Architectural UV Stability: Why Natural Stone Outperforms Faux Stone in High-Exposure Projects
UV stability is a critical determinant of long-term asset value for exterior facades. This technical report details the chemical superiority of natural mineral pigments over synthetic dyes, explaining how inorganic atomic bonds withstand high-energy photon bombardment. We evaluate advanced testing protocols, including Xenon Arc (ASTM G155), and provide a regional performance analysis for high-UV zones like the UAE and Australia. For B2B stakeholders, the guide demonstrates how specifying natural stone reduces life-cycle maintenance costs by eliminating the “graying” and structural embrittlement common in manufactured faux stone.
