The thermal conductivity of vacuum insulation panels can generally be as low as 0.002-0.004W/(m · K), which is much lower than that of traditional insulation materials such as polystyrene boards, rock wool, and polyurethane. It is currently one of the insulation materials with the best thermal insulation performance.
Description
Due to its extremely low thermal conductivity, vacuum insulation panels can effectively prevent heat transfer, significantly reducing heat loss or transmission in buildings, refrigerators, cold storage facilities, etc., thereby lowering energy consumption and achieving the goal of energy conservation. Under the condition of achieving the same heat insulation effect, the thickness of vacuum insulation boards is much thinner than that of traditional insulation materials. For instance, a thin vacuum insulation board can achieve the same insulation effect as a 10-centimeter traditional insulation material, which can save a considerable amount of space in fields such as construction and home appliances.
The thin and light characteristics of vacuum insulation panels make them small in size and light in weight. They are not only convenient for transportation and installation, but also can reduce the overall weight of buildings, equipment, etc. This is of great significance in some occasions where weight is required, such as aerospace, shipping and other fields.
Specifications: 400mm*600mm, 300mm*600mm, 200mm*400mm; thickness: 1.0cm, 1.3cm, 1.5cm, 1.7cm, 2.0cm, 2.3cm, 2.5cm, 2.7cm, 3.0cm, etc.; shape and size can be customized.
Vacuum Insulation Panels (VIPs) are advanced thermal insulation materials designed to achieve ultra-low heat transfer by using vacuum technology. Each panel features a micro-porous core material—typically fumed silica or aerogel composite—sealed within a high-barrier envelope under vacuum conditions. This structure minimizes conduction and convection, resulting in thermal conductivity values as low as ≤0.004 W/m·K, which is nearly 10 times lower than that of conventional insulation materials such as polyurethane foam (PU) or expanded polystyrene (EPS). Thanks to their outstanding insulation performance and slim structure, Vacuum Insulation Panels are widely applied in refrigeration systems, cold chain transport, energy-efficient buildings, and industrial equipment requiring precise temperature control.
Vacuum Insulation Panels operate by reducing the number of air molecules that can transfer heat. The core material—typically nano-structured silica or aerogel composite—provides a highly porous matrix with minimal solid conduction.
1. Core Composition: Fumed silica or aerogel composite offering high thermal resistance.
2. Barrier Film: Multi-layer aluminum-coated PET that maintains internal vacuum and prevents gas or moisture ingress.
3. Edge Sealing: Heat-sealed perimeter ensuring long-term vacuum stability and structural strength.
This configuration ensures exceptional insulation performance even at thin thicknesses and guarantees 15 years or more of effective service life under standard operating conditions.

Q1: What makes Vacuum Insulation Panels different from traditional insulation boards?
VIPs use vacuum and nano-structured cores to drastically reduce heat transfer, achieving up to 10 times higher insulation efficiency than conventional materials like PU or EPS.
Q2: How long does the insulation performance last?
Under standard usage conditions, the panels maintain vacuum stability and high insulation efficiency for 15–20 years.
Q3: Can Vacuum Insulation Panels be trimmed on-site?
No. Cutting or drilling the panel damages the vacuum layer. Panels should be manufactured to exact sizes before installation.
Q4: What thickness is recommended for building applications?
For exterior walls and roofs, 20–30 mm VIPs can achieve thermal performance comparable to 200 mm of traditional insulation.
Q5: Are the panels suitable for outdoor environments?
Yes, when properly encapsulated or installed behind protective surfaces. The barrier film itself resists moisture and UV exposure but should be shielded from physical damage.
