How long is the lifespan of a properly installed curtain wall system?

A properly designed and installed metal-glass curtain wall can function effectively for several decades, typically providing 25 to 40 years of service under normal conditions and even longer with diligent maintenance. Lifespan depends on materials (anodized vs PVDF coatings), environmental exposure (coastal salt vs inland desert), and maintenance practices. In Gulf regions, more aggressive coastal or sand exposure may accelerate wear on sealants, gaskets and finishes, making scheduled replacement of consumables an important part of lifecycle planning. Key longevity drivers include high-quality IGU edge seals, warm-edge spacer choices, corrosion-resistant anchorages and finishes, and thermally stable frame assemblies. Regular maintenance cycles—cleaning, gasket replacement, resealing perimeters and inspecting drainage—can extend service life toward the higher end of the range. Additionally, modular unitized systems facilitate replacement of damaged panels with minimal disruption, preserving life-cycle value. When we manufacture and supply curtain walls, we provide as-built documentation, tested component lifetimes, and recommended maintenance intervals so owners in Dubai, Abu Dhabi, Riyadh and Doha can budget for mid-life renewal of sealants or gaskets rather than wholesale replacement — ensuring predictable performance and lifecycle costs.
