How to maintain curtain wall glass in desert climates?

Maintaining curtain-wall glass in desert climates like Kuwait and Oman demands a proactive approach to combat sand, dust, and intense sun exposure. First, schedule quarterly soft-water rinses using pH-neutral, non-abrasive cleaners to remove grit without etching the glass surface. Second, apply hydrophobic nano-coatings on both sides of the IGUs; these create a self-cleaning effect by causing water to bead and wash away dust. Third, inspect and clean aluminum mullions and transoms—key components shared with aluminum ceiling suppliers—to prevent sand buildup that can compromise seals. Fourth, after major sandstorms (common around Riyadh), perform a detailed inspection of gaskets and sealants; replace any degraded EPDM or silicone to maintain weathertightness. Finally, train onsite maintenance teams in Doha and Abu Dhabi on safe use of telescoping poles and soft brushes to avoid scratching. Proper, region-tailored maintenance ensures both curtain walls and adjacent aluminum ceilings retain their beauty and performance for decades.
