In architecture, Postmodernism is associated with the reuse of styles from previous periods, as well as the use of many colours, forms, and materials. Postmodernism is a sort of heir to Historicism and a reaction to the Modernism’s minimal, monochrome, and modular design language.

Though projecting top-hung and and projecting side-hung windows were developed during this period, there was not a specific type of window characteristic of Postmodernism. However, the energy crisis of the 1970s had a significant impact on window design. Windows became smaller, and focus shifted to energy optimisation.
