What risks should project owners assess when specifying a high-performance curtain wall system?

Specifying a high-performance metal curtain wall system carries benefits and risks owners must evaluate to protect schedule, cost, and long-term performance. Technical risk centers on unvalidated performance claims—require independent test data for thermal, air, and water performance, and demand full-scale mock-ups to confirm real-world behavior. Supply-chain risk includes single-source dependencies for proprietary systems; evaluate supplier capacity, fabrication lead times, and local logistics to avoid delays.

Interface risk is common: curtain wall systems connect to structure, floors, and services. Poor detailing can cause tolerancing conflicts, water ingress, or thermal bridging. Ensure early coordination between façade engineers, structural engineers, and MEP teams. Warranty and maintenance risk should be quantified: premium finishes and special finishes may require bespoke maintenance programs—confirm lifecycle cost estimates and access for replacements. For tall buildings, access systems for cleaning and façade maintenance must be considered in the early design stage.

Finally, regulatory and site-specific environmental risk—exposure to coastal salts, industrial pollutants, or seismic conditions—should inform material and anchorage choices. Mitigation strategies include robust mock-ups, staged procurement reviews, conservative design margins, and performance bonds.
