Explore Tech DetailsThermal transmission in porous insulation materials occurs via three main vectors: solid conduction, gas conduction, and radiation. In standard materials such as polyurethane foam or expanded polystyrene (EPS), gas conduction dominates due to the atmospheric air trapped inside cell micro-cavities. Vacuum Insulation Panels (VIPs) virtually eliminate this major thermal transfer mode by evacuation, bringing the core's interior pressure down to a fine range between 1 and 10 mbar.
By applying the Knudsen Effect, when the mean free path of gas molecules becomes larger than the structural pore dimensions of the core, molecular collisions are restricted. The fumed silica core's nanoscale structure, with pore diameters averaging 10 to 20 nm, easily blocks molecular gas conduction even at partial vacuum levels. As a result, VIP thermal conductivity values drop to as low as 0.004 W/(m·K) to 0.005 W/(m·K). This performance is roughly five to ten times better than typical polymer foams.
Core material choice defines the panel's performance profile, pricing structure, and aging cycle. Fumed silica cores offer high thermal stability and maintain their insulating properties even when vacuum degradation occurs slowly over several decades. Fiberglass cores offer lower initial thermal conductivity values but require higher vacuum pressures (< 1 mbar) and are more susceptible to performance loss over time without high-barrier barrier films.
| Core Material Type | Core Pore Size | Initial Conductivity | Expected Lifespan |
|---|---|---|---|
| Fumed Silica Core | 10 - 20 nm | 0.004 W/(m·K) | Up to 50 Years |
| Fiberglass Core | 1 - 10 µm | 0.0015 W/(m·K) | 10 - 15 Years |
| PU Rigid Foam | 30 - 150 µm | 0.022 W/(m·K) | Varies (Aging) |
| Aerogel Blanket | 10 - 40 nm | 0.015 W/(m·K) | Up to 30 Years |
Note: Values are measured at 25°C mean temperature. Real world thermal aging depends heavily on ambient relative humidity and installation environments.

Why global OEMs and engineering firms choose Zerothermo Technology for high-performance insulation projects.
Global procurement teams must navigate local building codes, transportation safety rules, and environmental regulations. Our vacuum insulation panels comply with international standards like CE, RoHS, and REACH, verifying they contain no hazardous materials and are suitable for cleanroom and pharmaceutical storage environments.
To support global logistics, our packaging is built to withstand ocean shipping conditions. We package products in heavy-duty, moisture-sealed wooden crates with shock indicators to maintain internal vacuum integrity during transit. We also offer customs clearance assistance to streamline imports into European, North American, and Asia-Pacific ports.
Additionally, we work closely with engineering teams during the integration process. Because VIPs cannot be cut, drilled, or altered post-production, we assist with precise layout planning and CAD coordination before manufacturing begins. This helps eliminate installation issues and ensures maximum thermal performance on-site.

Technical answers regarding vacuum insulation panels, core structures, thermal performance, and pricing variables.
Our VIP pricelist is influenced by several factors: core material type (fumed silica commands a premium over fiberglass due to its longer service life), panel dimensions, envelope film specifications (multi-layer laminate vs. basic film), shape complexity (notched or curved profiles), and order volume. Custom dimensions require specialized sealing parameters, which can affect pricing compared to standard sizes.
Fumed silica core materials have small nano-pores (10 to 20 nm) that limit gas conduction even if the internal vacuum pressure degrades over time. In contrast, fiberglass cores have larger micro-pores, making them reliant on maintaining a very high vacuum level (< 1 mbar). If air or moisture penetrates the barrier film, a fiberglass panel's thermal conductivity can rise quickly, while a fumed silica panel maintains much of its insulation value.
No, VIPs cannot be cut, drilled, or reshaped after manufacturing. The panel relies on a hermetically sealed barrier envelope to maintain its internal vacuum. Puncturing this skin releases the vacuum, causing the thermal conductivity to rise to that of the unevacuated core material (approximately 0.020 W/(m·K)). All dimensions and cutouts must be planned during the design phase and manufactured to size at the factory.
To reduce thermal bridging at panel borders, we use multi-layer installation techniques, staggered layout patterns, or high-efficiency foam tape along the joints. Some architectural configurations combine VIPs with a thin layer of traditional insulation (like PIR or PU foam) to cover the joints and create a continuous thermal barrier.
Under typical ambient temperature and humidity levels, our fumed silica VIPs are designed to last between 30 and 50 years. This performance is sustained by using thick outer barrier foils and integrated getters that absorb residual moisture and gases over the lifetime of the installation.
