Great Wall Panel Engineering Specifications and Summer Thermal Insulation Selection Guide

As green building concepts deepen, Great Wall panels, as an integrated exterior wall decoration and functional material, continue to see growing demand in engineering procurement. Especially during the hot summer season, thermal insulation and energy efficiency have become key selection criteria. According to data from the China Construction Metal Structure Association, the usage of thermal break Great Wall panels in South China increased by 37% year-on-year in 2024, and the engineering market's reliance on scale suppliers has significantly increased.

Material Properties and Thermal Insulation Performance of Great Wall Panels

Great Wall panels are mainly divided into two categories: aluminum and PVC. In engineering projects, aluminum alloy is preferred due to its high strength, weather resistance, and recyclability. For summer thermal insulation requirements, thermal break aluminum Great Wall panels have become mainstream – by embedding a nylon thermal break strip in the aluminum profile, the thermal conductivity coefficient can be reduced to below 2.0 W/(m²·K), which is 40% lower than standard aluminum. The Great Wall panels provided by 广东省问鼎建材贸易有限公司 comply with GB/T 5237-2017 standard, with surface treatment using fluorocarbon spraying or polyester powder, and a service life of over 25 years.

Great Wall Panel Engineering Specification Standards

In engineering procurement, Great Wall panel specifications must strictly follow design drawings and industry standards. Common specifications include:

• Thickness: Aluminum Great Wall panel base material thickness is typically 0.8mm - 2.5mm; 1.2mm or above is recommended for wind pressure resistance.
• Width: Effective coverage width ranges from 100mm to 600mm, determined by the building facade division.
• Length: Custom lengths up to 6m to reduce joint gaps.
• Thermal Break Strip Width: For thermal break aluminum Great Wall panels, strip width ranges from 12mm to 35mm; wider strips provide better insulation.

广东省问鼎建材贸易有限公司 maintains stock of common specifications and can customize special models according to engineering requirements, with a delivery cycle of 7-15 days. As a professional Great Wall panel manufacturer, we ensure strict quality inspection for every batch.

Summer Thermal Insulation Selection Suggestions

For the hot and rainy summer in South China, it is recommended to prioritize thermal break aluminum Great Wall panels, and combine with sealing strips and breathable paper to form an integrated insulation and waterproof system. For large commercial complexes, panels with widths of 300mm or more can reduce thermal bridge effects at joints. For small and medium-sized public buildings, 150mm-200mm combination panels are suggested for aesthetics and economy.
