Learn MoreTraditional insulation products like polyurethane foam, mineral wool, and expanded polystyrene rely on trapping gases within their cell structures to limit heat conduction. However, gas conduction remains a substantial channel for thermal transfer. Vacuum Insulation Panels (VIPs) eliminate this thermal bypass by evacuating gas molecules down to pressures of 1 mbar or lower, achieving thermal conductivity rates between 0.0015 W/mK and 0.004 W/mK. This is up to ten times more efficient than traditional materials.
At the heart of the VIP is the core material, which prevents atmospheric pressure from collapsing the panel. Our core technology leverages fumed silica, a nanostructured porous matrix characterized by pore diameters smaller than the mean free path of air molecules at atmospheric pressure (often referred to as the Knudsen effect). This physical principle ensures that even if minor vacuum degradation occurs over decades, the gas conduction remains low.
The global market for vacuum insulation panels is expanding rapidly, driven by stringent energy efficiency directives (such as the EU Ecodesign Directive, US DOE regulations, and China's Dual-Carbon policy targets). In the domestic refrigeration space, refrigerator and freezer manufacturers face pressure to achieve "Class A" energy labels while maximizing internal volume.
By implementing VIP for Freezer Insulation, manufacturers can reduce insulation wall thickness by up to 60%, expanding internal storage capacity by 20% to 30% without changing the outer dimensions. Similar space-saving demands exist in ultra-low temperature (ULT) lab freezers, LNG maritime transport, and cold chain shipping containers. This balance between volume maximization and thermal efficiency has shifted VIPs from a niche solution to a global standard.

View DetailsZerothermo Technology Co., Ltd., a subsidiary of the CBVAC Group, is a national high-tech enterprise. Headquartered in the Beijing Economic-Technological Development Area, our production base is located in Nanchong City, Sichuan Province. This facility stands as one of China’s largest and most comprehensive production centers for vacuum technology application products.
By leveraging CBVAC Group's extensive vacuum systems expertise, we manufacture high-performance vacuum insulation panels, vacuum insulated glass, and tailored microporous thermal products. Our vertical integration, from raw silica formulation to advanced vacuum sealing, ensures consistent quality that complies with global energy standards.
Strategic deployment parameters addressing diverse climate zones, global supply chains, and evolving environmental regulations.
Thermal demands vary by territory. In the European Union, regulations favor low-carbon building envelopes and Class A home appliances. In this market, VIPs are integrated directly into exterior wall systems (EIFS) and ultra-slim domestic refrigerators to maximize space in compact urban apartments.
In North America, the focus is on heavy industrial cold storage, vaccine distribution networks, and logistics. Our fumed silica VIPs provide stable thermal barriers for container shipments crossing multiple climate zones.
In Asia, humid tropical environments present challenge for barrier degradation. Zerothermo uses multi-layer co-polymer films with specialized getter elements to capture internal moisture and gas molecules, maintaining low pressure inside the panel.
Zerothermo Technology focuses on three primary R&D targets for next-generation vacuum insulation panels:
Leveraging deep industrial expertise, modern production bases, and CBVAC Group’s extensive vacuum engineering history.
Manufactured under strict ISO-9001 and ISO-14001 certifications. Each panel undergoes helium leak detection and thermal scans before shipment.

Under typical conditions in domestic refrigerators or building walls, fumed silica VIPs are designed to last between 30 and 50 years. Fumed silica has a nano-porous structure that helps maintain low thermal conductivity even if internal pressure increases over time (e.g., from 1 mbar up to 100 mbar). This pressure resistance gives fumed silica cores a longer service life than fiberglass cores, which degrade quickly with minor vacuum loss.
Because the protective outer barrier film contains thin metallic foil or metalized layers, heat can transfer more quickly along the edges of the panel than through its center. To address this edge effect, our design team recommends using multi-layer staggered joint configurations, wrapping panels in polyurethane foam outer protective casings, or using metal-free polymeric barrier films for applications that require high thermal efficiency.
No, standard vacuum insulation panels cannot be cut, drilled, or machined after fabrication. Modifying the panel punctures the outer barrier envelope, instantly venting the vacuum to atmospheric pressure and reducing thermal performance to that of conventional core silica. All penetrations, cutouts, and dimensions must be designed beforehand and custom-built during our manufacturing process.
Fumed Silica VIPs feature an average pore diameter of roughly 10–20 nanometers, requiring less vacuum depth (down to 1–10 mbar) to achieve optimum performance. They resist moisture aging and maintain a long operating life. Fiberglass VIPs have larger micro-scale pores and require a deep vacuum (0.01 mbar). This makes them susceptible to thermal degradation if moisture or gas enters the panel, though they typically offer lower initial production costs.
Moisture ingress can slowly degrade performance by increasing gas conduction within the panel. To protect against moisture, Zerothermo panels use advanced multi-layer barrier films, desiccant materials, and active getter packs. These components absorb water vapor and atmospheric gases, extending the panel's thermal performance in warm and humid conditions.
