Environmental sustainability of vitreous enamel coatings in architectural application

This study evaluates the feasibility of vitreous enamel coatings for architectural facades, analyzing enameled steel, aluminum, and composite panels in terms of durability, recyclability, and environmental resistance. The behavior of the enameled panel is compared with the most commonly used solutions such as painted panels. The research examines production processes, material properties, market dynamics, and environmental impact to assess performance and sustainability. Special attention is given to raw material sourcing, lifecycle analysis, and compliance with environmental regulations. Additionally, production technologies, logistics, and end-of-life scenarios, including recycling strategies, are explored to address sustainability challenges associated with enamel coatings. Enameled panels, despite higher initial costs, prove more sustainable and economically viable over their lifecycle than painted alternatives, thanks to superior durability, corrosion resistance, low maintenance, fire and UV resistance, and long-term aesthetic stability. • Enamel layers exhibit excellent durability and long-term aesthetic stability. • Sustainability in building materials is becoming increasingly relevant. • The evaluation of CO 2 emissions and energy consumption is essential.
