Copper-Aluminum Door FAQs
How does a copper-aluminum door compare to traditional wooden doors?
Copper-aluminum doors offer superior durability with 3-5 times longer lifespan than wood, require no regular maintenance like painting or sealing, and provide better insulation properties. The metal composite structure makes them highly resistant to warping, cracking, or rotting that affects wooden doors over time.
What maintenance does a copper-aluminum door require?
Our copper-aluminum doors require minimal maintenance - occasional cleaning with mild soap and water is sufficient. The powder-coated finish resists fading, and unlike pure copper, the alloy won't develop a green patina unless specifically requested. No periodic sealing or repainting is needed.
Are copper-aluminum doors energy efficient?
Yes, our copper-aluminum doors feature thermal break technology that exceeds most building codes. The polyamide barrier between inner and outer metal layers prevents thermal transfer, achieving U-values as low as 0.8 W/(m²K). This can significantly reduce heating and cooling costs compared to standard metal doors.
Certifications and Standards

Additional Copper-Aluminum Door Questions
How fire-resistant are copper-aluminum doors?
Our standard copper-aluminum doors achieve 60 minutes of fire resistance (EI60 classification). For higher requirements, we offer specialized fire-rated versions that meet EI90 and EI120 standards, certified according to EN 1634-1. The metal construction naturally resists fire spread compared to combustible materials.
Can copper-aluminum doors be installed in coastal areas?
Absolutely. The copper-aluminum alloy provides exceptional salt spray resistance, outperforming standard aluminum in marine environments. We recommend our marine-grade hardware packages (316L stainless steel) for coastal installations, along with additional drainage features to handle high humidity and salt exposure.
What's the lead time for custom copper-aluminum doors?
Standard sizes ship within 4-6 weeks. Custom designs typically require 8-10 weeks for production, including 2 weeks for engineering review. Express 4-week production is available for urgent projects with simple configurations. All doors undergo rigorous quality control before shipment.
