View DetailsIn modern industrial design, space is the ultimate constraint. Traditional insulation materials like polyurethane (PU) foam, mineral wool, or expanded polystyrene (EPS) require thicknesses ranging from 30mm to 100mm to achieve structural energy targets. However, the emergence of Vacuum Insulation Sheets (3mm thickness) has changed the paradigm of thermal engineering, delivering equivalent thermal protection at a fraction of the physical footprint.
Thermal conduction operates through three mechanisms: solid conduction, gas convection, and radiative transport. Inside a Vacuum Insulation Panel (VIP), a porous core material is enclosed in an airtight envelope, and the air is evacuated. Because gas molecules are virtually eliminated, gas thermal conduction is reduced to zero. The residual heat transfer is determined by the solid conduction of the core and radiation. At a thickness of only 3mm, fumed silica or micro-fiber glass cores are highly engineered to minimize solid contact points while blocking infrared radiation, achieving an ultra-low thermal conductivity ($\lambda \le 0.004 \text{ W/(m}\cdot\text{K)}$).
| Material Type | Standard Thickness (mm) | Thermal Conductivity (W/m·K) | Space Savings (%) |
|---|---|---|---|
| Fumed Silica VIP (Thin) | 3mm - 5mm | 0.004 - 0.005 | 90% - 95% | 35mm - 50mm | 0.022 - 0.028 | Baseline |
| Expanded Polystyrene (EPS) | 50mm - 80mm | 0.032 - 0.038 | -30% (Thicker) |
| Rockwool / Glasswool | 70mm - 100mm | 0.036 - 0.044 | -50% (Thicker) |
When selecting a 3mm vacuum insulation sheet, engineering teams must evaluate the two primary core structures available on the market:
Features an average nano-pore size of 10 to 20 nanometers. This structural characteristic ensures the panel maintains its thermal performance even if the internal vacuum pressure rises slightly over time (often up to 100 mbar). It is suitable for applications requiring a 20+ year service life, such as architecture and high-temperature systems.
Utilizes ultra-fine glass fibers to create a rigid, highly compressed core. It achieves a low initial thermal conductivity of approximately 0.002 W/m·K under high vacuum conditions. However, it is sensitive to moisture and gas permeation, making it suitable for sealed systems like refrigerators or short-cycle cold chain systems.

As international energy policies align with carbon-neutrality targets, procurement teams face pressure to identify insulation solutions that minimize space while maximizing thermal resistance. The demand for 3mm vacuum insulation sheets is growing, particularly in high-density applications where traditional thick panels cannot be used.
Industrial procurement leads require clear evidence of quality and performance compliance from VIP manufacturers. Key testing parameters include:
Manufacturing ultra-thin 3mm VIPs requires precise process controls. Thin cores must be compressed uniformly to avoid internal stress points that can puncture the barrier envelope. Chinese manufacturing centers, such as Zerothermo's Nanchong base, utilize automated lamination, laser cutting, and robotic vacuum chamber sealing. This continuous production minimizes human error, providing consistent density, flatness, and edge-sealing across production runs.
Vacuum insulation technology provides solutions for energy conservation, thermal safety, and temperature stability across multiple sectors.
Provides thermal protection for temperature-sensitive biologics and vaccines in space-constrained shipping containers.
Integrates into curtain walls, floor structures, and window frames to reduce thermal bridging in green building envelopes.
Serves as thermal backing insulation in industrial furnaces, kilns, and high-temperature process piping.
Utilized in prefabricated structures, mobile cabins, and specialized transit equipment requiring lightweight insulation.
