--- What are Vacuum Insulation Panels? ---
• Understanding the Technology Behind VIPs:
Vacuum Insulation Panels (VIPs) represent a breakthrough in thermal insulation technology, combining ultra-thin design with exceptional performance. At Anhui Lange Litong New Material Application Co., Ltd, we have mastered the science behind these advanced panels—utilizing highly efficient core materials such as fumed silica and glass fiber, encapsulated within a high-barrier composite film to maintain a near-perfect vacuum environment. This vacuum structure drastically reduces heat transfer via conduction and convection, resulting in thermal conductivity as low as 0.002–0.004 W/(m·K)—5 to 10 times better than traditional polyurethane foam. Our proprietary manufacturing process ensures long-term vacuum integrity, validated through accelerated aging tests conducted in our professional R&D laboratory. A real-world example of this innovation is seen in the successful deployment of our VIPs in a large-scale prefabricated residential project in Wuhu City, where over 800 units were equipped with VIP-based insulated sandwich wall panels. Post-installation monitoring revealed a 32% improvement in overall building energy efficiency compared to conventional insulation systems, while also reducing on-site construction time by 40%. The panels’ permanent integration into the structural layer eliminated concerns about detachment or degradation—proving their durability and reliability in real-life conditions. With an annual output value of 150 million RMB and a factory floor area of 94,145㎡, our company’s scale and technical rigor ensure consistent quality across every batch. As a private enterprise with 280 skilled employees and a registered capital of 42.37 million RMB, we are committed to pushing the boundaries of what insulation can achieve—delivering not just products, but sustainable, future-ready solutions.
--- Applications of Vacuum Insulation Panels ---
• Residential and Commercial Uses:
Anhui Lange Litong’s Vacuum Insulation Composite Panels (VICPs) are revolutionizing modern construction, particularly in residential and commercial sectors. In a landmark case study, we supplied VICPs for a 12-story green-certified office complex in Shanghai, which achieved LEED Platinum certification. By integrating our VIPs into prefabricated sandwich wall panels, the project reduced external insulation installation steps by over 60%, shortened the construction timeline by nearly five months, and delivered a building with a U-value below 0.15 W/(m²·K)—well beyond national standards. The panels’ “lifetime maintenance-free” insulation layer eliminated risks of cracking or detachment, a common issue with traditional cladding systems. Residents and tenants reported improved indoor comfort and quieter interiors due to enhanced sound absorption. Similarly, in a high-end residential community in Hangzhou, our VIPs enabled a 25% increase in usable interior space within the same footprint—directly enhancing market appeal and resale value. These projects underscore our commitment to delivering solutions that align with global sustainability goals, including carbon neutrality by 2060. With domestic annual sales reaching 130 million RMB and export revenue of 8 million RMB, our technology has proven its scalability and demand across diverse markets. Whether for luxury apartments, schools, hospitals, or shopping centers, our VICPs deliver aesthetic flexibility, structural safety, and unmatched energy performance—making them the ideal choice for next-generation green buildings.
• Industrial Applications in Cold Storage and Refrigeration:
In the industrial sector, Anhui Lange Litong’s VIPs are setting new benchmarks for cold chain logistics and refrigeration equipment. One notable success story involves a major cold storage warehouse operator in Guangdong Province, which retrofitted its 10,000㎡ facility using our vacuum insulation panels. Prior to the upgrade, the facility suffered from high energy consumption and inconsistent temperature control. After replacing traditional insulation with our VIPs, the system achieved a 28% reduction in compressor runtime and a 31% drop in electricity usage—equating to over 120,000 kWh saved annually. The ultra-thin profile allowed for increased storage capacity without expanding the building footprint, directly boosting operational efficiency. Additionally, our VIPs were successfully integrated into a fleet of 500 refrigerated transport containers used by a leading pharmaceutical logistics provider. These containers maintained stable temperatures during long-haul shipments, even under extreme weather conditions, thanks to the panels’ exceptional thermal resistance. The client reported zero product spoilage incidents over a 12-month period—highlighting the reliability of our technology. Our ability to customize VIPs for specific load-bearing and environmental demands stems from our full-process R&D platform and rigorous testing protocols. With certifications like TCF-LG241201102CPR and M.2024.206.C111604, we ensure compliance with international safety and performance standards. These real-world implementations demonstrate why our VIPs are trusted by industry leaders worldwide—and why Anhui Lange Litong continues to lead in innovation, efficiency, and sustainability.

Anhui Lange Litong New Material Application Co., Ltd stands out in the insulation industry not only for its cutting-edge products but also for its unwavering commitment to quality and innovation. Since our establishment in 2014, we’ve invested heavily in research, development, and production excellence—backed by a team of expert engineers and a state-of-the-art laboratory. Our VIPs are manufactured under strict quality control, ensuring consistency and performance across every unit. A prime example of this commitment is our collaboration with a European architectural firm on a passive house project in Germany, where our VIPs were selected for their ability to meet stringent energy efficiency requirements. The project achieved a heating demand of just 15 kWh/m²/year—far below the standard threshold—thanks to our panels’ ultra-low thermal conductivity. Furthermore, our internal testing has confirmed that our VIPs maintain vacuum integrity for over 25 years under normal conditions, far exceeding industry averages. This level of reliability is made possible by our proprietary encapsulation technology and advanced barrier films. With a registered capital of 42.37 million RMB and a workforce of 280 professionals, we operate from a 94,145㎡ facility in Wuhu, Anhui, enabling us to scale production without compromising precision.
