Sliding glass doors in Palm Beach County typically require design pressures of +/-45 to +/-70 PSF depending on location, building height, and exposure category. Coastal areas and upper floors of multi-story buildings require higher ratings. All doors must be designed for 150-170 mph wind speeds.
In the Wind-Borne Debris Region (WBDR) of Palm Beach County, sliding glass doors must be impact-rated per ASTM E1996 or protected by approved hurricane shutters. Areas outside the WBDR may use non-impact doors that meet wind load requirements only.
Standard impact sliding doors can span up to 12 feet wide with 2-3 panels. Pocket sliding door systems with multi-panel configurations can reach 20+ feet of opening. Lift-and-slide systems offer the largest openings up to 24 feet with proper engineering and structural support.
Standard 2-panel impact sliding doors cost $3,500-$7,000 installed. Multi-panel pocket sliding systems range from $8,000-$18,000. Premium lift-and-slide systems with impact glass can cost $15,000-$35,000 or more depending on size, configuration, and finish options.
