PRANCE metalwork is a leading manufacturer of metal ceiling and facade systems.
What installation challenges should contractors expect when specifying glass wall curtains for large façades?
Contractors installing large glass wall curtain façades should anticipate logistical, tolerancing, and interface challenges that stem from scale, site conditions and the hybrid nature of glass and metal systems. Major concerns include precise alignment of metal mullions, handling and sequencing of heavy glass units, differential tolerance management between structural frames and curtain modules, and ensuring water/air-tightness at scale. In densely built Middle East cities—Dubai, Doha, Abu Dhabi—or Central Asian projects in Tashkent or Almaty, crane access, staging zones and dust control become critical operational constraints affecting schedule and safety.
Tolerances in building structure must be assessed before façade installation: concrete slab edge flatness and column plumbness deviations should be measured and corrected with shims, packers and adjustable anchors. Metal framing systems often include slotted anchorage or adjustable cleats to accommodate these deviations; however, installers must be trained in torque control, sequence setting and alignment checks to keep panel gaps uniform and prevent glass edge loading.
Handling logistics: glass panels and metal frames require protective transport dunnage, vacuum lifters and qualified rigging crews. Thermal expansion considerations in hot climates necessitate movement joints and proper sealing; adhesive curing times and sealant selection must match ambient temperatures. Mock-up assembly on-site and factory pre-assembly reduce rework and verify installation methods. Interface coordination with trades—window washing systems, shading devices, and MEP penetrations—must be finalized prior to sealing.
Quality control: implement a tested QC checklist with dimensional surveys, anchorage torque records, and water infiltration testing. For projects in Kazakhstan, Turkmenistan, or Kyrgyzstan, account for cold-start installation protocols and sealant temperature constraints. Effective planning, specialized crews, and rigorous site supervision will mitigate installation risks and deliver durable, high-performance glass wall curtain façades.
