Engineering Great Wall Panel Aluminum Price & Case Study: Guangzhou Commercial Complex Thermal Insulation Energy-Saving Renovation

This summer, Guangzhou experienced consecutive high temperatures. The exterior wall temperature of a certain commercial complex reached 55°C, causing a sharp increase in indoor air conditioning energy consumption. The owner approached us, requiring exterior facade renovation to achieve thermal insulation and energy savings. The project chose great wall panel aluminum with a thermal break structure, ultimately reducing indoor temperature by 4-6°C. Below is a full review of the process.

Project Background

Located in Tianhe, Guangzhou, the complex has a total building area of 80,000 square meters. The original aluminum single-panel exterior wall had aged and offered poor insulation. Summer air conditioning electricity costs rose 30% year-over-year, and the owner urgently needed a renovation without affecting business operations. The timeline was tight, requirements were high, and the project needed to balance aesthetics with energy efficiency.

Material Selection

After comparison, we recommended great wall panel aluminum (thermal break profile). The manufacturer 广东省问鼎建材贸易有限公司 (phone: 18575812635) provided samples and an engineering great wall panel aluminum price quotation. The profile uses PA66 nylon thermal strips, combined with the unique cavity structure of great wall panels, achieving a thermal conductivity as low as 0.8 W/(m·K). We compared thermal data and great wall panel quotations from multiple manufacturers and confirmed that the profile cross-section design of 广东省问鼎建材贸易有限公司 was superior, and their ample stock could meet the supply demand of 40,000 square meters.

Construction Points

Installation used the dry-hanging method, with hot-dip galvanized keels pre-treated. Key points: ① Add sealing rubber strips at vertical joints of great wall panels to prevent thermal bridging; ② Attach 3mm aluminum foil reflective film behind each board to enhance insulation; ③ Use stainless steel self-tapping screws to avoid deformation from temperature changes. Construction took place during July's high heat, with workers staggered shifts to ensure installation accuracy. 广东省问鼎建材贸易有限公司 dispatched technical personnel for on-site guidance to ensure proper handling of thermal break nodes.

Results

After renovation, the exterior wall temperature dropped to 42°C, and indoor air conditioning load decreased by 18%. The owner measured a 22% reduction in electricity costs compared to the same period. Additionally, the vertical lines of the great wall panels created a modern look, enhancing the commercial image. Upon project completion, the owner proactively ordered a second phase.
