View Details →In modern industrial insulation design, spatial efficiency and thermal barrier performance exist in a state of constant compromise. Traditional insulation mediums, such as polyurethane foam (PU), expanded polystyrene (EPS), or mineral wool, rely on gas pockets trapped within their physical structures to retard heat transfer. However, these materials are limited by the thermal conductivity of the static air trapped inside them ($\approx 0.026 \text{ W/m·K}$).
Vacuum Insulation Panels (VIPs) bypass this physical limitation by evacuating gas molecules from the interior core material, thereby raising the Knudsen number ($Kn$) of the system. In a 25mm Vacuum Insulation Panel, the internal core matrix (typically fumed silica or structured fiberglass) is compressed under high pressure and sealed under a high vacuum ($\le 1 \text{ mbar}$) inside a multi-layer high-barrier envelope film. By removing air, gaseous conduction is eliminated, leaving only minimal solid-contact conduction and radiative heat transfer. A 25mm fumed silica VIP achieves a center-of-panel thermal conductivity ($\lambda$) of less than $0.004 \text{ W/m·K}$, offering up to ten times the thermal resistance of traditional insulation materials at identical thicknesses.
While thinner VIP panels (5-15mm) are widely used in commercial consumer products like domestic refrigerators, high-demand industrial systems require greater mechanical resistance, longer service lifetimes, and higher total R-value. A 25mm thickness profile provides the optimal threshold: it presents a highly robust core structure resistant to slight surface compressions, provides exceptional long-term vacuum stability by doubling the core gas storage capacity, and ensures a superior system-level R-value capable of meeting strict carbon-neutral building codes and deep-freeze logistics standards.
As regulatory frameworks globally pivot towards strict decarbonization, the demand for high-efficiency vacuum solutions is undergoing rapid transformation. At Zerothermo Technology, our R&D roadmap targets three primary vectors to extend the application envelope of 25mm VIPs:
Integration of organic-inorganic composite materials within the fumed silica core. By blending low-density aerogel matrices with nano-microporous silica, we aim to lower the initial dry density of the core, thereby reducing physical solid conduction while maintaining structural stability at 25mm.
Moving away from traditional aluminum foil envelopes to ultra-thin, multi-layer metalized polyester (PET) laminates. This reduces the "thermal bridging effect" at the panel edges (linear thermal transmittance $\psi$), which can degrade the total system performance of thick panels. These new films also feature enhanced resistance against gas and moisture permeation, extending panel service life to over 60 years.
Development of panels featuring integrated passive RFID or NFC vacuum pressure sensors. This allows engineers and facility managers to assess the internal pressure of 25mm VIPs in-situ, without dismantling facade systems or transport containers, verifying panel integrity over decades of deployment.
The unique properties of 25mm Vacuum Insulation Panels render them highly suitable for addressing critical thermal challenges across diverse economic sectors:
With the rise of temperature-sensitive biologic drugs and mRNA vaccines, maintaining ultra-cold storage ($ -70^\circ\text{C}$ or $ -20^\circ\text{C}$) during transit is critical. 25mm VIPs installed in shippers provide thermal runtimes exceeding 120 hours without dry ice refilling, optimizing transit security.
In high-density urban areas, wall thickness directly impacts rentable square footage. Replacing 200mm of traditional EPS foam with a 25mm VIP panel achieves the same thermal performance, saving valuable space, facilitating retrofit insulation of heritage facades, and satisfying Class A fire protection requirements.
For industrial piping networks, high-pressure boilers, and steam lines, 25mm microporous and VIP solutions reduce surface radiation heat losses, saving megawatt-hours of fuel and protecting plant personnel from contact burns.
