a lot of time, money, energy and manpower is needed, while with the help of coldroom sandwich panels, it is easy to speed up the execution of a coldroom project. Among the other advantages of cold storage sandwich panels, the following can be mentioned:
One of the stages of insulating the roof and walls of a cold storage or freezing tunnel is the installation of sandwich panels, which is of great importance. If the installation process is not performed correctly and the necessary standards are not met, the project will suffer a lot of damage. Coldroom sandwich panels should be installed and properly sealed with flushes according to the procedures.
Therefore, although the cold room sandwich panel installation process is simple, it must be done by a skilled sandwich panel installer. AryaBaron factory has a long history and experience in the field of selling all kinds of roof, wall and coldroom sandwich panels. For more information and advice from our experts, you can contact us through the numbers listed on the site.
All kinds of sandwich panels have a simple installation process and these panels can be installed in a short period of time. Since the main purpose of using a coldroom panel is to prevent energy loss, special equipment and fittings are used during the installation of these panels to minimize the possibility of air passing through the walls of the coldroom.
Polyurethane foam is often used for the insulating layer of sandwich panels. The insulation layer of sandwich panels is generally made of polyurethane, rock wool, and polystyrene. But among all of them, polyurethane has stronger insulating properties. Since the main reason for using sandwich panels in coldrooms is to prevent energy loss, the best foam that can be used in their structure is polyurethane.
The suitable thickness of the insulation layer for coldroom sandwich panels is generally between 8 to 20 cm. The greater the thickness of this layer, the greater the sandwich panel’s ability to maintain the coldroom temperature. The material used in these sandwich panels is Aluzinc, galvanized and aluminum. The thickness of coldroom sandwich panel sheets is between 0.5 to 0.7 mm. The length of the sandwich panels varies from 2 to 13.60 meters according to the customer’s request
For the first time in Iran, Arya Baron produced sandwich panels for refrigerators equipped with refrigeration locks in the Continuous line in order to better connect the panels to each other and for the durability of the connections in earthquakes. Locked panels are easily air-locked to each other and even in strong earthquakes they maintain a strong connection.
Arya Baron also produces and markets locked panels for the best airlock and fast installation according to the order to connect the walls to the ceiling.
As one of the spaces in which the construction of coldroom sandwich panels is very popular, we can mention all kinds of coldrooms and frozen tunnels. The main application of these sandwich panels is sealing and insulating all kinds of cold storages. Coldroom sandwich panels are also used for building coldrooms in large buildings, warehouses, ice cream factories, industrial factories, etc. Other uses of these panels are:
coldroom Sandwich Panel is used to prevent the increase of energy consumption in coldrooms and cold storages. In very low temperatures of coldrooms, especially below zero coldrooms, energy consumption may become more than usual. To prevent this energy loss, the walls and roof of coldrooms are covered with a cover called coldroom sandwich panel. These sandwich panels with their unique features are produced for the country’s needs in the refrigeration industry and reducing energy consumption. The structure of coldroom sandwich panel is similar to roof sandwich panel and wall sandwich panel. The only difference is that the thickness of the sheets and the density of the insulation layer in these sandwich panels are more than other types of sandwich panels.
Coldroom sandwich panels include a core layer called insulation layer, which is covered on both sides by two metal layers. Coldroom sandwich panel manufacturers, including AryaBaron factory, are trying to make these panels in such a way as to prevent air from entering and leaving the cold storage. These panels are widely used for various coldrooms such as below zero, above zero coldrooms, industrial factories and generally in the refrigeration industry.
