High-efficiency fumed silica core insulation products providing extreme energy savings and minimal thermal transmittance across industrial & construction applications.
The global push towards carbon neutrality, net-zero energy buildings (NZEB), and high-efficiency thermal chains has propelled Vacuum Insulation Panels (VIPs) containing fumed silica core materials to the forefront of materials science. Unlike traditional polyurethane (PU) foam, expanded polystyrene (EPS), or standard mineral wools, fumed silica core VIPs deliver exceptionally low thermal conductivity—often below 0.005 W/m·K—which is up to ten times more effective than conventional insulation.
The secret behind the performance of fumed silica core vacuum insulation lies in the Knudsen Effect. Within standard insulating materials, thermal conductivity is largely determined by gas phase heat conduction—the collision of air molecules within the cellular spaces of the insulator. When the pore size of the dry silica dust core is smaller than the mean free path of gas molecules (typically < 100 nm under partial vacuum), molecular collisions with the pore walls dominate over intermolecular collisions. This virtually eliminates gaseous heat transfer.
Fumed silica (silicon dioxide, SiO₂) also possesses significant advantages over competing core materials such as glass fiber:
Maintains critical sub-zero ranges (-70°C to -20°C) for vaccine shipping containers over extended transit windows without external power requirements.
Reduces exterior wall thickness by up to 80% compared to typical EPS panels, maximizing sellable interior floor space while meeting strict LEED standards.
Provides high-efficiency thermal barriers between cells to prevent cascade failures and thermal runaway, fitting in compact vehicle footprints.
Zerothermo Technology Co., Ltd., a proud subsidiary of the distinguished CBVAC Group, is a recognized national high-tech enterprise. Headquartered within the Beijing Economic-Technological Development Area, we manage our principal industrial manufacturing base in Nanchong City, Sichuan Province. This facility ranks as one of China’s largest and most advanced integrated production complexes for vacuum technology applications.
By integrating professional research with advanced manufacturing capabilities, we support global commercial partners with robust, long-term technical solutions. Our expertise ranges from standardized vacuum insulation panels to custom, complex thermal projects, designed for longevity, high performance, and environmental compliance.
Alongside our thermal insulation profiles, our precision manufacturing division produces customized, high-vacuum mechanical flanges designed to survive strict temperature gradients:
Special sizes extending beyond regular ANSI/ASME/DIN standards, machined exactly to customer drawings or engineering parameters.
Square, oval, asymmetric, or customized profiles including oversize/micro-precision flanges reaching diameters beyond 60 inches.
Developed specifically to work hand-in-hand with low-temperature and high-vacuum experimental projects.
Why the world’s leading engineering firms choose Zerothermo as their core VIP manufacturing partner.
Our production protocols align with strict ISO 9001 and ISO 14001 standards. Each panel undergoes precise internal pressure inspection before final dispatch.

View Details +Purchasing raw core components or fully assembled VIPs from China provides structural advantages to global procurement divisions. Chinese suppliers, led by firms like Zerothermo Technology under the CBVAC Group, leverage extensive domestic raw material networks. Fumed silica, glass fiber, high-barrier laminate (HBL) film, and getter materials are sourced close to manufacturing hubs, reducing logistics costs and keeping production steady.
Furthermore, automated assembly lines and advanced robotic handling systems in Nanchong City, Sichuan Province help lower manufacturing costs. These facilities can scale production up or down rapidly to meet changing market demands, a critical factor for large-scale urban developments and seasonal refrigeration deployments.
Global procurement teams must confirm that offshore products comply with local building codes, safety regulations, and environmental standards. Leading Chinese VIP manufacturers meet these demands by maintaining active third-party certifications:
A key factor in sourcing VIPs successfully is preventing damage on site. Since vacuum insulation panels cannot be cut, drilled, or altered once sealed, precise design preparation is essential. Our team provides detailed engineering support before fabrication begins, mapping out panel positions to minimize gaps and thermal bridges. Additionally, we coordinate with local construction teams, providing handling instructions and inspection tools to ensure panels remain vacuum-sealed throughout installation.
