View DetailsIn the current industrial era, reducing greenhouse gas emissions and meeting the strict global climate agreements (such as the Paris Agreement and local "dual-carbon" regulations) has made traditional insulation methods obsolete. Conventional expanded polystyrene (EPS) and polyurethane (PU) foams fail to meet modern efficiency requirements due to their thickness constraints and potential environmental impact.
As a global leader in vacuum science applications, Zerothermo Technology Co., Ltd. (a key subsidiary of the CBVAC Group) works at the intersection of material science and thermal dynamics. By using the physics of vacuum spaces, our insulation panels achieve thermal conductivity levels far below traditional limits. This level of efficiency is achieved by eliminating gas convection and reducing solid thermal pathways.
By designing fumed silica core structures with average pore diameters smaller than the mean free path of air molecules (~68nm at normal pressure), our vacuum insulation systems limit the movement of air molecules. This restricts gas-phase thermal conduction, maintaining low thermal conductivity even if vacuum levels change over time.
Industries worldwide face challenges that require next-generation insulation:
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.

Vacuum Insulation Panels (VIPs) offer significant efficiency improvements. A typical fumed silica VIP exhibits a thermal conductivity of roughly 0.004 W/(m·K) to 0.005 W/(m·K), which is up to 5-10 times lower than traditional PU foam (0.022 W/(m·K)) and EPS (0.035 W/(m·K)). This allows projects to achieve target thermal resistance values with a much thinner profile, saving cargo volume in cold chains and usable space in buildings.
Fumed silica core VIPs are engineered for long-term durability. Due to fumed silica's extremely small pore size (10-100nm), the core resists thermal degradation even if internal vacuum levels slowly decline over time. Our panels are designed to maintain excellent thermal performance for over 30 to 50 years when properly installed within protective wall systems.
Because VIPs rely on an internal vacuum state, they cannot be cut, drilled, or altered on-site, as this would puncture the high-barrier foil and cause a loss of vacuum. To support seamless installation, Zerothermo offers pre-engineered custom sizes and shapes based on technical drawings, ensuring panels fit exact project dimensions upon delivery.
Our EV battery insulation blankets are designed with thin, heat-resistant microporous materials. They are placed between battery cells to slow heat transfer during localized short circuits or thermal runaway events, helping prevent cascading fire propagation and giving occupants more time to safely exit the vehicle.
