Premium fumed silica vacuum insulation panels, VIPs, and high-temperature microporous materials directly from China's leading factory.
The global demand for high-performance sound insulation boards and advanced thermal barriers has experienced an unprecedented surge. In an era shaped by stringent net-zero goals and demanding acoustic design parameters, Zerothermo Technology Co., Ltd. (a key subsidiary of the CBVAC Group) stands as a beacon of engineering excellence. Operating out of our state-of-the-art production base in Nanchong City, Sichuan Province, we operate one of China's largest and most technologically integrated manufacturing facilities for vacuum applications.
By executing "Industry 4.0" automation methodologies, our production lines achieve uncompromised material homogeneity. Through continuous monitoring, automated vacuum sealing, and high-frequency acoustic core density verification, we guarantee that every sound insulation board and thermal vacuum insulation panel (VIP) conforms to the tightest engineering tolerances. Our vertically integrated supply chain—spanning raw fumed silica formulation to sophisticated multi-layer barrier film laminations—mitigates systemic supply chain disruptions, allowing us to supply large-scale global infrastructure projects with shorter lead times and optimal pricing matrices.
Our sound insulation and vacuum panels utilize nanostructured cores that bypass classic acoustic transmission pathways. By combining high-density fumed silica with specialized structural binders, we achieve extremely low thermal conductivity values (≤0.002 W/m·K) alongside high decibel-reduction coefficients (STC up to 55dB), making them ideal for space-constrained urban construction and precision high-temperature applications.
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.
We leverage advanced physics and material sciences to tackle complex thermal bridging and acoustic leaks. With custom flanges, shaped vacuum profiles, and specialized structural barriers, we bridge the gap between heavy industrial engineering and highly aesthetic architectural configurations.
Special sizes (beyond the range of ANSI/ASME/DIN and other standards) are produced according to customers' drawings or technical parameters.
Square, oval, or custom-shaped geometries. Oversize/small diameter configurations such as diameters exceeding 60 inches or micro-precision structural flanges.
All non-standard components undergo strict pressure and helium leak testing to guarantee stability for high-consequence thermal and acoustic environments.
A deep look into the structural physics and material breakthroughs driving next-generation thermal-acoustic barriers.
Traditional acoustic and thermal materials rely on mass and thickness to restrict sound or heat. Our roadmap focuses on vacuum-sealed micro-cavity structures. By evacuating gas molecules down to less than 1 mbar within a fumed silica matrix, the mean free path of any remaining air molecules exceeds the pore size of the core material. Conduction and convection are virtually eliminated, while acoustic waves dissipate through destructive interference in the micro-porous structure.
The lifespan of a Vacuum Insulation Panel (VIP) depends directly on the integrity of its barrier envelope. Zerothermo's current R&D focuses on multi-layer hybrid films utilizing atomic layer deposition (ALD) of metal oxides. These films reduce gas transmission rates (GTR) to near zero, maintaining insulation values for over 50 years. This satisfies the strict life-expectancy standards required in modern building designs and industrial systems.
Future development is shifting toward fully recyclable core materials. By using bio-sourced silica and carbon-neutral binding polymers, our new research line aims to produce structural insulation boards with a lower carbon footprint while maintaining class-leading R-values and STC parameters.

Providing high-efficiency thermal insulation solutions for building envelope systems through innovative products such as vacuum insulation panels and vacuum insulated glass, empowering the construction sector to reduce carbon emissions and achieve carbon neutrality.
Delivering nano-microporous thermal barriers that withstand temperatures up to 1000°C. These insulation systems are optimized for industrial kilns, smelting furnaces, and backup insulation in metallurgical applications to ensure safe operation and lower energy costs.
Offering specialized acoustic panels and light thermal barriers for modular architectural designs, prefab cabins, and eco-resort builds, combining low physical profiles with excellent noise insulation.
1. Core Material Density: Ensure fumed silica core density falls between 160-220 kg/m³ for the best balance of insulation performance and structural stability.
2. Internal Pressure Tolerances: Specify internal pressure limits of ≤ 5 mbar to maintain target thermal performance over the long term.
3. Thermal Bridging Margins: Account for edge effects in high-density grid layouts using multi-layered staggered installation configurations.
Our sound insulation boards utilize high-damping polymeric layers and dense core matrices. They achieve high sound transmission class (STC) ratings with thinner profiles than traditional drywall or fiberglass systems, helping to save valuable indoor space.
Procuring advanced insulation materials requires close attention to international shipping logistics, moisture-proof packaging, and custom clearance paperwork. Zerothermo Technology provides end-to-end container support to protect materials from handling damage during sea transit.
Our customer service team coordinates closely with freight partners to streamline deliveries across North America, Europe, and the Asia-Pacific region. Every shipment includes clear QC documentation, vacuum retention tests, and batch traceability certificates to simplify import compliance and project auditing.
To help clients optimize their budgets, we provide scaled pricing based on total square footage, delivery timelines, and panel design configurations. Whether supplying custom VIP panels for new energy vehicle production runs or modular building assemblies, we provide tailored quotes that balance unit costs with logistics efficiency.
Building designs must comply with regional energy efficiency codes like the EU Energy Performance of Buildings Directive (EPBD) or ASHRAE standards in North America. Zerothermo VIPs are designed to help you meet these goals by providing high thermal performance in thin, space-saving profiles.
Our production base follows strict ISO 9001 and ISO 14001 guidelines to ensure consistent quality and environmental management. Our materials undergo rigorous ASTM testing for thermal resistance, fire safety (non-combustibility standards), and long-term aging characteristics.
We supply complete material safety data sheets (MSDS), environmental product declarations (EPD), and RoHS compliance test reports. This comprehensive documentation helps developers and engineers secure project approvals and green building certifications, such as LEED or BREEAM.

With high-barrier multi-layer films and built-in getters to capture moisture and gas, Zerothermo VIPs are designed to maintain their high thermal performance for 30 to 50 years under standard building conditions.
No. Vacuum Insulation Panels must not be cut, drilled, or altered, as this releases the internal vacuum and reduces their insulation performance. We provide customized dimensions based on your architectural drawings to ensure panels fit without modifications.
Our silica cores are made of non-combustible materials. Depending on the outer barrier film and any protective coverings, our panels can be integrated into wall and door assemblies that meet international non-combustible fire regulations.
Minimum Order Quantities depend on the level of customization required for panel sizes. Lead times typically range from 2 to 4 weeks from drawing sign-off to shipment from our factory in Nanchong City.
