Material Properties of Cold Room Panels
Cold room panels are vital insulation materials for food preservation and various industrial applications. The material properties of these panels may vary depending on usage areas and needs.
What are Cold Room Panels?
Cold room panels are sandwich panels sandwiched between metal sheets, usually filled with insulation materials such as polystyrene or polyurethane. These panels help maintain low temperatures thanks to their high insulation properties.
Panel surface materials
The outer surfaces of cold room panels are usually made of galvanized steel, stainless steel or aluminum. These materials increase the durability of the panels and provide protection against corrosion.
Galvanized steel: Galvanized steel has high corrosion resistance thanks to the zinc coating. This ensures the longevity of the panels and reduces the need for maintenance.
Stainless steel: Stainless steel is known for its high strength and corrosion resistance. Additionally, it is widely used in the food industry thanks to its hygienic surface.
Aluminum: Aluminum stands out with its lightness and corrosion resistance. Additionally, because it is easily shaped, it can be made suitable for various applications.
insulation materials
The insulation materials used inside the cold room panels determine the insulation performance of the panel. The most commonly used insulation materials are:
Polyurethane: Polyurethane foam is known for its high insulation value and low thermal conductivity. This material is frequently used inside cold room panels and provides an excellent thermal barrier.
Polystyrene: Polystyrene is a cost-effective and effective insulation material. It is generally used in the form of polystyrene sheets or foams and offers good thermal performance.
Phenolic Foam: Phenolic foam stands out with its low thermal conductivity and high fire resistance. Thanks to these features, it is especially preferred in applications where fire safety is important.
Panel Thickness and Density
The thickness and density of cold room panels affect their insulation performance and mechanical strength. The thickness of the panels usually varies between 50 mm and 200 mm. Thick panels offer higher insulation performance, while thin panels provide more flexible application.
Thickness: The thickness of the panels directly affects the insulation performance. Thicker panels provide better insulation and help maintain cooler temperatures.
Intensity: The density of the panels determines the mechanical strength and insulation performance. High-density panels offer better insulation and durability, but are also heavier.
Performance Features of Cold Room Panels
Cold room panels must have certain performance characteristics. These features affect the lifespan and efficiency of the panels.
Thermal conductivity and insulation value
The main function of cold room panels is to maintain low temperatures. Therefore, the thermal conductivity of the panels must be low and offer high insulation value.
Thermal conductivity: Thermal conductivity indicates how well a material conducts heat. Materials with low thermal conductivity provide better insulation.
Insulation value: Insulation value shows how well a material prevents heat loss. High insulation value means better energy efficiency and lower operating costs.
fire resistance
The fire resistance of cold room panels is a safety-critical feature. Panels produced using fire-resistant materials increase safety and reduce damage in case of fire.
Fire class: The fire class of cold room panels indicates the fire resistance of the panels. Fire-resistant panels generally have class A fire resistance.
Fire insulation: Panels produced using fire-resistant insulation materials prevent the spread of heat in case of fire and preserve structural integrity.
Moisture resistance and vapor barrier
Cold room panels must prevent moisture and vapor from passing through the panel. This feature increases the insulation performance and life of the panels.
Non-resistance: The moisture resistance of the panels prevents moisture from penetrating into the panel. This helps maintain the insulating properties of the panel.
Vapor barrier: The vapor barrier prevents vapor formation and condensation inside the panel. This feature is especially important in food preservation.
Mechanical strength and strength
Cold room panels must be resistant to external influences. The mechanical strength of the panels ensures that they maintain their structural integrity.
Compressive strength: The compressive strength of the panels determines their resistance to external forces. Panels with high pressure resistance are more durable and reliable.
Resistance to impacts: It increases the impact resistance of the panels and their resistance to external influences. This feature is especially important in logistics and transportation processes.
