Can a curtain wall system resist sandstorms effectively?

Curtain walls in desert hubs like Kuwait City and Abu Dhabi face frequent sandstorms that can abrade glass and clog seals. Effective resistance hinges on three key design elements. First, choose laminated or tempered glass with surface hardness ≥6 Mohs; this prevents long‐term etching. Second, specify EPDM or silicone gaskets rated for abrasion and UV; dual‐lipped seals at mullion‐to‐glass interfaces create tortuous paths for sand infiltration. Third, incorporate pressure‐equalized rain-screen cavities: by balancing internal and external air pressure, the system prevents sand ingress during sudden gusts. Regular maintenance schedules—coordinated with aluminum ceiling cleanings—ensure debris is cleared from weep holes and drainage channels. Additionally, integrating architectural metal fins at known windward façades (common in Riyadh) functions as sacrificial shields, protecting glazing. These strategies guarantee curtain walls—and adjoining aluminum ceilings—remain functional and visually pristine even after severe desert storms.
