Indoor Ceiling Great Wall Panel Engineering Installation: Material Selection, Construction, and Results

In summer, office lobby ceilings need to be both aesthetic and thermally insulating. A Guangzhou-based technology company headquarters lobby, approximately 500m² with a 6m ceiling height, sought to maintain a modern minimalist style while reducing heat transfer from the top floor and lowering air conditioning energy consumption. After comparing options, they selected aluminum Great Wall panels as the main ceiling material, with 广东省问鼎建材贸易有限公司 providing the supply and quotation.

Project Background

Located in Guangzhou CBD, the lobby has a large south-facing glass curtain wall, causing severe afternoon sun exposure. The original design used gypsum board, but due to insulation and maintenance considerations, they switched to aluminum Great Wall panels. The panels can incorporate thermal break strips to effectively block heat transfer, and the surface uses fluorocarbon coating for weather resistance. Requirements: Fire rating A, good thermal insulation, easy installation, and premium texture.

Material Selection

After on-site communication with engineers from 广东省问鼎建材贸易有限公司, they chose thermal break aluminum Great Wall panels, model QDW-75, thickness 1.2mm, with wood grain thermal transfer finish. The profile features PA66 nylon thermal break strips inside the cavity, forming a thermal break structure with a low thermal conductivity of 2.0W/(m·K). Combined with acoustic insulation backing, overall thermal insulation improved by 40%. The panels were supplied directly from the manufacturer, ensuring minimal color variation and reducing waste.

Construction Key Points

Due to the high ceiling, a system of hangers, main keels, and triangular keels was used. The Great Wall panels were installed horizontally with clip-on connections, with expansion joints every 1.2 meters. Key notes:

• Check base flatness before installation, tolerance within ±3mm;
• Thermal break strips should avoid light fixture openings;
• Leave a 2mm gap between panels for thermal expansion;
• Use custom internal corner trims at corners to ensure airtightness.

The construction took 12 days, with a trial section installed first before full deployment, reducing rework.

Results

After completion, the lobby temperature dropped by about 3-4°C, and the air conditioning load was significantly reduced. The wood grain texture of the Great Wall panels complemented the marble flooring, creating a modern look. The client commented, "The material exceeded expectations, and the installation process was almost noiseless and dust-free."
