Data-driven comparison of aluminum, steel, and structural glazing systems for Miami-Dade HVHZ compliance. Make informed decisions with side-by-side performance metrics.
Side-by-side specifications for HVHZ-compliant storefront systems.
Most common choice
Maximum strength
Premium frameless
For most commercial applications in HVHZ, aluminum storefront systems offer the best balance of cost, performance, and availability. Steel systems are preferred for high-security needs or extreme spans, while structural glazing suits premium architectural projects where aesthetics are paramount.
Yes. All storefront systems installed in Miami-Dade HVHZ must have a valid Notice of Acceptance (NOA) from Miami-Dade County Product Control. Systems with only Florida Product Approval are not sufficient for HVHZ areas. Structural glazing may require project-specific engineering approval.
Storefront systems in Miami-Dade HVHZ must be designed for 180+ mph wind speeds. The actual design pressure depends on building height, exposure category, and internal pressure classification. Typical design pressures range from ±50 PSF to ±90 PSF for commercial applications.
Aluminum storefront systems range from $45-75/SF installed. Steel systems cost $85-120/SF due to material and fabrication costs. Structural glazing systems range from $120-200/SF for the frameless aesthetic and complex engineering required.
