Short Answer
Few operable wall systems meet 200 MPH wind load performance. DoorWall Systems’ Arc3D Duo™ and Solo achieve a 200 MPH static closed wind rating and 110 MPH operating wind rating, making this DoorWall product the highest-performing architectural operable walls available.
Expanded Insight
High-wind environments demand engineering beyond typical commercial door construction. The Duo and Solo incorporate reinforced thermally broken aluminum frames and section profiles, combined with an available extending mechanical lateral sealing system, laminated insulated heat-strengthened safety glass, and a self-supporting system structure that transfers load downward rather than onto the surrounding structure.
Their performance is validated through ASTM E330 structural testing, ensuring panel deflection, frame reinforcement, and glazing retention meet strict criteria for extreme environments. These systems are often selected for coastal, high-rise, or high-exposure sites where large glazed openings must remain both operational and structurally secure.
For architects, the ability to specify an operable wall that combines architectural finish quality with hurricane-class wind performance eliminates the compromise traditionally found between aesthetic and structural needs.
