The Aged Beauty of Copper Aluminium Sheets in Building Facades

Vijay Raj23 Jan, 2024Business

The copper aluminium sheet is a composite building material whose top layer is Copper and the bottom layer is Aluminium. The combination of Copper and Aluminium along with a thin thermoplastic core for the non-fire retardant panel, and a mineral core for the fire-retardant panel, makes it the choice for interior and exterior wall Copper cladding, column cladding and retail branding. Being exposed to rain, sunshine, and humidity causes weathering of the panels known as Patina, this causes the layer to change colour dynamically throughout the process. The formation of a patina takes years, and with time the colour of copper changes, adding a fresh new colour in every phase. Copper-aluminum sheets begin with a reddish-brown shade, sometimes tinged with silver. As time passes, the Copper cladding acquires a green patina, that not only enhances their aesthetics but also fortifies their durability.
