What factors affect curtain wall system lifespan?

Several factors govern the lifespan of curtain-wall systems in arid Gulf climates—critical for projects in Qatar or Bahrain. Material selection tops the list: high‐performance aluminum alloys with PVDF or anodized finishes resist corrosion and UV degradation. Glass quality—laminated vs. tempered—affects resistance to thermal cycling and sand abrasion. Sealant choice (silicone vs. polyurethane) and gasket material (EPDM vs. neoprene) determine weather tightness over decades. Installation precision—particularly alignment of mullions and transoms—prevents stress concentrations that can crack sealants. Finally, regular maintenance: semiannual cleaning, gasket inspections after dust storms, and resealing every 5–7 years extend service life beyond 30 years. Synchronizing curtain-wall upkeep with aluminum ceiling maintenance ensures total building-envelope performance remains optimal.
