Specialty Shape Windows

Arched, circular, triangular, elliptical, and fully custom geometric forms — for projects where the standard rectangle is only the starting point.

Specialty shape windows include round-top arches, full circles, ellipses, triangles, trapezoids, and fully custom geometric forms configured to fit any opening. They are most commonly specified in heritage restorations, gable-end accents, stairwell features, and high-design residential projects where architectural character is a priority. Because specialty shapes are typically non-operable, the focus shifts to the frame profile, glass composition, and how the unit integrates with the surrounding architecture. Marvin Ultimate offers broad custom shaping capability with a full range of interior and exterior finishes.
