JAMESTOWN, N.Y.—Hope’s Windows, Inc., the nation’s leading name in custom hot-rolled steel and solid bronze window and door systems, highlights its SlightLine175 Series for architectural projects requiring narrow sightlines, expansive glass areas and structural strength. The series combines slender hot-rolled steel profiles with a rigid, fin-like mullion engineered to handle high design pressures while reducing the bulk of framing between windows and doors.
Hope’s SlightLine175 Series features a 2-inch mullion sightline, a 1-7/16-inch fixed-window sightline and a 2-3/16-inch operable sightline. These narrow profiles maximize visible glass and daylight while minimizing interruptions to views, giving architects greater flexibility to create expansive glazed openings without visually heavy framing.
The system pairs a polyimide thermal extrusion with solid hot-rolled steel mullions, creating distinct shadow lines where window and door frames meet. The mullion’s rigid construction provides the structural support needed for large glass facades while maintaining a slim appearance. SlightLine175 also combines the benefits of Hope’s Landmark175 and Jamestown175 Series profiles for operable windows and doors. Window configurations shown in the series’ profile details include fixed, outward-opening casement and projected windows, giving architects options for incorporating operable openings alongside fixed glazing.
Enhances Thermal Performance
Available Thermal Evolution technology enhances thermal performance without sacrificing the slim profile. The technology maintains the inherent strength of solid hot-rolled steel while helping project teams address energy-efficiency requirements, allowing thermal performance and architectural design to work together rather than compete.
The SlightLine175 Series undergoes testing for wind load resistance, impact performance, air infiltration and water penetration. Hope’s reports that the series meets or exceeds applicable industry standards, pairing its minimal framing with performance characteristics that address structural and building-envelope demands.
For durability, SlightLine175 incorporates Hope’s proprietary Power of 5 Finishing System. The process provides protection and longevity, particularly in coastal environments, helping preserve the steel windows and doors against environmental exposure while maintaining their appearance.
Although well suited to contemporary architecture that emphasizes glass and minimal framing, SlightLine175 can be incorporated across architectural styles. Each window and door is custom-made and handcrafted by skilled artisans at Hope’s manufacturing facilities in Jamestown, N.Y., providing flexibility to meet project-specific requirements for shape, size, style and function.
