Engineering specifications for hurricane-rated commercial storefront systems. Design pressures from +/-50 to +/-90 PSF based on zone location within Florida's High-Velocity Hurricane Zone.
Commercial glazing systems engineered for Broward County hurricane requirements.
Field-assembled aluminum framing for standard commercial applications.
Factory-assembled panels for faster installation and higher performance.
Four-sided silicone glazing for seamless aesthetic and maximum performance.
Design pressures vary based on location within the building facade.
Within 10% of building dimension from corners. Highest suction pressures due to wind acceleration.
+/-75 to +/-90 PSFAlong roof edges and building perimeter. Moderate pressure increases from field areas.
+/-65 to +/-80 PSFCentral glazing areas away from edges and corners. Standard design pressure requirements.
+/-50 to +/-65 PSFHVHZ requirements by building height and application type.
Frame profiles engineered for HVHZ storefront applications.
Thermally broken aluminum with polyamide strut for energy efficiency and condensation resistance.
Reinforced aluminum with larger thermal break for high-pressure applications and superior performance.
Answers to frequently asked questions about storefront systems in Broward County.
Storefront systems in Broward County HVHZ typically require +/-50 to +/-65 PSF for field glazing and +/-75 to +/-90 PSF for corner zones. Requirements increase based on building height, exposure category, and proximity to building corners.
Zone 5 applies to corner areas within 10% of the building dimension from corners, requiring the highest pressures (+75 to +90 PSF). Zone 4 applies to perimeter/edge areas requiring moderate pressures (+65 to +80 PSF). Field areas have the lowest requirements.
Yes, stick-built storefront systems are allowed in Broward HVHZ but must have Miami-Dade NOA approval and meet required design pressures. Unitized systems are often preferred for higher-pressure applications due to superior structural performance.
HVHZ storefront requires laminated impact glass meeting TAS 201, 202, and 203. Typical makeup is 1/4" glass + 0.090" PVB + 1/4" glass for large missile impact. Larger panels or higher pressures may require thicker glass or SGP interlayer.
