Choosing the right curtain wall system requires evaluating several project-specific factors:
**1. Building height and location:**
- Low-rise (1-5 floors): Stick system or window wall may suffice
- Mid-rise (6-20 floors): Unitized or stick system depending on schedule
- High-rise (20+ floors): Unitized system recommended for quality control and installation speed
- Coastal/high-wind zones: Enhanced wind load and corrosion resistance required
**2. Project scale and repetition:**
- Large, repetitive facades → Unitized system (factory efficiency)
- Small or irregular facades → Stick system (flexibility)
- Mixed geometry → Hybrid approach
**3. Budget and timeline:**
- Fast-track projects → Unitized (parallel manufacturing and site prep)
- Budget-constrained → Stick system (lower upfront cost)
- Long-term value → Invest in thermal break + Low-E glass for energy savings
**4. Performance requirements:**
- Energy codes → Thermally-broken profiles, high-performance IGUs
- Acoustic needs → Laminated glass, varying cavity widths
- Seismic zones → Movement joints, laminated glass
- Fire safety → Fire-rated systems at property lines
**5. Maintenance access:**
- Consider cleaning access, glass replacement logistics, and sealant maintenance intervals
**6. Supplier capabilities:**
- Manufacturing capacity and quality systems
- Engineering support for design development
- Project management and installation guidance
- Export experience and international certifications
