<h3>The Tropical Roof Challenge</h3><p>Galvanized corrugated metal roofs have long been the standard in Sri Lanka due to initial low costs. However, they present significant performance challenges in tropical coastal environments.</p><h4>How ASA Polymer Works</h4><p>ASA (Acrylonitrile Styrene Acrylate) is an advanced thermoplastic with exceptional UV resistance. Unlike steel which conducts heat directly into your home, the multi-layer polymer structure of i-Roof sheets creates a thermal barrier.</p><p>Independent laboratory tests show that ASA polymer sheets can reduce roof surface temperature by up to 15°C compared to dark-colored steel sheets under the same solar exposure.</p>
