Performance of Insulated Aluminum Roof Tiles in High-Temperature Regions

In high-temperature regions across southern and southwestern China, the Middle East, and beyond, a building's roof insulation directly impacts indoor comfort and energy consumption. Insulated aluminum tiles deliver exceptional performance in these areas. Field data shows that under an outdoor temperature of 40°C, using...Cool BoardThe inner surface temperature of the insulated aluminum tile roof ranges only from 32°C to 35°C, while that of a standard color steel tile roof reaches as high as 55°C to 60°C—a temperature difference exceeding 20°C.

Intense UV radiation in hot climates poses a severe challenge to the weather resistance of roofing materials. The fluorocarbon coating on our heat-insulating aluminum tiles offers superior UV aging resistance. After 3000 hours of QUV accelerated aging testing, color change is less than 3, and gloss retention exceeds 70%, far outperforming standard polyester coatings. This ensures that in tropical and subtropical regions, our heat-insulating aluminum tiles maintain their appearance and protective performance over time, avoiding common aging issues such as fading or chalking.

Designed for extreme heat, Cool Roof Panels introduces an Enhanced Insulated Aluminum Shingle series. Featuring high-density polyurethane core and high-reflectance cool roof coatings, this series achieves a Solar Reflectance Index (SRI) of 85 or higher, reflecting more solar radiation back into the atmosphere. In projects across Hainan, Guangdong, and other hot regions, these shingles have helped buildings reach near-zero energy roofing targets, making them the ideal choice for green construction in high-temperature climates.
