Why Choose Vacuum Insulation Panels for Your Projects?
--- Unmatched Thermal Performance ---
• Ultra-Thin Design for Maximum Usable Space:
Anhui Lange Litong New Material Application Co., Ltd. has successfully implemented vacuum insulation panels (VIPs) in a high-density residential project in Wuhu City, Anhui Province, where space optimization was critical. The project involved the construction of 12 prefabricated modular homes designed for urban micro-living units. By replacing traditional 100mm polyurethane foam insulation with 25mm VIPs, the company achieved the same thermal performance while freeing up an additional 75mm of internal space per wall—equivalent to a 15% increase in usable living area across each unit. This breakthrough allowed developers to offer larger interior layouts without expanding building footprints, significantly enhancing market appeal. According to post-installation thermal testing conducted by the China Building Energy Efficiency Research Institute, the VIP-equipped units demonstrated a U-value of just 0.12 W/(m²·K), surpassing national Grade A energy efficiency standards by over 30%. Furthermore, the ultra-thin profile enabled seamless integration with modern architectural designs, eliminating the need for bulky insulation layers that compromise aesthetic continuity. As one client noted, 'The difference in interior space made our units feel like luxury apartments despite being compact.' This real-world application underscores how VIPs deliver unmatched thermal performance while maximizing functional space—an ideal solution for urban developers striving for both efficiency and livability.
--- Durability and Structural Integrity ---
• Enhanced Safety with Integrated Insulation:
In a landmark case study from 2023, Anhui Lange Litong deployed its Building Vacuum Insulation Composite Panels (VICP) in a newly constructed hospital wing in Hefei, Anhui. The project required a fire-resistant, long-term maintenance-free insulation system capable of withstanding harsh environmental conditions and frequent use. Traditional external insulation systems had previously failed in similar projects due to adhesive degradation and panel detachment caused by temperature fluctuations and moisture infiltration. However, Lange Litong’s VICP system, which permanently seals the vacuum core between inner and outer structural layers, eliminated these risks entirely. Over two years of monitoring, no signs of delamination or thermal bridging were detected, even during extreme seasonal shifts. Independent lab tests confirmed that the insulation layer remained fully intact and maintained its original thermal conductivity. Notably, the hospital’s HVAC system reported a 28% reduction in energy consumption compared to baseline models, directly attributable to the stable insulation performance. This case exemplifies how integrated VIP technology transforms safety and reliability in mission-critical infrastructure. By embedding the insulation within the structural envelope, Lange Litong ensures that the insulation lasts as long as the building itself—offering peace of mind to architects, engineers, and facility managers alike.
• High Impact Resistance for Long-Term Use:
A commercial complex in Shanghai recently faced challenges with exterior insulation damage caused by typhoon-force winds and falling debris. After experiencing multiple repair cycles with conventional insulated panels, the management team turned to Anhui Lange Litong’s VICP system for a full façade retrofit. The new system underwent rigorous impact resistance testing at the National Building Materials Testing Center, simulating wind speeds exceeding 150 km/h and repeated impacts from steel balls equivalent to hailstones. Results showed zero failure or deformation after 500 test cycles—far exceeding industry benchmarks. Since installation, the building has endured three severe storms without any visible damage to the insulation layer. The enhanced structural integrity is attributed to the composite design, where the VIP core is embedded within reinforced concrete and steel frameworks, creating a monolithic wall system. This resilience not only extends the lifespan of the building envelope but also reduces lifecycle maintenance costs by up to 40%. For property owners focused on long-term value, this real-world validation proves that Lange Litong’s VIPs aren’t just about insulation—they’re about building durability, safety, and cost-efficiency over decades.
--- Streamlined Construction Processes ---
• Reduced Project Timelines through Prefabrication:
Anhui Lange Litong partnered with a major real estate developer to construct a 30,000㎡ mixed-use complex in Nanjing, leveraging prefabricated insulated sandwich wall panels based on their VIP technology. Traditionally, such projects would require 6–8 weeks for on-site insulation work involving multiple trades: base preparation, adhesive application, anchoring, and coating. However, by utilizing pre-assembled VICP panels manufactured in Lange Litong’s 94,145㎡ factory in Wuhu, the project completed all exterior wall installations in just 12 days—cutting the timeline by over 50%. The panels were delivered ready-to-install, with precise alignment and sealed joints, minimizing on-site adjustments. This accelerated schedule allowed the developer to move into the next phase of construction earlier, reducing financing costs and accelerating revenue generation. Moreover, the reduced wet trades minimized weather delays and labor disruptions. Post-project analysis revealed that the construction team saved approximately 4,200 labor hours compared to conventional methods. This case demonstrates how VIP-based prefabrication isn’t just a technological upgrade—it’s a strategic advantage for developers aiming to deliver faster, higher-quality projects in competitive markets.
• Simplified Installation and Labor Cost Savings:
In a rural school renovation project in Anhui Province, local contractors struggled with inconsistent quality and high labor demands when installing traditional insulation systems. When the project switched to Anhui Lange Litong’s VIP-based insulated wall panels, the results were transformative. The installation process was simplified to a single-step mounting procedure—panels were lifted into place and secured with minimal fasteners. Training sessions provided by Lange Litong’s technical team ensured that unskilled workers could complete installations safely and accurately within hours. The project saw a 60% reduction in labor costs and a 70% decrease in on-site supervision needs. Additionally, since there was no need for adhesives or curing time, work could proceed year-round regardless of weather. The school now enjoys a thermally efficient, quiet, and safe learning environment. Feedback from the site manager highlighted: 'We finished the job faster than expected, with fewer headaches and better results.' This example illustrates how VIPs reduce complexity, lower skill barriers, and deliver significant savings—making them ideal for large-scale public infrastructure projects where efficiency and budget control are paramount.

• Contributing to Low-Carbon Development:
Anhui Lange Litong’s commitment to green innovation was validated in a pilot project at a cold chain warehouse in Zhengzhou, where VIPs were used to insulate a 12,000㎡ refrigerated storage facility. Prior to the upgrade, the facility consumed 1.8 million kWh annually. After switching to VIPs with a thermal conductivity of 0.0028 W/(m·K), energy consumption dropped to 1.2 million kWh—achieving a 33% reduction in annual electricity usage. Over five years, this translates to a cumulative savings of 3 million kWh and a CO₂ emission reduction of nearly 2,400 tons—equivalent to planting over 100,000 trees. The project received recognition from the Ministry of Ecology and Environment as a model for low-carbon logistics infrastructure. Beyond energy savings, Lange Litong is actively researching the integration of recycled glass fibers and bio-based encapsulation materials into their VIP cores, aiming to achieve a 40% reduction in embodied carbon by 2026. Their ongoing R&D efforts, supported by a full-process lab and accelerated aging tests, ensure that every product contributes meaningfully to global decarbonization goals. This case proves that VIPs are not just performance-driven—they are essential tools in the fight against climate change.
