07 Assessment
Advantages
- Exceptional lifespan of 100-200+ years with no maintenance required
- Self-protecting natural patina eliminates need for protective coatings or painting
- 100% recyclable without quality degradation - truly circular material
- Non-combustible (solid sheet) - suitable for all NCC building classifications
- Outstanding corrosion resistance in marine, industrial, and urban atmospheres
- Excellent ductility and formability - can be shaped into complex architectural forms
- Low thermal expansion (40% less than zinc) simplifies detailing
- Antimicrobial properties - naturally inhibits bacterial growth on contact surfaces
Constraints
- Premium cost - significantly more expensive than steel, zinc, or aluminium cladding
- Copper staining - green patina runoff can stain adjacent porous materials (concrete, stone, timber)
- Galvanic corrosion risk when in contact with dissimilar metals (especially aluminium and steel)
- Theft target - high scrap value makes copper vulnerable to theft on construction sites
- Acoustic performance - thin sheet provides minimal sound insulation without backing systems
- Denting susceptibility - softer than steel, prone to hail and impact damage in soft tempers
08 Applications
A1 Standing Seam Roofing Traditional and contemporary copper standing seam roofing for residential, commercial, and institutional buildings, with clips allowing thermal movement
A2 Facade Cladding Panels Cassette, flat-lock, and rainscreen copper panel systems for building facades, available in mill finish or pre-patinated options
A3 Heritage Restoration Replacement and restoration of historic copper roofing, domes, spires, and decorative elements on listed buildings
A4 Gutters and Flashings Custom copper gutters, downpipes, flashings, and weathering details - often paired with other roofing materials
A5 Interior Feature Cladding Copper wall panels, column cladding, and decorative elements for interior architectural applications in hospitality and commercial spaces
