Explore our core selection of customized vacuum insulation panels engineered for unmatched lifespan expectancy and structural durability.
Vacuum Insulation Panels (VIPs) represent the absolute cutting edge of commercial thermal insulation technology, maintaining thermal conductivity rates (λ) as low as 0.0015 to 0.0020 W/(m·K). However, the central factor governing their large-scale deployment is lifespan expectancy. In industries where assets are expected to run for 30 to 60 years, understanding the degradation curves, moisture intrusion mechanics, and core microstructural developments of VIPs is paramount.
The physical lifespan of a vacuum insulation panel is defined by its ability to preserve an internal vacuum pressure of less than 10 mbar. Over decades, atmospheric gases and moisture slow-diffuse through the barrier envelope. By optimizing barrier film laminations, introducing advanced desiccants, and implementing precise manufacturing seals, industry leaders can extend the thermal performance window of high-tech insulation systems.
At Zerothermo Technology Co., Ltd. (a key subsidiary of the CBVAC Group), we engineer VIPs with advanced core microstructures designed to withstand physical aging processes, offering customized solutions that match the lifetime requirements of architectural facades, thermal batteries, and high-value cold chain containers.

View More +The degradation of a Vacuum Insulation Panel (VIP) is a complex thermodynamic process governed by the laws of mass transport and material aging. Under ideal conditions, a VIP core functions in a high-vacuum state, reducing gaseous thermal conduction to absolute zero. However, in physical applications, atmospheric moisture and gas molecules continually attempt to permeate the panel's barrier envelope.
To model and predict the lifespan expectancy of custom VIPs, engineers focus on two primary degradation pathways: gaseous pressure rise and water vapor accumulation.
The overall thermal conductivity of a VIP, λtot, is defined by the sum of its structural conductivity (λs), radiation transmission (λ_r), and gaseous thermal conductivity (λg). While λs and λr remain relatively constant over time, λg is directly dependent on internal gas pressure. Gaseous heat transport is characterized by the Knudsen number ($Kn$):
Kn = L_m / d
Where L_m is the mean free path of the gas molecules and d is the characteristic pore size of the core. If the pore size is significantly smaller than the mean free path of the gas (resulting in a high $Kn$), gas molecules collide with the pore walls rather than with each other, minimizing thermal conduction even as pressure increases.
This is why fumed silica cores are superior for long-term installations. With an average pore size of 10 to 20 nanometers, fumed silica maintains low thermal conductivity up to an internal pressure of 100 mbar. In contrast, fiberglass cores have micro-sized pores (1 to 10 μm), causing their thermal insulation performance to degrade rapidly once internal pressure surpasses 10 mbar.
Relative humidity (RH) is another key factor. Water vapor entering the VIP increases gaseous thermal conductivity and can also condense within the nanopores of the core. Condensation leads to liquid water bridging, which significantly increases structural thermal conductivity (λs).
To counter this, custom VIP factories integrate specialized desiccants (such as calcium oxide or molecular sieves) and chemical getters directly into the core matrix. These additives absorb moisture and outgassed organic compounds, keeping the internal environment dry and preserving the vacuum for decades.
Procurement requirements for high-performance VIPs vary significantly by sector. Global purchasers must balance mechanical stress, operating temperature range, and target service life:

Maintaining vacuum performance over multiple decades requires ongoing material innovation. Zerothermo's technical roadmap focuses on three main research pathways to optimize lifespan expectancy:
We are researching hybrid core structures that blend nano-porous fumed silica with advanced aerogels. This combination reduces initial thermal conductivity to under 0.0035 W/(m·K) while maintaining the structural stability needed to resist moisture-induced aging.
Next-generation envelopes utilize multi-layered, co-extruded barrier foils with protective inorganic nano-coatings. These advanced films reduce the Gas Transmission Rate (GTR) by a factor of 10, extending the calculated service life of architectural VIPs past the 60-year mark, even in hot, humid climates.
For critical installations, we integrate non-invasive, radio-frequency (RF) sensor tags inside the panel envelope. This allows operators to verify internal vacuum pressure and confirm thermal integrity without damaging the outer barrier.
