Engineered for Germany's stringent commercial energy efficiency benchmarks, featuring advanced core technology and optimized joint profiles.
The German industrial construction market operates under some of the world's most rigorous energy conservation rules. The Building Energy Act (Gebäudeenergiegesetz - GEG) sets tight parameters for the thermal performance of building envelopes. To meet these targets, developers, architects, and structural designers must specify thermal building materials that deliver low U-values alongside exceptional mechanical stability.
Our polyurethane (PU) and polyisocyanurate (PIR) core sandwich panels are engineered specifically to exceed these requirements. With thermal conductivity (lambda value λ) down to 0.022 W/m·K, our panel configurations enable thin envelope constructions while yielding passive-house levels of heat retention. This translates directly to minimized operational carbon footprints and compliance with modern DGNB or KfW green building incentives.
| Panel Core Type | Nominal Thickness | U-Value (W/m²·K) | GEG Compliance Status |
|---|---|---|---|
| High-Density PIR | 50 mm | 0.44 | Suitable for internal zones |
| High-Density PIR | 100 mm | 0.22 | Standard Industrial Roof/Wall |
| Advanced PIR Core | 120 mm | 0.18 | High Energy-Saving Projects |
| Premium PU/PIR | 150 mm | 0.14 | Low-Energy & cold storage |
| Super-Insulated PIR | 200 mm | 0.11 | Passive Warehouse / Deep Freeze |
Providing engineered surfaces that deliver structural integrity, superior aesthetics, and compliance with European safety criteria.
Our sandwich panel lines integrate robust technical parameters to fulfill complex structural demands, ensuring maximum resilience and lifecycle performance.
Compliance with European standard EN 13501-1 demands rigorous flame retardancy. Our PIR cores use optimized chemical cross-linking that yields a carbonaceous protective layer under fire conditions, slowing thermal progression and limiting smoke emissions to satisfy B-s1,d0 requirements.
Utilizing high-tensile steel skins (0.5mm to 0.7mm) and a high-density polyisocyanurate core, our sandwich panels provide great bending resistance. This allows for wider purlin spacing in industrial construction, reducing support structure weight and overall project costs.
For chemical manufacturing sites, maritime storage hubs, or food processing environments in Germany, panels require targeted surface protection. We offer galvanized steel skins with PVDF, Plastisol, or PUR-PA coatings designed for C3 to C5-I/M corrosion categories.
Procuring building envelopes directly from a specialized Chinese manufacturer yields significant cost advantages, provided the supplier has a robust quality control and logistics framework in place. Ningbo Jonas Build Co., Ltd. bridges the gap between cost efficiency and European quality standards.
We coordinate end-to-end logistics from our modern plant near China’s premier container ports directly to key German cargo hubs, such as Hamburg, Bremerhaven, Duisburg, or Wilhelmshaven. By optimizing container loads with custom packaging (including heavy-duty protective PE films, EPS side blocks, and moisture-controlled sea-wrap packaging), we ensure that your cladding panels arrive scratch-free and ready for installation.
Our engineering team coordinates with your site managers to schedule deliveries in alignment with your assembly timeline, minimizing storage fees and double-handling on site.
Get Technical Project ConsultingAs the European market tightens environmental and circular economy legislation, our technical design roadmap is focused on three primary areas.
We are actively registering Environmental Product Declarations (EPDs) for our product lines. EPDs document the life-cycle environmental impact of our panels, enabling developers to achieve higher points in BREEAM, LEED, and DGNB rating systems.
Our sandwich design simplifies the mechanical separation of steel skins from the rigid polyurethane core at the building's end-of-life, supporting circular recycling paths for both raw materials.
Continuous research and development focuses on halogen-free flame retardants and increasing bio-based raw material ratios within the polyol component, reducing reliance on fossil resources.

Common inquiries from German building developers, structural engineers, and procurement specialists.
Yes. Our panels are designed to meet the U-value and air-tightness parameters defined by the German Building Energy Act (GEG). We offer custom thickness options (up to 200 mm) to achieve the low thermal transmittance required for modern building envelopes.
Our PIR core panels are tested in accordance with EN 13501-1, typically achieving fire ratings of Class B-s1,d0 or B-s2,d0. This indicates low flame spread, minimal smoke generation, and no flaming droplets/particles during testing.
We offer hot-dip galvanized steel skins (Z275/AZ150) coated with high-performance systems like PVDF, Plastisol, or PUR-PA (Polyurethane-Polyamide). These are designed to withstand harsh industrial or coastal environments, matching classes from C3 up to C5-I/M.
Production timelines generally range between 15 to 25 days, depending on order size and customization requirements. Ocean freight from our plant near Ningbo port to German terminals like Hamburg or Bremerhaven takes approximately 30 to 35 days.
Yes, we can match any standard RAL color code for the exterior steel skins. We also offer standard finishes like RAL 9002 (Grey White), RAL 9006 (White Aluminium), and RAL 7016 (Anthracite Grey) to suit local architectural styles.
Panels are bundled with protective PE film, stacked with EPS spacing blocks, and wrapped in heavy-duty waterproof film. The bundles are secured on robust timber pallets and loaded into shipping containers using specialized textile strapping to prevent movement during transit.
To optimize container utilization and ensure cost-effective shipping rates, our standard MOQ is 500 square meters. However, we can accommodate smaller quantities for mock-ups or pilot projects in coordination with existing production runs.
