Global Industrial Whitepaper
In an era structured around strict decarbonization goals, energy efficiency has moved from a compliance check box to a vital competitive parameter. The thermal insulation market is witnessing a major shift, migrating away from conventional porous materials toward ultra-high-efficiency Vacuum Insulation Panels (VIPs) and nano-microporous structures. Traditional insulation systems—such as polyurethane (PU) foam, expanded polystyrene (EPS), and mineral wool—rely on trapping gas inside pockets. However, the thermal conductivity of the static gas still sets a limit on their insulating capability.
VIPs overcome this thermodynamic limit by removing gas molecules from the core structure altogether. This reduces gas conduction and convection to near zero. By maintaining internal vacuum pressures below 1 mbar, VIPs achieve design thermal conductivities ($\lambda$-values) as low as 0.002 to 0.004 W/(m·K). This level of performance is roughly 5 to 10 times more effective than conventional options, enabling thinner insulation envelopes, increased storage volumes, and superior thermal retention.
| Insulation Type | Core Density (kg/m³) | Thermal Conductivity (W/m·K) | Thickness Req. for R-10 (mm) | Lifespan / Reliability |
|---|---|---|---|---|
| Fumed Silica VIP | 180 - 220 | 0.004 (at vacuum) | 20 mm | Up to 50 Years (Low aging rate) |
| Fiberglass Core VIP | 240 - 280 | 0.002 (at vacuum) | 10 mm | 10 - 15 Years (Higher moisture sensitivity) |
| PU Foam | 35 - 45 | 0.023 - 0.028 | 120 mm | Gradual aging due to cell gas escape |
| Mineral Wool | 80 - 140 | 0.035 - 0.040 | 180 mm | Moisture-dependent breakdown |
Enterprise procurement teams must understand the core structural difference when ordering custom VIP panels. Fumed silica core panels feature a matrix of nano-sized amorphous silica particles. This matrix creates a microporous network with average pore diameters smaller than the mean free path of air molecules at atmospheric pressure (~70 nm). As a result, fumed silica VIPs maintain excellent insulation properties even if the vacuum degrades over time. Conversely, fiberglass core VIPs achieve lower initial thermal conductivity values (~0.0018 W/(m·K)) but are more sensitive to vacuum loss, requiring high-grade envelope protection and dessicant systems to prevent performance drops.
Moving vacuum insulation panels globally requires specialized handling and manufacturing processes. Because VIPs are pre-fabricated to exact dimensions and cannot be modified or cut on-site, modern manufacturers need to integrate custom designs early in the engineering phase. Standard shipping methods can expose VIPs to pressure changes, puncture risks, and high humidity. High-quality VIP manufacturers use multi-layered aluminum barrier films with advanced sealing designs to withstand transit stresses, ensuring panels arrive with their vacuum intact.
Manufacturing Powerhouse
Zerothermo Technology Co., Ltd., a subsidiary of the renowned CBVAC Group, is a national high-tech enterprise at the forefront of vacuum technology applications. Headquartered in the Beijing Economic-Technological Development Area, the company operates its advanced production base in Nanchong City, Sichuan Province. This specialized facility represents one of China's largest comprehensive production centers for vacuum insulation products and high-vacuum equipment.
