Explore our world-class line of vacuum insulation panels and custom structural insulated panel components.
In modern industrial and structural design, energy efficiency is no longer an optional variable but a primary regulatory requirement. Custom Structural Insulated Panel Systems (SIPs) integrated with Vacuum Insulation Panels (VIPs) represent the absolute zenith of building envelope technology. By utilizing the physics of vacuum science, we minimize heat transfer across building components, delivering thermal performance up to ten times superior to conventional glass wool or expanded polystyrene (EPS).
Thermal bridging in standard wall framing can account for up to 25% of a building's overall heat loss. By inserting vacuum insulation components inside custom structural panels, we can achieve heat transmission coefficients (U-value) as low as 0.08 W/m²·K with panel configurations that are significantly thinner than traditional solutions.
Traditional insulating materials function by trapping static air within a cellular or fibrous grid. However, air remains a thermodynamic medium that transfers kinetic energy through molecular collisions (conduction) and air currents (convection). VIPs disrupt this process. In our fumed silica-based vacuum insulation cores, the internal pressure is reduced below 1 mbar. According to the Knudsen effect, when the mean free path of gas molecules exceeds the average pore size of the core material (typically < 100 nm for fumed silica), molecular gas conduction drops asymptotically to zero.
Furthermore, infrared radiation transmission is suppressed by the incorporation of optical opacifiers within the microporous fumed silica matrix. The resulting core is sealed within an ultra-low-permeability multilayer barrier film. This high-performance gas barrier laminate prevents moisture intrusion and gas ingress, guaranteeing a stable service lifetime exceeding 50 years under standard operating conditions.

View More +The manufacturing base of Zerothermo Technology Co., Ltd. located in Nanchong City, Sichuan Province, stands as one of China's largest comprehensive centers for vacuum technology products. Under the parent umbrella of the CBVAC Group, this national high-tech enterprise integrates research, engineering, and mass-scale automated manufacturing. The factory uses fully verticalized processing systems. Raw fumed silica is compressed and structured within a dust-free cleanroom environment to guarantee consistent density and eliminate internal structural voids before vacuum packaging.
By coordinating domestic raw material logistics with advanced computer-controlled multi-chamber vacuum sealing machines, Zerothermo achieves an annual capacity exceeding hundreds of thousands of square meters. This guarantees supply security for large-scale architectural and cold-chain installations globally.
A crucial factor in VIP performance is vacuum integrity. At our Sichuan factory, every panel undergoes strict vacuum and density checks. By using helium leak mass spectrometry and thermal scanning technology, we guarantee the exact heat conductivity value before shipping. Furthermore, our ability to engineer custom shapes—including square, oval, or oversized flanges, plus micro-precision systems—allows engineers to integrate vacuum thermal barriers directly into custom structural panel designs without risking edge-seal compromise during installation.
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.
Special sizes (beyond the range of ANSI/ASME/DIN and other standards) are produced according to customers' drawings or technical parameters.
Square, oval or other special shaped flanges. Oversize/small diameter: such as diameter over 60 inches or micro precision flanges.
Special sizes (beyond standard parameters) engineered to align with extreme industrial thermal applications and vacuum envelopes.
To capture the complete thermal efficiency of vacuum insulation panels in architectural engineering, they must be integrated within structural panel matrices (SIPs) or curtain wall systems. Simply mounting VIP panels side by side will generate substantial linear heat losses along the joints—a phenomenon known as the edge-bridge effect. Zerothermo overcomes this challenge by using special polyurethane (PU) foam encapsulations and optimized overlapping profiles to construct comprehensive insulation barriers. These engineered transitions eliminate structural thermal bridging and protect the delicate vacuum core from mechanical stresses during panel handling and transport.
Combining VIP insulated wall systems with Tempered Vacuum Insulated Glass (VIG) enables designers to create high-performance building skins that achieve zero-energy target metrics. A VIG pane features a 0.1mm–0.3mm vacuum gap supported by micro-spacers, delivering thermal performance comparable to solid insulated masonry walls. This holistic strategy allows developers to maximize glazing area without compromising on carbon neutrality targets or overall energy efficiency metrics.
Delivering advanced thermal control systems through modern materials, scale manufacturing, and robust logistics networks.
Our vacuum thermal systems provide critical temperature stability and carbon emission reductions across four key sectors.
Providing high-efficiency thermal insulation solutions for building envelope systems through innovative products such as vacuum insulation panels and vacuum insulated glass, empowering the pharmaceutical cold chain sector to ensure safe logistics. These materials maintain tight temperature envelopes (+2 to +8°C, -20°C, and ultra-cold -70°C for biological vaccines) while cutting structural package thickness and reducing shipping weight.

When requesting quotes for custom Structural Insulated Panel Systems integrated with VIPs, design engineers must provide specific physical and mechanical inputs. Unlike traditional foam core panels, VIPs cannot be cut, drilled, or altered on-site, as any penetration of the outer protective skin breaks the vacuum and ruins the panel's low conductivity. Procurement managers must outline exact dimensions (length, width, thickness), edge profiles, structural support requirements, and mechanical loading limits.
Furthermore, specifying the target operating temperature range is essential. For instance, panels containing microporous fumed silica cores operate efficiently up to 900°C for industrial furnace enclosures or elevator fire doors. Conversely, cold-chain panels require PU-encapsulated vacuum cores designed for sub-zero temperatures. Clarifying these environmental profiles ensures correct material selection and precise manufacturer quoting.
Every RFQ sent to Zerothermo should include details on expected structural exposure (wind load, shear forces), target thermal performance (R-value/U-value), and necessary certifications (ISO 9001, ISO 14001, CE, ASTM class A fire ratings).
While the initial cost per square meter of fumed silica VIPs is higher than standard EPS or PIR boards, their lifetime performance delivers a lower total cost of ownership. Thinner panels save usable interior floor space in metropolitan developments, while lower HVAC power demands lead to lower operating costs. Sourcing directly from high-capacity Chinese manufacturing plants like Zerothermo's Nanchong base balances initial premium investment costs with high-yield automated production, offering competitive project pricing.
