Material
Zinc
Zinc is a naturally occurring metal used in building envelopes for roofing, façade cladding, and rainwater systems, valued for its durability and recyclability. VMZINC and similar manufacturers provide comprehensive Environmental Product Declarations following ISO 14025 and EN 15804 standards, documenting lifecycle impacts across extraction, processing, use over 100 years, maintenance, and disposal.
Zinc sheets and coils serve as self-supporting or fully supported metal systems for roof and façade applications in civic, cultural, and public buildings, often complementing glass and stone materials. The material is CE-marked under EN14782 and EN14783 standards and generates minimal waste during installation, with less than 5% scrap that is 100% recyclable.
Zinc production and processing carry embodied carbon impacts documented in manufacturer EPDs, though lifecycle analyses account for the material's 100-year service life and full recyclability, which offset initial environmental costs. Post-consumer recycled content typically ranges from 21% to 33% pre-consumer recycled material, reducing but not eliminating upstream extraction impacts.
