How suitable are Curtain Wall systems for renovation and retrofit commercial projects

Curtain walls are often an excellent option for renovations and retrofit projects, but suitability depends on structural capacity, existing envelope conditions, budget and program constraints. For full reclad projects, unitized curtain wall systems can speed site work because large panels are pre-fabricated and installed rapidly, minimizing tenant disruption. However, retrofit projects must carefully assess the existing structure for anchorage points, slab-edge tolerances and movement capability; older buildings may require reinforcing or secondary framing brackets to accept new loads. Where full replacement is impractical, hybrid strategies work well—installing curtain wall segments in key elevations, upgrading glazing for improved thermal performance, or applying metal cladding over substrate panels to modernize appearance and add insulation. Thermal performance upgrades are a major retrofit advantage: replacing single-glazed, inefficient façades with double-glazed, low-E curtain walls dramatically reduces energy use and improves occupant comfort. For phased retrofits, stick-built systems with selective panel replacement can be more flexible and economical. Coordination with existing MEP, fenestration details, and fire and smoke containment is essential; ensure continuity of waterproofing and proper integration with parapets, windows and roof lines. Engage façade engineers and an experienced supplier early to produce feasible connection details and a realistic installation plan.
