Standard insulating materials like polyurethane (PU) foam, expanded polystyrene (EPS), and mineral wool rely on trapping gas within pockets. However, gas conduction remains a key channel for thermal transfer. By evacuating this gas, VIPs reduce core pressure to less than 1 mbar, achieving an incredibly low thermal conductivity—typically between 0.0035 W/m·K and 0.0045 W/m·K. This is up to ten times more effective than traditional options.
Thermal transmission through any medium consists of three mechanisms: solid conduction ($\lambda_{solid}$), gas conduction ($\lambda_{gas}$), and radiative heat transfer ($\lambda_{rad}$). In a high-vacuum state, the gas conduction factor is effectively reduced to zero. This allows a very thin VIP panel (e.g., 15mm) to match the thermal resistance of a 120mm traditional PU board. This reduction in thickness translates directly into space savings, increased payload capacities in cold chain operations, and higher rentable square footage in urban developments.
When procurement teams evaluate VIP panel quotes, it is vital to look beyond the initial cost per square meter. Pricing is determined by several technical factors that directly impact long-term reliability:
| Technical Parameter | Fumed Silica Core VIP | Fiberglass Core VIP | Impact on Pricing & Lifespan |
|---|---|---|---|
| Initial Thermal Conductivity | 0.004 - 0.005 W/m·K | 0.0015 - 0.0025 W/m·K | Fiberglass has a lower initial value, but degrades rapidly without a perfect vacuum. |
| Lifespan Expectation | Up to 50 Years | 5 to 15 Years | Fumed silica maintains low thermal conductivity even if vacuum pressures rise slightly. |
| Pressure Tolerance | Maintains performance up to 100 mbar | Requires pressure below 1 mbar | Fumed silica has smaller pore sizes (<50nm), reducing the risk of vacuum failure. |
| Flammability Class | Class A (Non-combustible core) | Class A (Non-combustible) | Fumed silica core is naturally fireproof, ideal for construction and EV applications. |
| Relative Unit Cost | Higher (Premium Core Material) | Lower (Utility Grade) | Fumed silica offers a much higher return on investment over its lifetime. |
We are replacing classic metallized laminate foils with ultra-thin, non-metallic multi-layer barrier films. This helps prevent edge thermal bridging, ensuring consistent performance across the panel surface.
By blending fumed silica core structures with nano-aerogels, we have developed a hybrid panel that improves mechanical flexural strength without sacrificing thermal resistance.
Integrating RFID and NFC sensor tags directly inside the panel envelope allows logistics managers and building inspectors to check vacuum levels instantly using handheld scanners.
We are working on bio-based carbon silica core formulations. This will lower the carbon footprint of production, aligning our panels with international net-zero building standards.
Vacuum Insulation Panels are no longer limited to high-end laboratory appliances. Today, they serve as critical infrastructure components across several key industries:
Ensures safe transit for temperature-sensitive biologics, vaccines, and cell therapies. Operating in combination with phase change materials (PCMs), our VIP panels maintain steady temperatures between -70°C and 8°C for over 120 hours without external power.
Designed for space-constrained city retrofits, curtain walls, and terraces. Our panels deliver high insulation ratings with minimal thickness, helping projects meet passive house design standards.
Provides critical thermal protection inside EV battery packs. Our thin VIP blankets act as fire-resistant barriers, preventing thermal runaway between battery cells while preserving cabin space.
Saves energy in high-heat settings like water heater jackets, industrial piping systems, and laboratory furnace linings.
Zerothermo Technology Co., Ltd., a subsidiary of CBVAC Group and a national high-tech enterprise, is headquartered in the Beijing Economic-Technological Development Area with its production base located in Nanchong City, Sichuan Province. This facility stands as one of China’s largest comprehensive production centers for vacuum technology application products.

Special sizes (beyond the range of ANSI/ASME/DIN and other standards) are produced according to customers' drawings or technical parameters.
As a national high-tech enterprise backed by the CBVAC Group, Zerothermo Technology operates under a Factory 4.0 manufacturing framework. This integration combines precision vacuum engineering with advanced automated assembly lines. Our production facility in Nanchong, Sichuan Province, features state-of-the-art automation designed to keep thermal barrier qualities consistent while reducing structural costs.
Vacuum failure is often caused by moisture outgassing from the core material over time. To prevent this, our production base uses high-temperature vacuum drying ovens. These units dry the fumed silica cores to a moisture content of less than 0.1% before sealing. The cores are then automatically cut using CNC profiling saws, ensuring clean dimensions for custom projects.
Every single VIP panel we produce undergoes a strict non-destructive quality check. We test the inner gas pressure using our proprietary laser-optical vacuum scanners. Any panel that shows a pressure rise of more than 0.5 mbar during standard aging tests is rejected. This rigorous quality control ensures that our fumed silica VIP panels deliver a reliable, long-term service life of up to 50 years.
Global procurement teams must balance logistics costs with supply chain reliability. By keeping core processing, barrier lamination, and quality testing in-house, Zerothermo eliminates the need for third-party subcontractors. This vertical integration allows us to offer stable pricing and shorter lead times, making us a dependable partner for large-scale construction projects and high-volume cold chain container manufacturing.
