Vacuum Sealed Insulation Panels (VIPs) represent a monumental breakthrough in thermal engineering, offering thermal performance that is up to ten times greater than traditional insulation materials. By encapsulating a highly porous core material—most commonly fumed silica or fiberglass—within a gas-tight envelope, and drawing a high vacuum, conductive and convective heat transfer modes are almost entirely eliminated.
For global enterprise procurers, VIPs are transitioning from a premium novelty to a baseline technical requirement. This shifts the focus to selecting a qualified vacuum insulation panel factory capable of maintaining strict seal integrity and core density control over massive scale production runs.
With the aggressive scaling of the cold chain for temperature-sensitive pharmaceuticals and the rise of carbon-neutral mandates in commercial architecture, manufacturing compliance has become paramount. Leading factories must implement automated helium leak testing and laser-based surface inspection systems.
Furthermore, in high-temperature applications (such as elevator fireproof doors or water heaters), nano microporous matrices provide an extra layer of thermal and physical integrity, retaining insulation capacities under demanding thermal loads.

Frequently Asked Technical Questions
A world-class factory must operate clean-room core fabrication environments to prevent dust contamination, which compromises envelope seals. Further, they must deploy state-of-the-art inline quality control systems, including automated chamber pressure checks and Helium Mass Spectrometry leak detection. Zerothermo utilizes CBVAC Group’s advanced vacuum system engineering to guarantee long-term vacuum stability.
Fumed silica core material features incredibly small pore sizes (~10 nanometers) compared to glass fibers. If the vacuum envelope suffers minor gas permeation over decades, the fumed silica core retains much of its insulation capacity. In contrast, fiberglass VIPs experience rapid thermal performance degradation when vacuum levels drop, making fumed silica the safer choice for a 50+ year architectural lifespan.
No. Because VIPs depend on a deep vacuum sealed within a multi-layer gas barrier film, they cannot be cut, drilled, or nailed on-site. Doing so will immediately compromise the vacuum seal, raising the thermal conductivity to that of the ambient pressure core material. Consequently, precise shop drawings and custom-sized panel layouts must be produced by the manufacturer before fabrication.
Thermal bridging occurs at the joints between VIP panels because the barrier film (especially layers containing aluminum foil) has a higher thermal conductivity than the vacuum core. Selecting a manufacturer that offers optimized multi-layer metallic-PET barrier films or staggered-joint panel layouts significantly reduces the linear thermal transmittance (Ψ) across the envelope.
In New Energy Vehicles (NEVs), space is limited. Standard insulation materials are too bulky. Thin-profile VIP thermal blankets limit heat transfer between adjacent battery cells. This prevents a failing cell from reaching critical temperatures and causing thermal runaway across the entire pack.
Lifespans are calculated using accelerated aging tests (Arrhenius models) under high temperature and humidity. These tests track gas and moisture transmission rates through the barrier film. Our fumed silica VIPs are designed to maintain a thermal conductivity of less than 0.008 W/(m·K) over 50 years under standard building environments.
