Half-Circle Arched Window – Kolbe Ultra Series Garden-Aire

Featuring a semicircular profile, this half-circle arched transom window is a Revit family developed with layered extruded framing and glazed infill. Defined by its true half-round geometry, the unit features a curved outer perimeter anchored to a level bottom rail and integrated sill. Concentric extrusion offsets delineate the exterior cladding profile, the intermediate sash frame, and the internal glass perimeter. Finished with a neutral perimeter trim and a crisp internal sash rebate, the assembly accurately reproduces the layered depth and shadow lines typical of high-performance composite fenestration. The glazed centre panel sits flush within the sash rebate to provide a clean glazed opening that balances classic arched proportions with precise detailing.

The download is a 573 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Architects can load this RFA component into native Revit project environments to insert it as a wall-hosted window family. The component integrates into standard exterior wall constructions and aligns cleanly above door openings. In elevation and section views, the clean perimeter profiles generate accurate vector linework without heavy mesh clutter, streamlining working drawings and scheduling.

Ideal for custom residential architecture, suburban villas, and boutique hospitality interiors, this half-round transom unit excels when stacked above multi-panel sliding glass doors or French doors. It brings generous daylight into double-height living rooms, formal dining spaces, and sunlit garden rooms. Specifiers searching for arched clerestory glazing, patio door transoms, or semicircular picture windows can readily incorporate this unit into concept models and construction documentation sets.
