The global demand for high-performance building envelopes has surged significantly, driven by stringent carbon neutrality target policies and rising utility operations expenses. As industrial infrastructure advances, the building and cold chain industries require insulation solutions that do not compromise architectural footprint sizes. Standard insulation products, such as polyurethane foam, EPS, or mineral wool, require thick cross-sectional barriers to achieve high thermal performance targets, reducing valuable internal usable space.
Advanced thermal shielding methodologies, particularly Vacuum Insulation Panels (VIPs) and Nano Microporous Insulated Panels, represent key innovations in high-efficiency thermal protection. By maintaining structural voids and utilizing high-performance core compositions like fumed silica or micro-glass fiber matrices, these products achieve thermal conductivities as low as 0.004 W/(m·K). This performance capability allows engineers to decrease composite panel thickness by up to 80% while retaining structural insulation values.
Below is a comparative breakdown of standard core structural configurations used in insulated panel technologies globally.
| Insulation Panel Type | Core Material Chemistry | Conductivity (W/m·K) | Thickness for R-30 Rating | Ideal Service Temperature |
|---|---|---|---|---|
| Fumed Silica VIP | Amorphous Fumed Silica Matrix | 0.004 - 0.006 | ~25 mm | -70°C to 120°C |
| Fiberglass Core VIP | Ultra-fine Glass Fiber Bundle | 0.002 - 0.003 (Initial) | ~15 mm | -50°C to 80°C |
| Nano Microporous Panel | Pyrogenic Silica + Opacifiers | 0.018 - 0.024 | ~100 mm | Up to 1000°C |
| Standard PIR Board | Polyisocyanurate Closed-Cell | 0.022 - 0.026 | ~150 mm | -100°C to 120°C |

Zerothermo Technology Co., Ltd., a subsidiary of the distinguished CBVAC Group, is recognized as a national high-tech enterprise. Headquartered in the Beijing Economic-Technological Development Area, our state-of-the-art production base is strategically located in Nanchong City, Sichuan Province. This facility serves as one of China’s largest production centers for vacuum technology application products.
Utilizing advanced vacuum engineering processes, we control the entire VIP fabrication lifecycle—from premium raw fumed silica preparation and core compression molding to vacuum sealing within high-barrier barrier films. This integrated process ensures consistent thermal performance across all industrial product batches.

Manufacture of square, oval, or customized micro-precision vacuum sealing flange designs up to 60+ inches to ensure high vacuum integrity.
Rigorous quality checking protocols using helium leak detection systems to guarantee long-term vacuum stability under demanding operations.
Our materials comply with rigorous testing methodologies including ASTM C1484 standard parameters, ensuring compliance for cold chain logistics and modular architectural applications in European and North American regions.
The thermal efficiency of vacuum insulation panels depends on the suppression of heat transfer mechanisms: solid conduction, gas convection, and radiation. Fumed silica cores consist of nanoporous networks with average pore diameters smaller than the mean free path of air molecules at standard pressure (around 70nm). When sealed inside a vacuum envelope, gas thermal conductivity is minimized, reducing heat transfer across the panel.
This allows fumed silica-based VIP panels to maintain low thermal conductivity levels throughout their service life. Unlike fiberglass cores, which degrade if the envelope loses vacuum pressure, fumed silica cores maintain a low thermal conductivity of approximately 0.020 W/(m·K) even if the vacuum is compromised. This provides reliable thermal safety for critical industrial applications.
Our research and development program focuses on three main engineering objectives:
Manufactured under strict ISO 9001 and ISO 14001 guidelines to ensure reliable performance in demanding environments.
