High-rise buildings in Palm Beach County experience increased wind pressures at elevation. Design pressures can exceed +/-100 PSF on upper floors of tall buildings, compared to +/-50 PSF at ground level. All glazing must meet FBC requirements including impact rating in WBDR areas.
Wind pressures increase significantly above 60 feet. Buildings over 4 stories typically require enhanced glazing systems. The most critical wind pressures occur in the upper 20% of the building height and at corners where pressures can be 50% higher than at center wall locations.
High-rise buildings use three main systems: punch windows installed in concrete or masonry wall openings, stick-built curtain walls assembled on-site piece by piece, and unitized curtain walls pre-fabricated in a factory. Unitized systems dominate new construction for quality control and installation speed.
Punch window systems cost $75-120 per square foot installed. Stick curtain wall systems range $100-175/SF. Unitized curtain wall systems cost $150-275/SF. Total glazing packages for high-rise towers can range from $2-10 million depending on building size and specifications.
