A fixed window with a partial arch head split vertically has a shape that resembles an arch with a vertical split or a flat section at the bottom. The window is fixed in place and cannot be opened or closed. The partial arch head shape of the window provides a unique and visually interesting architectural element that can enhance the design of a building.

The fixed design of the window provides insulation and soundproofing properties to the building while allowing natural light to enter. However, the shape of the window can present some challenges in terms of weight distribution and structural stability, which must be addressed during installation. Overall, a fixed window with a partial arch head split vertically can be a distinctive and modern addition to a building's design.
