Casement windows in Miami-Dade HVHZ typically require design pressures of +/-50 to +/-70 PSF depending on building height, location, and exposure category. All units must have impact-rated laminated glazing and a valid Miami-Dade NOA.
Yes, casement windows are excellent for hurricane areas when properly specified. Their compression seal design creates a tighter seal under wind pressure, and the multi-point locking hardware provides superior structural performance compared to sliding windows.
Maximum sizes vary by manufacturer and design pressure. Single casement windows typically max out at 36" wide x 72" tall for high design pressures. French casement pairs can span up to 64-72" wide total with appropriate ratings.
Yes, HVHZ-rated casement windows require multi-point locking hardware (typically 3-5 lock points), heavy-duty hinges rated for the design pressure, and often require positive-pressure locking mechanisms that engage automatically when closed.
