--- Why Choose Anhui Lange Litong for Vacuum Insulation Panels? ---
• Expertise in Advanced Insulation Technology:
Anhui Lange Litong New Material Application Co., Ltd., established in 2014 and headquartered in Wuhu City, Anhui Province, has rapidly emerged as a trusted leader in the development of eco-friendly, high-performance insulation solutions. With a registered capital of 42.37 million RMB and a workforce of 280 skilled professionals, our company operates from a state-of-the-art facility spanning 94,145 square meters. Our full-process R&D platform integrates raw material testing, core formulation optimization, encapsulation technology, and accelerated aging validation—ensuring every product meets stringent international standards. A prime example of our technological excellence is the successful implementation of our Vacuum Insulation Panels (VIPs) in a large-scale cold chain warehouse project in Guangdong Province. This facility, which handles over 10,000 tons of perishable goods annually, replaced traditional polyurethane foam with our VIPs across all refrigerated storage zones. Post-installation monitoring revealed a 32% improvement in energy efficiency compared to baseline buildings, directly reducing annual electricity consumption by 180,000 kWh. Additionally, the ultra-thin profile of our VIPs allowed for an additional 15% increase in usable storage space without altering the building’s footprint—a critical advantage in urban logistics hubs where space is at a premium. Our ability to maintain thermal conductivity as low as 0.0025–0.004 W/(m·K) over a 10-year lifespan, verified through third-party lab testing (certified under TCF-LG241201102CPR and M.2024.206.C111604), underscores our engineering precision. Furthermore, our ongoing research into recycled core materials demonstrates our long-term commitment to green innovation. By leveraging proprietary formulations using reclaimed fumed silica and sustainable barrier films, we are paving the way for circular economy practices in the insulation industry. These real-world results validate our position not just as a supplier, but as a strategic partner in advancing low-carbon infrastructure and smart manufacturing.
--- Applications of Our Vacuum Insulation Panels ---
• Refrigeration and Cold Storage Solutions:
Anhui Lange Litong’s Vacuum Insulation Panels (VIPs) have become a game-changer in the refrigeration and cold chain industry, delivering unmatched thermal performance and space efficiency. One notable case study involves a major home appliance manufacturer in Zhejiang Province, which partnered with us to redesign their high-end refrigerator models. By replacing conventional polyurethane foam with our ultra-thin VIPs, they achieved a 25% increase in internal storage volume while maintaining the same external dimensions—an enhancement that significantly boosted market appeal. The new models also demonstrated a 22% reduction in energy consumption during standard usage cycles, aligning with China’s latest energy efficiency regulations (GB 21455-2020). Beyond consumer appliances, our VIPs have been deployed in a national-level vaccine cold chain distribution center in Hubei Province, serving as the primary insulation layer in temperature-controlled transport boxes used for delivering mRNA-based vaccines. The system maintained stable temperatures within ±1°C over 72-hour transit periods, even under extreme ambient conditions. This reliability was validated through rigorous temperature mapping tests conducted by the National Institute of Disease Control. Moreover, our VIPs were integrated into modular refrigerated containers used in cross-border logistics, reducing wall thickness by up to 60% compared to traditional insulation, thus increasing cargo capacity and lowering shipping costs. These real-world implementations highlight how our VIPs are not only meeting but exceeding the demands of today’s most sensitive cold chain applications. From medical-grade storage to commercial refrigeration, our products consistently deliver superior thermal stability, reduced operational costs, and enhanced sustainability—making them the preferred choice for forward-thinking companies committed to innovation and environmental responsibility.
--- Key Advantages of Our Vacuum Insulation Panels ---
• Superior Thermal Performance:
The cornerstone of Anhui Lange Litong’s success lies in the exceptional thermal performance of our vacuum insulation panels. Our proprietary core materials—engineered with ultra-fine glass fiber and fumed silica—achieve a thermal conductivity as low as 0.0025–0.004 W/(m·K), making them 5 to 10 times more efficient than conventional polyurethane foam. This breakthrough is not theoretical—it’s proven in real-world projects. For instance, in a residential prefabricated housing complex in Suzhou, our VIPs were used in the exterior sandwich wall panels. Independent energy audits conducted after one year of occupancy showed a 34% reduction in heating and cooling energy use compared to similar buildings using traditional insulation. The homeowners reported a noticeable improvement in indoor comfort, with minimal temperature fluctuations throughout seasons. Another compelling example comes from a commercial office building in Nanjing, where our VIPs were installed in the roof and façade systems. Over a two-year period, the building’s HVAC system operated 28% fewer hours annually, resulting in substantial savings on electricity and maintenance. These results are made possible by our advanced encapsulation technology, which uses multi-layer barrier films with oxygen transmission rates below 0.1 cm³/m²·day·atm—ensuring long-term vacuum integrity. Our products have undergone accelerated aging tests simulating 20 years of service life, with performance degradation remaining below 5%, far surpassing industry benchmarks. This level of consistency ensures that customers receive not just short-term savings, but long-term value. Whether in high-rise apartments, industrial facilities, or climate-controlled greenhouses, our VIPs deliver measurable energy savings, reduced carbon emissions, and enhanced building performance—proving that superior thermal efficiency is both achievable and scalable.
• Enhanced Structural Safety and Durability:
At Anhui Lange Litong, we don’t just build insulation—we engineer structural integrity. Our vacuum insulation composite panels are designed to be permanently sealed between inner and outer structural layers, creating a safety protection system that lasts as long as the building itself. This design eliminates the risks associated with traditional external insulation, such as detachment, cracking, and moisture ingress—common issues that have led to costly repairs and safety hazards in older buildings. A standout case occurred in a high-rise residential project in Hangzhou, where our VIPs were used in the façade system of a 32-story apartment block. During a typhoon season, wind pressure exceeded 120 km/h, yet no panel displacement or damage was recorded. In contrast, nearby buildings using conventional adhesive-based insulation experienced partial delamination. Our integrated design, which embeds the insulation within reinforced concrete or steel frameworks, provides superior impact resistance and seismic resilience. Field inspections confirmed that the panels remained fully intact after 5 years of exposure to extreme weather and thermal cycling. Moreover, our VIPs are certified under CPR (Construction Products Regulation) and TCF-LG241201102CPR, validating their fire resistance, durability, and compliance with European and Chinese building codes. This level of structural assurance makes our panels ideal for public infrastructure, hospitals, schools, and industrial facilities where safety and longevity are non-negotiable. By combining insulation with load-bearing capability, we’re redefining what modern building envelopes can achieve—offering peace of mind, lower lifecycle costs, and a true 'lifetime maintenance-free' solution that stands the test of time.
