Below are the FAQs on cold room panels you should know right now. 

What are the features of the cold room panels from Sunnyda?

Thermal and humidity insulation 

The optimum thermal and humidity insulation for cold storage facilities is provided by sandwich panels. For commodities that must be kept at a specified temperature, sandwich panels limit heat loss or gain between indoor and outdoor spaces.

Cold storage sandwich panels minimize condensation by insulating the temperature and humidity pressure differential.

As a result, the structure is more resistant to mold and deterioration.

Water and airtight panels 

Joint features on Sunnyda Cold Storage Sandwich Panels ensure that the panels are assembled correctly, which helps prevent air and water leakage. You now have full control over the heating and cooling systems in your building, which will significantly improve its energy efficiency.

What are the types of joints used in making cold room panels for sale?

When it comes to the success of your installation, these joints can make or break the process.

There is no excuse for not being familiar with the many types of joints available for PU and other panels in a cold room. You can make better selections and get the results you want if you have enough panel joints.

Let’s take a look at each one:

Concealed fixation joint 

Exterior cladding panels are the most prevalent place to find concealed fastening seams. The panels are fastened together with invisible fasteners. There will be no visible screws after the panels are attached.

It’s easy to use the hidden fixing joint. It’s where the tongue and groove connect. With an overlapping design, an insulated panel shields it. 

Visible fixation joint 

The visible fixation joint is yet another type of tongue and groove joint that is well-known. On the other hand, the focus is glaringly visible in this joint. As a result of its dependability and the convenience with which it can be installed, it is utilized in a wide variety of buildings and cold rooms.

During the installation of a visible fixation joint, the screws should not be overtightened, since doing so could damage the surface of the panel. When creating a cold chamber, you have the option of using either a visible fixation joint or the labyrinth junction illustrated in the figure.

Visible fixation cold room panel joint

The visible fixation joint in the cold room is referred to as the visible fixation cold-room joint. This material is commonly used to make polyurethane panels for cold rooms. With an intricate design, the Labyrinth joint was named. The tongue and groove is more stable because of the labyrinth connection and the PU panel for cold room. Thus, cold room air leaks are avoided.

In this junction, you may want to experiment with several types of sealants, depending on the temperature and environment. Cold-room seams that are visible in cold room PU panels for sale used in cold rooms have additional advantages, such as the following:

  • Because of its unique design, there is less possibility of air leakage.
  • Frozen parts of the labyrinth are walled off from the outside world. Decrease in the amount of condensate as a result
  • This type of joint aids in the proper sealing of the cold room, preserving the freshness of the products for clients.
  • Improved joints would help if your items are kept fresher and have a better reputation in the industry.

Hermetic joint

The best hermeticity can be achieved using the hermetic joint. Cold room PUF panel suppliers also utilize it to seal the cold room fully. It has a joint between two females.

Additional flashing and building site space are required by the installer to achieve proper hermetic junction installation. The best result is achieved when the entire wall seems to be a single panel sandwich panel for cold rooms with no visible joints. Airtightness and freshness are important considerations when packaging a product.

What are the commonly used types of cold room panels?

Each structure has a specific function and set of needs. Choosing the right cold room panel for your project depends on your needs in terms of thermal, acoustic, water, and fire-resistant features. Make sure you choose the right insulating core for your sandwich panel to get the most out of it.

In order to get the right insulation for your construction, you can use the cold panel selection table from the Sunnyda catalog.

Polyurethane (PUR)

It is manufactured by mixing polyol and isocyanate in a high-pressure mixture with catalytic components.

Polyurethane’s closed-cell structure provides both thermal and water resistance. Bacteria were not found in any kind! One of its mechanical advantages is its high compressive strength.

Polyisocyanurate (PIR)

An important macromolecular structure known as polyisocyanurate is generated during the foam’s chemical reaction. In terms of fire resistance, polyisocyanurate rigid foam is superior to polyurethane. If a fire breaks out, polyurethane gives up more smoke. Well, they are still strong insulated wall panels cold rooms could use. 

Rockwool or Mineral Wool

Mineral wool is the preferred word for the fibers produced by melting inorganic rocks and other inorganic oxides. Due to its fibrous nature, an open-cell mineral wool product is perfect for sound and fire resistance. The thermal resistance of PIR and PUR is superior.

In our fully automated manufacturing facilities, mineral wool cold room wall panels are sliced perpendicular to their surface. Consequently, the pressure resistance and mechanical value of the panel have been improved.

It’s ideal for structures that need strong sound insulation, are susceptible to fire, or contain flammable/explosive materials.

Expanded Polystyrene (EPS)

Thermoplastic EPS is created from petroleum-based expanded polystyrene. To begin, the micro-granular polystyrene raw material is inflated with water vapor. The granules are inflated using pentane gas. Polystyrene granules make a tight bond and stick to the mold when expanded. Expanded polystyrene may now be cut into sheets after being made into blocks.

Pentane gas takes the place of air at the conclusion. Because of the dry, impermeable air trapped in their tiny pores, EPS sheets are excellent insulators.

Expanded polystyrene (EPS) is the lightest and most effective thermal insulating material available (EPS). You can get different cold room panel thickness with such materials. 

Neopor cold room panels

Neopor insulated panels are preferable to polystyrene ones (EPS). In the same manner, as before, graphite replaces wood as the raw material. In comparison to EPS, it has a higher R-value per inch (4.5).

The less permeable Neopor panels, on the other hand, enable optimal performance and cost savings.

Compressed straw cole cold room panels 

Environmentally friendly straw IPs are becoming increasingly popular.

These coolroom panels are made from agricultural waste straw. As a result, the panels with lower R-values are heavier. Many cold room panel manufacturers are now trying to adopt such new methods right now. 

What are the benefits of buying cold room sandwich panels?

Easy and quick to setup

A wide range of sizes, types of insulation, and colors can be found in continuous line cold room panels to match your business.

Because there are so few seams, cold room panels are simple to install, even on large surfaces. Because of improved, more efficient transportation and mechanical lifting equipment, it takes less time to transport and clad. Because of the quickness with which you completed your task, you saved time.

Better thermal insulation

Using thermal insulation helps keep heat from escaping while also lowering the amount of energy required to do so. The sandwich panel is a good alternative for thermal insulation.

Thermal insulation is provided by a sandwich panel comprised of PUR, PIR, EPS, or mineral wool. Using cold room panels for thermal insulation reduces mold and humidity caused by heat transmission and condensation. Thermal insulation value, load-bearing ability, and regional conditions all play a role in this.


Choosing the right sandwich panel might save you both time and money in the long run. To minimize the impact on daily operations, it may be installed fast and easily. By disassembling and recycling panels, you can save money and time.

Transport and building costs can be significantly reduced. They also save money because of their long-term structure.

Cold room panels are simply a fast, appealing, and cost-effective solution.

Stylistic cold room panels 

Your building’s exterior is a visual representation of your aims and goals. So, our sandwich panels for your buildings are constantly updated with fresh concepts. For the sandwich panels, which can be placed in any way but straight up and down, a broad variety of colors are available. 

Additionally, sandwich panels can be used to create interiors that are as unique as their exteriors.

Fire-resistant cold room material

If you select the appropriate sandwich panel for your building, you will be able to slow the spread of fire both inside the building and to the areas immediately surrounding it, which will keep both people and property safe.

When it comes to fire protection, use sandwich panels that include Rockwool.

Quiet cold rooms

In order to mitigate the negative impacts that noise has on humans, unwanted noises need to be muffled, and noise levels in noisy environments need to be brought down.

Panels made of acoustic material that are sandwiched together and attached to the ceiling and walls of a building can reduce noise levels, making the workplace more pleasant and conducive to productivity.

What is the size of cold room construction materials?

In the military, agricultural, prefabrication, building site, cold rooms, and silos, sandwich panels are widely employed. Sandwich panels can be made to any length you require based on your needs.

When establishing the size of sandwich panels, the thickness of the insulation should be taken into account. Insulation must be selected in accordance with the building’s standards, including the type and thickness of its core.

The thickness of Sandwich Roof Panels and Sandwich Wall Panels for your building’s roof and walls might vary depending on the type of insulation used. Mineral wool, expanded polystyrene, and PUR/PIR.

Mineral wool insulation thicknesses range from 50 to 150 mm for acoustic panels, whereas PUR/PIR insulation thicknesses range from 80 to 200 mm for cold storage panels.

Why should you use aluminum honeycomb cold room panels?

Despite its lightweight, this material is incredibly strong and has excellent stiffness, stability, and wind resistance.

Because of its lightweight, strength, and stiffness, this panel is widely used for exterior wall decoration. However, aluminum honeycomb weights just five times as much as steel honeycomb. It’s only 6 kg/m2 to have a 15mm aluminum honeycomb with different aluminum sheet thicknesses on top and bottom. Using honeycomb core material is more durable, less prone to bending, and more capable of compressive strength. 

A number of its properties make it superior to the aluminum-plastic plates and aluminum veneer, including a higher wind pressure rating, rigidity, and flatness. Large honeycomb plates can be flattened to an incredible extent.

Excellent noise, heat, and fire resistance, as well as seismic resistance

Because it is divided into numerous compartments, the sandwich panel’s aluminum honeycomb core effectively limits air movement, heat, and sound waves. For sound frequencies ranging from 100 to 3200 Hz, aluminum honeycomb panels have a thermal conductivity of 0.104-0.130W/M.K. 

Energy absorption ranges from 150 to 3500 KJ/M2, making it a good choice for reducing energy consumption in buildings. On metal veneer or aluminum-plastic roof panels, it is feasible to reduce the volume of rainfall.

The ability to maintain a vibrant and long-lasting look

Panels of honeycomb insulation are available in a variety of shapes and sizes, and they’re easy to clean.

The gloss and overall appearance of honeycomb sandwich panels made of aluminum are stunning. It can carry weight, keep heat in, and extinguish a fire, plus it’s water-resistant. It’s easy to set up, fast to build, and long-term useful. 

An everyday building material that also has the potential to be environmentally friendly. The material can also be used to make furniture and internal wall divisions, in addition to being used for wall panels. The ceiling and partition walls of an air-clean room, as well as cold storage and activity rooms, are just a few examples.

Which is better for a cold room between polystyrene and rock wool panels?


A fire-resistant sandwich panel’s best material is rock wool. All that’s needed are some screws and a screwdriver for installation, and you’ll be done in a jiffy. At the national level, the goods have passed tests for product quality and the use of fire-resistant ornamental materials.

Upper and lower steel plates are 0.4-0.8 mm thick. You have the option of using stainless steel, coated steel, or galvanized steel.

It’s common to utilize a core of rock wool that weighs 120-150 kg/m2.

Surface protection for steel plates with a polymer-based PVC film.

In today’s construction, thermal insulation is a new building material. Rock wool board and new polystyrene panels are also common in the thermal insulation business. If rock wool sandwich panels were replaced by polystyrene sandwich panels, which would be the better option?

  • Retardant to Flammability

Combustible due to the organic polymers used in the construction of EPS. Construction raises a number of fire safety issues and is inherently more fire-prone. The flammable faults can be efficiently addressed, but not eliminated. Inorganic basalt is used to construct the rock wool board. Combustion index A1 means there are no fire hazards in construction.

  • The rate at which water seeps into the insulation

Rock wool, on the other hand, is an inorganic fiber with a high water absorption rate, and polyphenyl board is a foamy plastic with a low water absorption rate. Alternatively, you can apply a hydrophobic layer of bonded mortar and plastering mortar to the surface of rock wool board.

  • Setting up

Polystyrene and rock wool sandwich panels can be bonded using the point frame method; however, because rock wool is a fibrous plate, the heavier bonding cement can’t be used, hence the full bonding process is employed when needed. At least 40% of the surface must be bonded. A minimum of seven anchorage nails per square should be used for the first seven layers of the rock wool panel, and nine anchorage nails per square for the remaining layers.

Why does magnesium cold room material get more preference nowadays?

  • Good fire resistance

Magnesium burns for only a few seconds at a time since it is an inert substance. MGO panel becomes fireproof and non-flammable at temperatures ranging from 800°C to 1200°C, earning an A1 grade. With a strong keel partition system, magnesium panels can withstand a fire for three hours. A substantial quantity of heat may be taken up by it during burning, therefore minimizing the increase in temperature.

  • Can tolerate the corrosive effects of water

MGO insulated panels are not affected by condensation droplets or wet air. There is no moisture absorption or halogen return even if it is submerged in water for a few days. The water permeability of the MGO panel was shown to be ineffective.

  • Lightweight and resistant to damage.

Over 60% of the construction load is reduced and 5-8 % of wall space is increased by using magnesium board. A lightweight structure can resist earthquakes and save money on the foundation and the main body.

  • Increased physical toughness 

Because of their rigidity and toughness, magnesium sandwich panels offer high impact, compression, tensile, and fracture resistance. At 322 kgf/cm2 and 25 Mpa, the flexural strength is impressive.

  • Environmentally friendly

MGO color steel sandwich panel is appropriate for use in the building industry since it is non-toxic and odorless in the event of a fire. In the absence of trash and pollution, the ecosystem is better preserved. The surface of this sandwich panel is not floured. Because of its fine-hole structure, it has the ability to control the temperature in the room or workplace.

  • Conservation of energy as well as protection from fire

MGO paneling is characterized by its inorganic components, small pore diameters, and compactness. It has a thermal conductivity of only 0.216 w/cm.k, compared to lime-sand brick and stone’s 1.1 w/cm.k. As a bonus, it saves energy and keeps the air cleaner for longer.

How do different cores of cold room panels compare?


Expanded polystyrene (XPS) and polyethylene terephthalate (PET) can be used to create insulation cores (extruded polystyrene). Styrene is the starting point for both EPS and XPS, two thermoplastic polymers with similar characteristics. Due to its greater density, XPS insulation cores are harder and more durable than EPS insulation cores. The thermal conductivity of EPS is 0.038W/mK.

The lambda value of XPS is higher than that of EPS (0.033W/mK). EPS and XPS will not burn in the presence of heat. Because of this, sandwich panels with EPS insulation cores aren’t as moisture resistant as those with XPS cores.

Mineral wool, particularly stone wool, is used as an insulating core in sandwich panels. Stone becomes malleable and can be spun into yarn when heated. Non-combustible stone wool panels are ideal for fire prevention. 

Thermal conductivity performance ranges from 0.03-0.043W/mK, making it the weakest of all core kinds. In order to get the same U value as PIR panels, stone wool panels must be nearly two times as thick as those of that material. 

Bulky, heavy panels are necessary for the construction of structurally stable mineral wool panels, which necessitate high densities (typically 100kg/m3 or more). It’s also worth noting that the open cell structure of mineral wool panels contributes to their lower thermal performance.

As well as other polymers, PUR (polyurethane) and PIR (polyisocyanurate) are frequently utilized in the insulating cores of sandwich panels (polyisocyanurate). Foams that are rigid and non-melting are incorporated in both items.

A wide range of formulas is covered by the names “PUR” and “PIR.” A full-scale fire test, such as those conducted by the insurance industry, is the only way to accurately assess PIR’s fire performance (FM & LPCB). PIR core panel performance is best evaluated through large-scale testing. In terms of heat conductivity, both PUR and PIR have values of lambda of 0.023W/mK and 0.020–0.022W/mK, respectively. 

In the event of a fire, sandwich panels with PIR insulation cores that have been certified by the insurance industry perform better. Both PUR and PIR display great moisture resistance due to their closed-cell structures.
