About this asset

Kolbe Ultra Series Sterling cottage double-hung window Revit family features a three-wide mulled unit with unequal sashes and divided lites. This triple-unit window assembly comprises three cottage-style double-hung openings joined with vertical mullions inside a continuous outer frame. Each individual bay incorporates an unequal sash configuration where the upper sash is shorter than the lower sash. Divided lite muntin bars divide the upper panes into a two-by-two grid and the lower panes into a two-by-three pattern, yielding a balanced multi-pane glazing pattern. Detailed exterior brickmould surrounds the assembly, and the primary sash members feature clean rectangular profiles suitable for high-end exterior architectural detailing.

The download is a 1.7 MB 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.

Designed for standard wall-hosted workflows, this Revit family inserts cleanly into exterior envelope wall assemblies. Users can adjust hosting heights, schedule the triple unit in window schedules, and map separate materials to exterior cladding, interior timber finishes, and glazing layers. Elevation views display crisp 2D vector linework for construction drawings and exterior elevation sheets.

Suited for traditional residential architecture, historical renovations, Cape Cod houses, and contemporary farmhouse builds, this window configuration serves as a focal glazing element across living rooms, dining rooms, and primary bedroom facades. It pairs naturally with horizontal lap siding, shaker shingles, natural stone veneers, and perimeter exterior trim boards. Specifiers searching for cottage sash windows or mulled residential fenestration can integrate this asset directly into schematic and design development documentation.
