How durable are glass wall curtains in extreme climates such as coastal or desert environments?

Durability of glass wall curtains in extreme coastal or desert climates depends on material selection, protective finishes and maintenance regimes. Coastal environments—Dubai, Doha, Baku—expose façades to salt-laden air that accelerates corrosion in metal components. Desert climates subject façades to high solar irradiance, thermal cycling and abrasive dust. To achieve long service life, specify corrosion-resistant metal systems, appropriate glass coatings, and robust sealing strategies.

Aluminum framing with high-quality anodized or AAMA 2604/2605 powder coatings offers good corrosion resistance; for severe marine exposure, consider stainless steel anchors or duplex systems (stainless steel fasteners with coated aluminum extrusions). Metal alloys and surface treatments should be selected per exposure class; in severe chloride environments, protective gasketing, sacrificial drainage pathways and regular wash-down schedules reduce salt accumulation. For desert conditions in Riyadh or Muscat, glazing should use low-E coatings to reduce solar heat gain and tempered or laminated glass to resist thermal stress and sand impact.

Sealant selection is critical: UV-resistant, elastomeric silicone or polyurethane sealants rated for high temperatures ensure long-term elasticity. Thermal movement joints must accommodate expansion without compromising water-tightness. For mixed continental climates in Central Asia (Kazakhstan, Kyrgyzstan), account for freeze-thaw cycles and select warm-edge spacers and desiccants to prevent condensation and seal failure.

Long-term durability is supported by manufacturer warranties, third-party testing and an agreed maintenance plan. Regular inspections, cleaning schedules adapted to local conditions and timely replacement of weather seals will preserve performance and appearance of glass wall curtains in extreme climates.
