Application Effect of Insulated Aluminum Roofing in High Temperature Areas

In high temperature areas such as South China, Southwest China, and the Middle East, the insulation performance of building roofs directly determines indoor comfort and energy consumption. The application effect of insulated aluminum roofing in these areas is particularly significant. Measured data shows that under the condition of 40°C outdoor temperature, the inner surface temperature of the roof using Qingliang Plate insulated aluminum roofing is only 32-35°C, while the inner surface temperature of ordinary color steel tile roofs is as high as 55-60°C, with a temperature difference of more than 20°C.

The strong UV radiation in high temperature areas is a severe test for the weather resistance of roofing materials. The fluorocarbon coating of insulated aluminum roofing has excellent UV aging resistance. After 3,000 hours of QUV accelerated aging test, the color difference is less than 3, and the gloss retention rate is greater than 70%, far superior to ordinary polyester coatings. This means that in tropical and subtropical areas, insulated aluminum roofing can maintain appearance quality and protection performance for a long time, without common aging phenomena such as fading and chalking.

For the special needs of high temperature areas, Qingliang Plate has launched an enhanced insulated aluminum roofing product series. This series uses higher density polyurethane core material and high reflectivity cool roof coating, with a solar reflectance index SRI value of more than 85, which can reflect more solar radiation energy back into the atmosphere. In multiple projects in Hainan, Guangdong and other places, enhanced insulated aluminum roofing has helped buildings achieve the goal of near-zero energy consumption roofs, becoming an ideal choice for green buildings in high temperature areas.
