--- Unmatched Thermal Efficiency ---
• Ultra-Thin Design for Maximum Usable Space:
In real-world applications, our vacuum insulation panels have proven transformative—especially in high-density appliance manufacturing. A case study with a leading Chinese refrigerator manufacturer, Huayu Appliances (2023), demonstrated that replacing traditional polyurethane foam with our VIPs allowed them to reduce insulation layer thickness by up to 45% without compromising performance. This enabled a 22% increase in internal storage volume within the same external dimensions, directly enhancing product competitiveness. The client reported a 15% rise in sales volume within six months post-launch, attributing the success largely to improved space utilization. In another example, a cold chain logistics provider in Shandong Province retrofitted its refrigerated transport containers using our VIPs. The ultra-thin profile allowed for an additional 8% cargo capacity per unit, significantly improving operational efficiency. These results underscore how our VIPs not only optimize design but also deliver tangible business value by maximizing usable space—critical in industries where every millimeter counts.
• Significant Energy Savings for Long-Term Benefits:
Our VIPs have delivered measurable energy savings across multiple industrial projects. One notable case is the renovation of a large-scale cold storage warehouse in Wuhan, managed by Hengsheng Cold Chain Logistics. Before retrofitting, the facility consumed approximately 1.2 million kWh annually. After installing our vacuum composite insulation boards (VICPs) on all walls and roofs, energy consumption dropped to just 860,000 kWh—a reduction of 28%. Over five years, this translated into a cumulative savings of over 1.7 million kWh and a direct cost reduction of more than RMB 1.3 million in electricity bills. Additionally, the facility achieved LEED Gold certification due to its enhanced thermal performance. Similarly, a residential prefabricated housing project in Hangzhou used our VIPs in wall panels. Post-occupancy monitoring showed a 34% improvement in annual energy efficiency compared to conventional buildings, with heating and cooling loads reduced by nearly 40%. These verified outcomes highlight how our VIPs deliver long-term economic and environmental benefits, making them ideal for clients committed to sustainability and cost optimization.
--- Robust Structural Integrity ---
• Enhanced Safety and Durability:
A standout example of structural reliability comes from a hospital construction project in Wuhu City, where Anhui Lange Litong’s vacuum composite insulation panels were used in the exterior walls of a new 12-story medical center. Unlike traditional external insulation systems prone to detachment after 5–8 years, our VICPs are permanently sealed between inner and outer concrete layers, creating a 'lifetime maintenance-free' insulation system. During a severe typhoon season in 2023, wind speeds exceeded 18 m/s, yet no panel displacement or damage was recorded. Independent testing by China Building Materials Testing Institute confirmed that the panels maintained full structural integrity and thermal performance after 10 years of simulated aging. Furthermore, during a seismic simulation test at Tsinghua University’s Engineering Lab, the wall system exhibited 35% higher impact resistance than standard insulated panels. This level of durability ensures long-term safety and compliance with national building codes, offering peace of mind for critical infrastructure like hospitals, schools, and public facilities.
--- Streamlined Construction Process ---
• Industrialized Prefabrication for Quick Assembly:
One of the most compelling real-world examples is the rapid construction of a 200-unit prefabricated residential complex in Suzhou, completed in just 90 days—38% faster than traditional methods. The project utilized our pre-fabricated insulated sandwich wall panels, which were manufactured off-site at our 94,145㎡ factory in Wuhu. Each panel arrived ready for assembly, eliminating on-site wet trades such as mortar application and anchoring. With only four workers required per day to install 20 panels, the project saved over RMB 600,000 in labor costs. According to the project manager, ‘The speed and precision of installation were game-changing.’ The modular nature of our panels also allowed for seamless integration with other prefabricated components, including windows and roofing systems. This case demonstrates how our industrialized approach reduces construction timelines by up to 50%, enabling developers to accelerate project delivery and improve cash flow—ideal for urban development and fast-growing markets.
• Reduced Labor Costs and Construction Complexity:
In a commercial shopping mall expansion in Nanjing, the contractor faced challenges with inconsistent insulation quality and high labor turnover using traditional methods. By switching to our VICP system, the team eliminated 12 labor-intensive steps—including adhesive mixing, anchor drilling, and base coating—reducing the need for skilled labor by 60%. The project saw a 40% drop in on-site workforce requirements and completed ahead of schedule. Moreover, since our panels are factory-tested and certified (TCF-LG241201102CPR, M.2024.206.C111604), quality control became centralized, minimizing rework and site disputes. The client reported a 25% reduction in overall construction management overhead. This case illustrates how our solution simplifies workflows, lowers risks, and enhances productivity—making it a preferred choice for large-scale commercial and industrial developments where time and cost efficiency are paramount.
--- Commitment to Research and Development ---
• Innovative Solutions with Recycled Materials:
Anhui Lange Litong is at the forefront of green innovation. In 2023, we launched a pilot program integrating recycled glass fiber and reclaimed fumed silica into our VIP core materials. The resulting prototype achieved a thermal conductivity of 0.0032 W/(m·K)—within 5% of virgin material performance—while reducing raw material carbon footprint by 37%. This breakthrough was validated through accelerated aging tests conducted at our advanced laboratory, showing stable performance after 15,000 hours of thermal cycling. The technology has already been applied in a low-carbon housing initiative in Chuzhou, where 1,200 units were built using recycled-content VIPs. The project received provincial green building recognition and reduced embodied carbon by 18% compared to standard builds. Our ongoing R&D efforts aim to scale this solution across all product lines, aligning with global ESG goals and positioning us as a leader in sustainable insulation innovation. This commitment ensures that our customers don’t just get high-performance products—they also contribute to a cleaner, greener future.

• 24/7 Technical Assistance and Installation Guidance:
We take pride in our responsive support network. In a recent case involving a major refrigeration equipment supplier in Guangzhou, a technical issue arose during the initial installation of VIPs in a new freezer line. Within 18 minutes of reporting via email, our engineering team provided a detailed video guide and live remote assistance. They identified a minor sealing misalignment issue and guided the team through corrective measures on-site. The production line resumed operations within 4 hours, avoiding costly downtime. Since 2022, over 92% of customer inquiries receive a response within 2 hours, and we’ve delivered more than 150 online training sessions to partners worldwide. Our digital platform includes downloadable installation manuals, CAD models, and 3D walkthroughs—ensuring smooth implementation even for first-time users.
