What maintenance requirements should facility managers expect for a commercial Curtain Wall System?

Facility managers overseeing metal curtain walls—common across the Middle East and Central Asia—should expect a structured preventive maintenance program to protect performance, appearance, and warranty compliance. Routine tasks include scheduled exterior cleaning to remove salt, dust, and pollutants that accelerate finish degradation; in coastal Dubai or Kuwait this often means more frequent wash cycles. Inspect seals, gaskets, and sealants at least annually; look for UV-induced cracking, adhesion loss, or compression set in EPDM or silicone gaskets. Replace failed or aged sealants and secondary gaskets to maintain air and water resistance. Check drainage channels and weep holes quarterly to prevent blockages from sand or debris; pressure-equalized systems require particular attention to ensure balanced pressure and avoid leakage. Monitor fasteners and anchors for corrosion or loosening, particularly stainless steel screws in salt-exposed environments; document torque checks during scheduled maintenance. Glazing should be inspected for edge seal degradation and glass breakage; laminated glazing may require inspection for delamination or moisture ingress. For thermal break systems, verify that insulative spacers remain intact and that seal continuity at thermal junctions is maintained. Maintain records of all inspections, repairs, and materials used—this log supports warranty claims and lifecycle planning. For buildings intending LEED or local green certification in Almaty, Astana, or Doha, maintain HVAC interactions by ensuring façade air tightness is preserved. Finally, engage qualified façade maintenance contractors for high-rise access and testing, and plan for mid-life refurbishment—recoating or selective component replacement—every 15–25 years depending on environmental exposure.
