What describes a ribbon window?

A ribbon window is characterized by its design as a horizontal band of windows that are typically aligned in a row. This architectural feature often integrates multiple window units to create a continuous glass expanse, which not only enhances natural light within a space but also provides a modern aesthetic appeal. The design is commonly found in contemporary or mid-century modern architecture, emphasizing clean lines and a connection between the interior and exterior environments.

This style contrasts with other window types, such as a single large sliding window or a series of vertical windows, which do not possess the horizontal continuity that defines ribbon windows. Additionally, while decorative frames can enhance a window's appearance, they are not a defining characteristic of ribbon windows themselves. The focus on a cohesive visual line across a facade is what makes the horizontal band format distinctive and effective in architectural design.
