High-performance vacuum technology products and nanostructured materials customized for complex thermal management challenges.
In the modern era of industrial engineering, building construction, and high-precision temperature control systems, energy efficiency is no longer merely a design option—it is a regulatory and functional imperative. High-performance insulation materials represent the frontline defense against thermal loss, carbon emissions, and operational inefficiency. The global market is rapidly transitioning from legacy bulk insulators (such as mineral wool, expanded polystyrene [EPS], and polyurethane foam) toward advanced nanotechnology-driven solutions, including Fumed Silica Vacuum Insulation Panels (VIPs) and Nano-Microporous systems.
This transition is driven by stringent carbon neutrality policies worldwide, such as the European Green Deal and China's "Dual-Carbon" (Peak Carbon & Carbon Neutrality) initiatives. Traditional insulation materials are limited by the physical constraints of conduction, convection, and radiation. For instance, conventional polyurethane has a thermal conductivity (K-value) limit of approximately 0.022 W/m·K. To achieve the high-efficiency requirements of Net-Zero Energy Buildings (NZEB) or complex industrial furnace containment, traditional insulators require impractical wall thicknesses. Vacuum Insulation Panels (VIPs), by contrast, exploit the lack of air molecules in a vacuum space to dramatically reduce gas conduction, achieving K-values as low as 0.004 W/m·K—effectively yielding five times the thermal resistance at a fraction of the thickness.
The superior efficiency of Zerothermo's fumed silica cores lies in the Knudsen effect. By structuring the core matrix with pore diameters smaller than the mean free path of air molecules (approx. 70 nanometers at standard pressure), free molecular movement is obstructed, virtually eliminating gas-phase heat transfer even if microscopic quantities of air slowly ingress over decades of operational life.
As a global epicentre for manufacturing scale and raw material processing, China offers unparalleled benefits to international procurers of insulation materials. Strategic integration of supply chains—specifically for key components like high-purity fumed silica, high-barrier laminates, and advanced getters—allows Chinese factories to achieve unmatched cost-to-performance ratios.
Furthermore, manufacturing efficiency in China is driven by capital investment in specialized automated production lines. Industrial automation guarantees precise control over vacuum levels, edge-sealing integrity, and dimensions. Zerothermo Technology Co., Ltd. leads this manufacturing revolution by combining the extensive vacuum equipment expertise of our parent enterprise, CBVAC Group, with advanced robotic processing. This setup eliminates human error during critical sealing and evacuation stages, ensuring that every panel leaving the factory maintains long-term reliability and compliance with ASTM and ISO international standards.

The physical environment dictate the chemical and structural configurations of vacuum insulation. Standard VIPs cannot simply be deployed in high-temperature zones or sub-zero cryo-chambers without custom engineering. High-performance insulation requires precise adaptation to localized application scenarios:
When purchasing heat insulation panels at an industrial scale, buyers must evaluate the Total Cost of Ownership (TCO) beyond the base product pricelist. Low-quality options often suffer from premature vacuum failure caused by poor laminate moisture-barrier layers or inadequate getters. Key technical specifications to request during RFQs include:
Crucial technical answers regarding the deployment, specifications, and lifespan of vacuum insulation systems.
Fumed silica core VIPs feature a nanoporous structure with typical pore sizes of 10-20nm. This prevents convection and gas-phase conduction, maintaining a thermal conductivity of ≤ 0.005 W/m·K even if internal pressure rises over time. In contrast, fiberglass core VIPs offer high initial thermal efficiency but degrade quickly if the barrier film is punctured or suffers moisture ingress. Fumed silica also provides superior fire safety performance, meeting Class A non-combustible building codes.
No, VIPs cannot be modified on-site. The panel's performance depends on maintaining a hermetically sealed vacuum chamber within the barrier envelope. Any puncture, trimming, or drilling will immediately equalize the internal pressure with the atmosphere, degrading the K-value from 0.004 W/m·K to approximately 0.020 W/m·K. Architectural and industrial projects require pre-planned custom dimensions, combined with legacy board filler strips to accommodate edge variances.
Our fumed silica VIPs are designed for a service life exceeding 50 years under standard building conditions (EN 12667). By integrating high-performance multilayer aluminum laminate barrier films and specialized chemical getters to capture moisture and gas molecules, we restrict the internal pressure rise to less than 1.5 mbar per year, preserving high insulation performance over the long term.
Unlike standard VIPs, high-temperature nano microporous boards are engineered to operate in environments from 650°C up to 1050°C. These find application in fire doors, industrial kilns, and metallurgical components. The board matrix remains stable under extreme temperatures, preventing thermal collapse and maintaining a low K-value of 0.020 to 0.035 W/m·K at high operational limits.
