What maintenance requirements do glass wall curtains have over long-term commercial building use?

A proactive maintenance program ensures glass wall curtains retain performance, aesthetics and safety over their lifecycle. Key maintenance areas include regular cleaning of glazing and metal surfaces, inspection and replacement of weather seals, monitoring of anchor bolts and drainage channels, and periodic testing for water and air tightness. In the Middle East and Central Asia, environmental factors—salt spray, dust storms, and temperature extremes—require tailored maintenance frequencies: coastal façades need more frequent wash-downs; desert sites benefit from dust mitigation rounds after sand events.

Inspection schedule: perform visual inspections quarterly, including checks for sealant cracks, gasket compression loss, glass edge chips, and any sign of corrosion on metal anchors. Annual technical inspections should measure unit deflection, check adjustable anchors for torque, and verify that drainage weeps are free. Every 5–10 years, consider a full façade condition survey by the manufacturer or third-party façade engineer to plan medium-term remediation.

Cleaning: use approved detergents and low-abrasion methods to avoid damaging coatings. Avoid high-pressure washing near seals; instead, use soft brushes and controlled rinsing. Replace sealants and EPDM gaskets when elasticity declines or after visible degradation—timely replacement prevents water ingress and secondary corrosion.

Record keeping: maintain a façade maintenance log with inspection reports, photos, repair records and material batch numbers. For projects in Kazakhstan, Uzbekistan or Turkmenistan, clearly document local supply sources for replacement seals and metal profiles to avoid procurement delays. A structured maintenance contract with the façade supplier ensures access to approved materials and preserves warranties, optimizing lifecycle cost and façade longevity.
