IndiaWILLSTRONG® CCP
Copper Composite Panel
WILLSTRONG® Copper Composite Panel (CCP) integrates the rich, evolving luster of authentic copper with the structural stability of a mineral-filled core. As time progresses, the copper surface gracefully matures from raw metallic sheen to warm dark brown, eventually forming a distinctive green patina that provides natural, lifelong protection against environmental corrosion.
Designed for high-end monumental architecture, luxury residential façades, and premium roof cladding, CCP offers unrivaled elegance, absolute surface flatness, and effortless processing without the prohibitive weight and cost of solid copper sheets.
Copper Composite Panel's authentic copper surface forms a protective patina, offering self-healing corrosion resistance and evolving aesthetics for decades.
With A2 mineral core, CCP provides high flexural strength and flatness, eliminating oil-canning and distortion typical of thin copper.
Copper composite panel uses a high-grade copper skin and a B1 flame-retardant advanced mineral core with effective smoke suppressant additives.
The panel gives excellent overall flatness, structural rigidity, sound insulation, and also B1 self-extinguishing properties with very low smoke emissions.
Copper composite panel is made of a thin copper layer and a lightweight polyethylene core that is also highly flexible.
It provides overall good flatness, also effective sound damping, adequate structural strength, and very low maintenance with long-lasting visual appeal.
