Product Description

Ü Vacuum insulation panels (VIPs) play a crucial role in a range of applications, as detailed below, but primarily applied within the buildings and construction sectors that significantly enhance thermal insulation performance compared to traditional insulation materials. These panels consist of a core material (either super-fine fiberglass with getter/desiccant or microporous fumed silica) enclosed in a gas-tight envelope, creating a vacuum pressure of ≤ 1 Pa that greatly reduces heat transfer through conduction and convection. The importance of VIPs in the construction industry lies in their ability to improve energy efficiency, reduce carbon emissions, and enhance comfort within buildings.


Ü In cold-arid regions, where heating is a primary concern, VIPs help minimize heat loss by providing superior insulation. Traditional insulation materials like XPS, EPS, mineral wool or polyurethane may be thicker and less efficient, requiring more space and materials to achieve the same level of insulation.  VIPs, on the other hand, boast extremely low thermal conductivity, with 15 mm thick fiberglass VIPs having a thermal conductivity of ≤ 2.5 mW/(mK) and 25 mm thick fumed silica VIPs having a thermal conductivity of ≤ 4.5 mW/(mK), allowing for thinner insulation layers while maintaining high insulation performance. This saves space in construction and reduces the overall energy consumption needed to keep buildings warm. By minimizing heat loss, VIPs contribute to lower energy demand, thereby reducing carbon emissions associated with heating systems powered by fossil fuels.


Ü Similarly, in hot-arid regions where cooling is a significant energy demand, VIPs help to minimize cooling loss by preventing the transfer of heat from outside to the interior of buildings. Air conditioning systems often work overtime in hot climates to maintain comfortable indoor temperatures, leading to high energy consumption and increased carbon emissions. By incorporating VIPs into building envelopes, the need for cooling is reduced as the panels effectively block heat transfer, keeping interiors cooler for longer periods. This results in lower energy consumption for cooling, thereby mitigating carbon emissions associated with the operation of air conditioning systems powered by fossil fuels.


Ü Hence, the use of vacuum insulation panels in building construction offers a sustainable solution for minimizing carbon emissions caused by heat loss in cold-arid regions and cooling loss in hot-arid regions. By improving energy efficiency and reducing the reliance on heating and cooling systems, VIPs contribute to a more environmentally friendly built environment while also enhancing comfort and reducing operating costs for building occupants.

FAQs about Vacuum Insulation Panel (VIP) with Flexible Design Options

VIPs are advanced insulation materials that consist of a core material (like super-fine fiberglass or microporous fumed silica) enclosed in a gas-tight envelope, under a vacuum pressure of ≤ 1 Pa. This vacuum significantly reduces heat transfer through conduction and convection, offering superior insulation performance. Think of it like an incredibly efficient thermal flask that keeps your drink hot or cold by preventing heat from getting in or out.

VIPs have extremely low thermal conductivity, making them much more efficient than traditional materials like XPS or mineral wool. For example, a 15 mm thick fiberglass VIP has a thermal conductivity of ≤ 2.5 mW/(mK), allowing for thinner layers with higher insulation performance. This means buildings can be insulated more effectively without losing valuable space, ultimately reducing energy consumption and carbon emissions.

In both cold and hot climates, VIPs minimize heat loss or gain, reducing the need for heating or cooling. This lowers energy consumption and, consequently, carbon emissions from fossil fuel-powered systems. It's like wearing a high-performance thermal jacket; you stay comfortable inside without having to constantly adjust the heating or cooling, leading to significant energy savings.

Absolutely! VIPs are versatile and can be adapted to various shapes, sizes, and geometries, making them suitable for new constructions as well as retrofitting existing buildings. Whether you're designing a modern home or upgrading an old office building, VIPs can be tailored to meet specific insulation needs without compromising on space or aesthetics.

Yes, VIPs come in two main types: fiberglass with getter/desiccant and fumed silica. Each has its unique properties, like thermal conductivity and weight, making them suitable for different applications. For instance, fiberglass VIPs might be preferred for lightweight needs, while fumed silica VIPs could be chosen for their slightly better insulation performance.

Indeed, VIPs typically have a high fire rating of A, meaning they're non-combustible and enhance fire safety in construction applications. This adds an extra layer of security to buildings, much like a fire-resistant safe protects valuable documents in a fire.

While the initial investment in VIPs might be higher than traditional materials, the long-term energy savings and environmental benefits they offer make them a cost-effective solution. Think of it as investing in a high-quality appliance that uses less electricity; the upfront cost is higher, but the energy savings over time make it worth it.
