The superior thermal properties of aluminum are critical for buildings aiming for energy efficiency under the equatorial sun. Aluminum is a highly reflective metal, possessing a high solar reflectance index (SRI). This means that it reflects a significant proportion of incident solar radiation away from the roof's surface, minimizing the heat gain transmitted into the building envelop... https://kkroofspecialist.com.sg/aluminum-roofing-material-singapore/
