Panel thickness, core material, and surface coating can be customized to meet project requirements and align with different building standards.
High insulation, combined with a stable structure, significantly reduces the building’s long-term energy consumption and operating costs.
Stronger Load-Bearing, More Stable Roofs And Walls
The Pupael Double Skin Sandwich Panel consists of two layers of steel and a high-density core, making it stronger than ordinary single-ply panels. Roofs and walls can withstand greater loads and are less likely to buckle, even in high winds or under snow. In industrial plants, warehouses, and cold stores, this design makes the building structure more stable and reduces rework, repairs, and safety hazards caused by panel deformation. The high load-bearing capacity ensures building reliability over the long term while reducing maintenance costs.
Good Thermal Insulation And Reduced Energy Consumption
Double Skin Sandwich Panel’s high-density core provides good thermal insulation, keeping the building warm in winter and cool in summer. Compared with conventional single-skin panels or brick walls, energy consumption for air conditioning or heating can be reduced by about 15-25%. In cold rooms, warehouses, or industrial plants, this means more stable indoor temperatures and significantly lower energy bills.

- Our Factory
- Project Case
A double-skin sandwich panel consists of two layers of steel sandwiched by a high-density insulating core, making it stronger than a single-layer panel of the same thickness. It has a 25-40% higher load-bearing capacity than single-skin panels, making it suitable for use in factories and warehouses with long spans or high walls. The thickness of the middle insulation layer is uniform, which helps keep indoor temperature stable and enables the factory or cold storage to save 15-25% in energy costs year-round.
The load capacity is 0.5-1.2 kN/m² for roof panels and 1.0-2.5 kN/m² for wall panels. Typically suitable for plant, warehousing, or cold rooms with spans of 6-15 m. Pupanel will adjust panel thickness and interlayer insulation type based on the specific project requirements, ensuring the panels are factory-ready for the design loads without requiring additional reinforcement, reducing steel structure and construction costs.
The low thermal conductivity (0.022-0.028 W/m-K) of the insulation material in the middle of the sandwich panels keeps the temperature in the room stable, and Pupanel’s controlled foaming process ensures that the density of the material is uniform, so that the whole building saves 15-25% of energy throughout the year and protects the equipment and goods inside from temperature changes. Pupanel controls the foaming process to ensure uniform material density, enabling the building to save 15-25% in energy costs annually while protecting internal equipment and goods from temperature fluctuations.
The panels are made of hot-dip galvanized steel (G90 or above) with a 25-30 μm polyester coating or a PVDF high-weathering coating, which can resist salt spray corrosion for more than 1,000 hours. The seams of the panels are sealed to ensure waterproofing, structural integrity, rust resistance, and low maintenance costs. The lifespan of the panels can exceed 20 years, making them well-suited for warehouses, factories, and cold storage in coastal areas.
Thermal bridging usually occurs at the seams and corners of the panels. A Double Skin Sandwich Panel can prevent heat loss and condensation by adding flame-retardant foam or sealing strips at the seams, and by installing them in a standard manner to ensure uniform overall insulation performance.
Origin of Double Skin Sandwich Panel
The design of the Double Skin Sandwich Panel was originally inspired by the concept of “sandwich materials” in the aerospace and marine industries. The goal was to minimize material weight while maintaining structural strength. By the mid-20th century, the construction industry began adopting this design. Over the decades, the Double Skin Sandwich Panel has evolved from an engineering concept into a prefabricated enclosure commonly used in industrial buildings, warehouses, and cold chain facilities, with a complete industrialized production and installation system.
Core Advantages of Double Skin Sandwich Panel
1. Factory production and standardization
Modern Double Skin Sandwich Panel is manufactured in factories with precision, ensuring accurate panel size and thickness, and a flat surface. Standardized production not only facilitates mass production but also improves on-site installation efficiency and construction quality. There are standards in major markets around the world, such as EN 14509 in Europe and ASTM in North America, which specify requirements for panel thickness, load-bearing capacity, and fire resistance. Design and construction can reference the standards directly, reducing the likelihood of adjustments and rework.
2. Efficient structural design
Double Skin Sandwich Panel uses a typical sandwich structure consisting of top and bottom metal panels and an intermediate core material. The structural design follows the composite material principle: the metal panels are mainly subjected to bending forces, while the core material is mainly subjected to shear forces. Through this division of labor, the panels provide high stiffness and stability while remaining lightweight, making them ideal for large-span buildings.
3. Green & Sustainable
Industrialized production reduces on-site cutting and material waste. At the end of the panel’s service life, the metal portion can be fully recycled, and part of the core material can be recovered as energy. This not only reduces resource consumption but also meets the requirements of modern green buildings and sustainable development.
