As a common roofing material, the thermal insulation performance of PVC roofing tiles is influenced by factors such as thickness, color, and structural design. Due to their low thermal conductivity, they can effectively slow down the transfer of heat into the interior, but they cannot prevent the temperature from rising. Light-colored PVC roofing tiles reflect sunlight more effectively and provide better thermal insulation than dark-colored tiles. Double-layered PVC roofing tiles or those with an air gap provide better thermal insulation. When selecting roofing tiles, priority should be given to light-colored or highly reflective options...
