The core science of the Vacuum Insulation Principle (VIP) is based on eliminating the medium through which thermal energy is transferred. In typical thermal insulation barriers, heat is moved by a combination of solid conduction, gas convection, and radiative transmission. By evacuating the internal gas from a highly porous core substrate, gas convection and gas molecular conduction are almost entirely eliminated.
According to the Knudsen physical rule, when the mean free path of the remaining gas molecules exceeds the average pore size of the core material, gas molecules cannot move easily. They collide with the cell walls of the core substrate rather than with each other, dropping the gas thermal conductivity to almost zero.
This results in VIP materials achieving an incredibly low thermal conductivity—often below 0.002 W/(m·K)—which is up to ten times more efficient than traditional insulating materials like EPS or mineral wool. This level of efficiency allows industries to save energy and optimize storage capacity in space-critical applications.
| Core Material Base | Pore Dimension (Typical) | Internal Pressure Limit | Thermal Conductivity (Initial) | Estimated Service Life |
|---|---|---|---|---|
| Fumed Silica (Nano-porous) | 10 - 100 nm | < 50 mbar | ≤ 0.004 W/(m·K) | Over 30 Years |
| Fiberglass (Micro-fiber) | 1 - 10 μm | < 1 mbar | ≤ 0.002 W/(m·K) | 10 - 15 Years |
| Polyurethane (PU Foam) | 30 - 100 μm | < 0.1 mbar | ≤ 0.008 W/(m·K) | 5 - 8 Years |

Our production facility is equipped with automated vacuum sealing chambers, continuous inline thermal performance testing, and multi-layer film laminators to ensure quality and performance across our product range.
Our path to developing next-generation thermal barriers, expanding vacuum limits, and improving material durability.
Research is currently focused on combining micro-fiber glass matrix structures with organic fumed silica binders. This hybrid approach aims to lower manufacturing costs while maintaining low thermal conductivity (around 0.0015 W/(m·K)). By optimizing core density, we can also improve structural rigidity and make the panels easier to handle on-site.
Additionally, we are developing bio-derived porous carbons to replace synthetic silica cores, helping to reduce the overall carbon footprint of VIP production.
To ensure long-term performance, we are integrating thin-film RFID sensor tags inside the vacuum envelope. These sensors allow operators to verify the internal vacuum pressure of panels during logistics or after building installation without compromising the barrier film. This enables preventative maintenance and provides clear proof of panel integrity throughout its service life.
