What Is the Lifespan of an Aluminum Curtain Wall Installed on a Commercial High-Rise?

The service life of an aluminum curtain wall varies with design, material quality, environmental exposure and maintenance, but well-specified systems commonly provide 25 to 50+ years of reliable performance. Key determinants of lifespan include the quality of aluminum extrusions (alloy grade and temper), finish selection (anodized or PVDF coatings), type of glazing and sealants, and corrosion-resistant fasteners. In harsh climates such as the Gulf—where UV, heat and salt can accelerate degradation—premium PVDF finishes and rigorous installation practices lengthen life. In continental Central Asian climates, thermal cycling and freeze-thaw exposure demand resilient gaskets and properly detailed thermal breaks to prevent long-term deterioration. Routine maintenance—periodic inspection, sealant replacement, cleaning to remove salts or pollutants, and repair of localized damage—has a large impact on longevity. Manufacturer warranties often cover finishes and components for 10–20 years, but proactive asset management can extend functional life beyond warranty periods. For owners in Dubai, Doha, Almaty or Tashkent, planning for lifecycle costs, specifying test-backed components and establishing a maintenance program are the surest ways to achieve long-term value from aluminum curtain-wall investments.
