How does a curtain wall system perform in high-wind, seismic, and extreme climate conditions?

A metal curtain wall system’s performance under high-wind, seismic and extreme climate conditions depends on engineered design, material selection, connection detailing and quality-controlled fabrication. For projects across the Middle East and Central Asia — from coastal Abu Dhabi to inland Riyadh and into Kazakhstan or Uzbekistan urban centers — our metal curtain wall products are engineered with specific wind-load and seismic-response criteria in mind. Structural engineers evaluate site-specific wind speeds, gust factors, seismic zone classifications and façade overturning effects, then translate these into a curtain wall system design that includes reinforced mullions, deeper transoms, moment-capable anchors, and flexible thermal isolation joints to accommodate differential movement. For metal façades we select high-strength aluminum alloys and stainless-steel anchors with proven fatigue resistance; for coastal or desert environments we specify protective finishes and powder coat systems with additional pretreatment to resist corrosion from salt-laden air or sand abrasion. Seismic detailing focuses on allowing controlled drift between the primary structure and the curtain wall through sliding anchors, slotted connections, and isolation seals that retain water-tightness while permitting movement. Pressure-equalized venting strategies, robust gaskets, and pressure-tested glazing units are used to prevent glass breakage and water ingress during gust events. Testing to relevant standards (ASTM, EN, AAMA, and regional codes) and mock-up load tests validate performance prior to mass production. In summary, when specified and fabricated by experienced metal curtain wall manufacturers, a curtain wall system can reliably withstand extreme wind and seismic forces across Middle East and Central Asian project conditions, provided the design integrates local climate data, structural input, and field-proven detailing.
