Just weeks after Marvin discontinued its Coastline Collection, Hope's Windows announced Florida Building Code certification—including HVHZ—for its Old World Suite steel and bronze systems. For architects designing to Miami-Dade, the ultra-luxury heritage aesthetic is back on the table.
A Well-Timed Certification
On July 21, 2026, Hope's Windows announced that its Old World Suite products are now tested and certified to meet the Florida Building Code (FBC), including the High Velocity Hurricane Zone (HVHZ). The Old World Suite line has undergone testing to meet the demands of Florida's hurricane-prone regions, with certification covering wind load resistance, impact performance, air infiltration, and water penetration.
The timing matters. With Marvin's Coastline Collection recently discontinued in HVHZ counties, architects designing high-end coastal residences in South Florida have been scrambling to fill a specification gap in the premium, thin-profile window category. Hope's—a Jamestown, New York, manufacturer of custom hot-rolled steel and solid bronze systems—just walked into that gap with a heritage aesthetic that vinyl and standard aluminum products cannot replicate.
What's Actually Certified
The Old World Suite is not a new product line, but the HVHZ certification is a meaningful expansion of where it can be legally specified. Hope's positions the Old World Suite as an ultra-luxury line of hot-rolled steel and solid bronze window and door systems handcrafted in Western New York, combining aesthetics, strength, and performance.
Key technical points for spec writers:
- Certification scope: Florida Building Code, including HVHZ (Miami-Dade and Broward counties)
- Tested performance criteria: wind load resistance, impact performance, air infiltration, water penetration
- Profile characteristics: Fabricated from solid hot-rolled steel profiles, the Old World Suite is engineered to withstand extreme weather while providing ultra-slim sightlines, with proprietary profiles that are fully welded, hot-dip galvanized, and factory finished for coastal protection.
- Design pressures: Maximum sizes and design pressures were developed and tested to satisfy the latest industry trends.
The Old World Suite sits alongside other Hope's HVHZ-rated products including the Jamestown175 and Landmark175 series and the Empire Bronze variants. The Old World Suite's classic coped three-point profile allows casement windows to achieve hurricane and impact ratings, joining a broader Hope's HVHZ portfolio that meets IBC, IRC, FBC, and Miami-Dade County standards.
Why This Matters for Coastal Luxury Specs
South Florida's ultra-luxury residential market has always had a specification problem: HVHZ code demands large-missile impact resistance and structural performance that historically forced designers into thicker aluminum profiles or specialty impact laminated IGUs housed in bulky frames. That is fine for modern glass boxes on Fisher Island; it is a problem for the growing pipeline of Mediterranean, Georgian, and pre-war-inspired estates where slim, black, gridded steel or bronze profiles are the entire design language.
For architects and specifiers, the practical implications are:
- HVHZ-compliant heritage aesthetic: The steel casement profile can now be spec'd in Miami-Dade and Broward without variance requests or engineered exceptions.
- Documented performance envelope: Design pressures and maximum tested sizes give structural engineers a starting point for wind-load calculations rather than custom testing programs.
- Domestic manufacturing: Hope's produces its bespoke steel and bronze windows and doors domestically in its Jamestown, New York, manufacturing facilities, which matters for developers navigating current Section 232 aluminum and steel tariff volatility on imported specialty windows from European heritage brands.
The Competitive Picture
With Marvin exiting Coastline and Andersen focused on the volume premium market, the certified HVHZ steel-window field narrows to a short list dominated by heritage-focused specialists. Hope's, Optimum Window, Crittall (via importer channels), and a handful of European brands like Steel Windows & Doors compete for what is effectively a custom-fabrication market. HVHZ certification is the ticket to entry, and it is expensive to obtain and maintain—each product line requires its own suite of TAS 201/202/203 testing.
For general contractors and building envelope consultants, the operational takeaways:
- Lead times remain long. Custom hot-rolled steel is not a stock product; expect procurement timelines measured in months, not weeks, and build float into the schedule.
- Coordination with structural engineers is non-negotiable. Even with certified maximum sizes, the interface between HVHZ-rated steel windows and CMU or concrete openings requires specific anchor detailing.
- Thermal performance is a separate conversation. HVHZ certification addresses structural and impact performance, not U-factor. Projects chasing both hurricane compliance and Florida's tightening energy code need to confirm insulated glass configurations independently.
For a market that just lost one of its most-specified premium coastal window lines, Hope's HVHZ certification of the Old World Suite is a rare piece of good news on the South Florida spec sheet.
