Abstract
A sliding double hung window structure allows a window opening to be fully exposed to the external environment in an open position, with casements or windows being stored out of sight, and not in the opening. The window structure includes two casements or sashes balanced by suspended counterweights and guided by pins in guiding grooves in the two vertical sides of the sash. In the closed position, the casements are located in the same plane, one on top of the other. When fully opened, a breast cavity under the window receives the two casements in guiding grooves which communicate with guiding grooves in a vertical section running along the whole height of the window opening. A horizontal section connects the two vertical sections.
