In thermal design, the standard metric of performance is the R-Value (thermal resistance) or its SI equivalent, the Thermal Conductivity (λ-value). Standard materials like Polyurethane (PU) or Mineral Wool rely on trapping gas within a fibrous or porous matrix. However, gas conduction remains a primary mechanism of heat transfer. Zerothermo Technology systematically eliminates gas conduction by evacuating the panel core down to a range of 0.1 to 1 mbar, allowing our panels to achieve R-values up to R-50 per inch.
The core material, whether fumed silica or fiberglass, acts as a structural spacer keeping the barrier films apart under extreme atmospheric pressure. Under high vacuum, the mean free path of the remaining gas molecules exceeds the size of the microscopic pores (the Knudsen effect), effectively reducing the gas thermal conductivity to zero.
| Insulation Type | Core Thermal Conductivity (λ) (W/m·K) | R-Value per Inch (h·ft²·°F/Btu) | Typical Lifetime (Years) | Space Requirements (relative) |
|---|---|---|---|---|
| Zerothermo VIP (Fumed Silica Core) | 0.004 - 0.005 | R-35 to R-45 | 30 - 50+ | 1x (Extremely Thin) |
| Zerothermo VIP (Fiberglass Core) | 0.0015 - 0.0025 | R-50 to R-65 | 15 - 20 (Depending on environment) | 0.5x (Ultra-Thin) |
| Polyurethane (PU) / PIR | 0.022 - 0.028 | R-6.0 to R-7.2 | 10 - 20 (Degrades over time) | 6x to 8x Thicker |
| Expanded Polystyrene (EPS) | 0.033 - 0.038 | R-3.8 to R-4.2 | 15 - 25 | 10x to 12x Thicker |
| Mineral Wool | 0.035 - 0.040 | R-3.2 to R-3.8 | 30+ | 12x to 15x Thicker |
By achieving pressures below 1 mbar, the molecular collision mechanism of gases is broken, eliminating bulk convection and conduction inside the panel.
The core material is mixed with custom opacifiers (such as silicon carbide or titanium dioxide) to scatter and block infrared radiative heat transfer.
Our film wraps consist of multiple layers of metalized PET, EVOH, and aluminum foil, keeping the moisture vapor transmission rate (MVTR) near zero for decades.

Achieving regulatory compliance, reducing carbon footprint, and preventing thermal leakage globally.
Critical biological agents, vaccines, and cell therapies require strict thermal protection during transcontinental transport. Zerothermo VIPs provide the thermal stability to sustain temperature zones from 2°C to 8°C and down to ultra-cold deep-freeze zones (−70°C) without relying on heavy electrical refrigeration power.
With real estate development focusing heavily on reducing carbon emissions, architects integrate VIPs into external envelopes, balconies, and internal floors. By delivering extreme R-values in a fraction of the thickness of EPS, projects conserve rentable square footage while maintaining strict net-zero performance.
Specialized industrial ovens, laboratory autoclaves, and high-integrity fireproof elevator structures require microporous nano-composite linings. These systems restrict intense heat loads (up to 1000°C) within active processing cores, shielding outer enclosures and neighboring electrical systems from heat degradation.
