Vacuum Insulated Panels (VIPs) represent the absolute zenith of modern insulation technology. By utilizing a evacuated porous core material encapsulated within a gas-tight high-barrier envelope, VIPs achieve a thermal conductivity rating (λ-value) typically below 0.004 W/(m·K). This performance is up to ten times superior to traditional insulation media such as expanded polystyrene (EPS) or polyurethane (PU) foam. As industries pivot toward net-zero targets and extreme space optimization, sourcing VIPs from reliable factories has transitioned from a specialized design choice to a core strategic procurement mandate.
While the search for "cheap" VIP vacuum insulated panels is common, procurement directors must evaluate the Total Cost of Ownership (TCO). A lower initial capital expenditure (CAPEX) must align with long-term barrier integrity. Substandard barrier foils or poorly processed core materials can lead to premature vacuum decay, degrading the panel's performance back to that of standard silica. Leading OEM manufacturers resolve this by integrating automated envelope wrapping and in-line quality diagnostics.
The global VIP industry has matured across three key pillars:
Industrial demand patterns reveal distinct geographic and application requirements:
By leveraging CBVAC Group's deep heritage in vacuum chamber technology, our Nanchong production facility utilizes fully automated core compression, envelope pocketing, and vacuum sealing lines, reducing human error margins to near zero.
Every single VIP produced undergoes non-destructive pressure testing and thermal imaging. This ensures that only panels with internal pressures below 5 mbar leave our shipping docks.
Located in Sichuan Province, our production base benefits from efficient raw material sourcing and competitive utility costs, passing significant value back to global procurement teams.

View Details +Zerothermo Technology Co., Ltd., a subsidiary of the distinguished CBVAC Group, is a leading high-tech enterprise. Headquartered within the Beijing Economic-Technological Development Area, our primary production center spans a massive facility in Nanchong City, Sichuan Province. This base stands as one of China’s largest and most comprehensive production centers for vacuum technology application products.
Engineered to custom specifications exceeding ANSI/ASME/DIN standards based on drawings or client parameters.
Square, oval, and specialty configurations. Large diameter capacities scaling over 60 inches down to micro-precision sizes.
Proprietary alloys and heat-treated flanges designed to interface with advanced vacuum chambers.
Ensuring vaccine shipment integrity with advanced core packaging that maintains ultra-cold levels for extended transit times.
Ultra-thin insulating walls enabling zero-carbon green buildings to maximize internal square footage without sacrificing compliance.
Nano-microporous shields and thermal barriers safeguarding elevators, fire protection doors, and refinery machinery.
Integrating thermal structural elements in prefabricated modular homes and outdoor recreation complexes.
By operating out of Nanchong, Sichuan, we leverage structural regional benefits, including integrated local supply loops for fumed silica core elements and raw barrier foils. Furthermore, our parent group, CBVAC, supplies customized vacuum chambers directly, cutting down capital investments for machinery and automation maintenance. This allows us to keep final prices highly competitive without cutting corners on component reliability.
Fiberglass core VIPs are cheaper to produce, but their internal pressure must remain extremely low to maintain thermal efficiency. If the vacuum envelope fails, their conductivity rises immediately to ~0.040 W/(m·K). Fumed silica has much smaller pore structures, meaning that even under total vacuum loss, the panel still maintains a thermal conductivity of ~0.020 W/(m·K), making it much safer and more reliable for architectural and cold chain installations.
We supply specialized VIPs with custom offset steps, or composite options where the VIP is integrated within PU foam layers. Designing layouts with precise drawings prevents the need to cut panels on-site (which destroys the vacuum vacuum instantly), while maximizing continuity of the thermal envelope.
When used in standard architectural settings (embedded within walls, protected from moisture and physical impacts), fumed silica VIPs are rated to maintain optimal vacuum performance for over 50 years. For refrigeration units and mobile cold chain boxes, the operational service life ranges from 15 to 25 years under high rotation cycles.
No. The vacuum core is hermetically sealed within high-barrier film envelope layers. Any cutting, nailing, or deep scratching on site will instantly puncture the film, causing loss of vacuum and degrading thermal performance. Custom shapes, pipe openings, and special corner cuts must be finalized in CAD drawings and manufactured directly in our factory.
Our production facilities are certified under ISO 9001, ISO 14001, and ISO 45001. Our VIPs comply with ASTM and DIN thermal measurement standards, and are regularly tested by third-party testing institutions to guarantee compliance with European CE building regulations and REACH safety acts.
We provide one-stop vacuum insulation system designs. Our team of engineering and logistics experts are ready to evaluate your requirements and offer optimized solutions.
