There are many specifications of sandwich panels available in the market, and the thickness of the sandwich panels is closely related to their usage.
A sandwich panel is a composite panel made of two layers of metal sheets with a core material in between. The thickness of such panels typically ranges from 20 mm to 200 mm. Due to their excellent performance, these panels are widely used. Depending on different applications, people choose sandwich panels of different thicknesses.
50 mm Thick Sandwich Panels
Many fireproof partitions or temporary buildings use this type of sandwich panel. This is because it provides basic insulation, soundproofing, and fireproof functions. More importantly, it is lightweight and inexpensive, making it ideal for small or temporary structures.
75 mm Thick Sandwich Panels
Sandwich panels of this thickness have some thermal insulation capability. Although insufficient for applications such as cold storage, they can maintain indoor temperature stability well. Therefore, many warehouses use panels of this thickness.
100 mm Thick Sandwich Panels
Locations such as industrial plants that require strong thermal insulation often use panels of this thickness. In addition to providing insulation, these panels also offer significant structural strength, making them suitable for buildings like factories where walls or roofs need to bear some load.
Additionally, many medium- and high-temperature cold storage facilities also use sandwich panels of this thickness.
150 mm Thick Sandwich Panels
Panels thicker than 120 mm are generally used for low-temperature cold storage. These cold storage facilities require high insulation performance due to their low temperatures. Sandwich panels of 120 or 150 mm thickness can effectively maintain the temperature of stored items, protecting them from external influences.
200 mm Thick Sandwich Panels
Panels of this thickness are mainly used in ultra-low temperature cold storage or heavy-duty industrial buildings. The 200 mm thick panels provide excellent thermal insulation, maximizing the efficiency of refrigeration equipment and ensuring the low temperature of stored items. Additionally, due to their large thickness, these panels have strong structural strength and can support heavier loads.
