View DetailsIn the global push for decarbonization and energy-efficient architecture, building envelope insulation has shifted from a regulatory compliance requirement to a primary design focus. Among the most vulnerable segments in any building envelope are high-aperture zones, specifically windows, spandrel panels, and glazed facades. Conventional window insulation technologies—such as double-glazed air or argon-filled units—frequently struggle to meet the strict thermal performance metrics demanded by modern regulations like the European Energy Performance of Buildings Directive (EPBD) or America's ASHRAE 90.1 standard.
“To address these thermal bridges without adding prohibitive structural weight or thickness, modern construction projects are increasingly integrating Vacuum Insulation Panels (VIPs) directly into window framings, spandrel walls, and window perimeter cavities. By lowering thermal conductivity ($\lambda$) to under 0.004 W/(m·K), VIPs provide up to ten times the thermal resistance of traditional insulation options at a fraction of the profile thickness.”
Thermal transfer across a standard barrier material occurs through three modes: solid conduction, gas conduction, and radiation. The core operating mechanism of a Vacuum Insulation Panel is the elimination of gas conduction. By creating a high vacuum inside a porous core structure and sealing it in a multi-layered gas-barrier envelope, the mean free path of any remaining air molecules becomes larger than the pore size of the core material. This phenomenon—often referred to as the Knudsen effect—effectively drops gas-based thermal conductivity to near zero.
For architectural and industrial applications, two core materials dominate the industry: Fumed Silica and Fiberglass. While fiberglass core VIPs offer high initial thermal resistance at a lower price point, they require a deep vacuum and have a shorter operational lifetime due to outgassing. Fumed silica cores, on the other hand, feature highly branched nano-porous networks that maintain excellent insulation performance even with slight pressure changes over time. This makes fumed silica the industry standard for architectural integration, where a design lifespan of 30 to 50 years is typically required.

Combining automated production and strategic logistics to deliver cost-effective vacuum insulation solutions to the global market.
A primary challenge for architectural specifiers and global buyers is sourcing window insulation panels that balance strict performance requirements with cost efficiency. Zerothermo Technology Co., Ltd., a subsidiary of the renowned CBVAC Group, addresses this challenge by combining advanced vacuum science with high-throughput manufacturing. As a recognized national high-tech enterprise, Zerothermo operates a modern production base in Nanchong City, Sichuan Province, representing one of China’s largest manufacturing facilities for vacuum technology application products.
Our Factory 4.0 facility integrates automated raw core formulation, high-precision vacuum chamber sealing, and real-time optical quality inspection. By automating the envelope-sealing process under controlled high-vacuum environments, we reduce human error, minimize edge leaks, and lower overall production costs. This combination of process automation and raw material sourcing allows Zerothermo to supply highly competitive window insulation panels to customers worldwide.
Every batch of fumed silica and fiberglass vacuum panels undergoes thermal conductivity testing via heat flow meters and pressure monitoring before leaving our facility.
We provide full design flexibility, manufacturing bespoke sizes, custom shapes (including round, 3D curved, and pass-through cutouts), and specialized edge finishes to fit specific window frames.
Leveraging the resources of the CBVAC Group, our Sichuan facility meets bulk orders for commercial developments, cold chain fleets, and appliance manufacturing lines.
The VIP industry is evolving beyond traditional square configurations toward integration into smart, multifunctional assemblies. Zerothermo's R&D team is currently focused on the following developments:
Developing silica cores blended with organic agricultural byproducts to reduce end-of-life carbon footprint while maintaining low thermal conductivity values.
Embedding ultra-thin RFID sensor tags inside the VIP envelope. This allows facility managers to check vacuum levels and structural performance via wireless scans throughout the building's life cycle.
Combining the puncture-resistant properties of aerogels with the high insulation performance of VIPs, providing a robust solution for environments prone to mechanical stress.
In addition, the integration of Vacuum Insulated Glass (VIG) with smart, dynamic electrochromic glass systems represents a major growth area. These hybrid window panels dynamically alter light transmission while maintaining high thermal performance, significantly reducing heating and cooling demands in commercial high-rises.

B2B procurement of vacuum insulation panels requires careful attention to compliance standards, import regulations, and logistics tracking. Because VIPs are sealed under high vacuum, they cannot be modified on-site. Every dimension, including cutouts and edge finishes, must be planned during the design phase. Zerothermo assists engineers and purchasing managers with detailed shop drawings and 3D modeling support prior to manufacturing.
To support global supply chains, our products comply with major international certifications:
Tested in accordance with ASTM C1667 and EN 12667 standards. Thermal conductivity values are verified using calibrated heat flow meter systems.

If a VIP is punctured, the internal vacuum is lost, and the pressure rises to atmospheric level. In this state, the panel's thermal conductivity increases to the base conductivity of its core material. For fumed silica cores, this value increases from ~0.004 W/(m·K) to ~0.020 W/(m·K), which is still comparable to conventional insulation. Because VIPs cannot be cut or drilled on-site, they must be manufactured to exact specifications, and installers must handle them carefully to avoid damage.
VIPs offer lower thermal conductivity (0.004 W/(m·K)) compared to silica aerogel blankets (typically 0.015 to 0.018 W/(m·K)). While aerogels can be cut on-site, they require greater thickness to achieve the same insulation value as VIPs. For projects with strict space constraints, VIPs provide a highly space-efficient solution.
We use multi-layer high-barrier laminate films consisting of metallized polyester (PET) layers and aluminum foils. This combination reduces gas and water vapor transmission rates. The addition of active chemical absorbent getters inside the panels captures trace moisture and outgassed molecules, preserving the vacuum for up to 50 years under standard conditions.
Yes. We design and manufacture panels with custom cutouts, complex angles, 3D curves, and circular shapes. These features are formed prior to the vacuum sealing process to ensure the vacuum integrity of the finished panel.
