What Defines a Sash Window?
A sash window is composed of one or more movable panels, or "sashes," that form a frame to hold panes of glass. Generally, these sashes slide vertically, supported by a system of concealed weights, sheaves, and cords (in older designs) or modern spring balances.

The setup of these windows is important. In a "single-hung" window, only the bottom sash moves while the top sash remains fixed. In a "double-hung" window, both the leading and bottom sashes are operable. The ability to reduce the top sash is especially valued for its function in natural convection and air flow.

This offers a natural option to cooling.

For ground-floor rooms or bedrooms, opening the leading sash enables fresh air while keeping the bottom sash firmly closed and locked. This reduces the danger of burglars going into through an open window and avoids passersby from looking straight into the living area.
3. Safety for Children and Pets
Property owners with young kids frequently choose top sash ventilation. By keeping the bottom sash closed and just using the upper opening, there is a substantially reduced threat of unexpected falls, providing comfort without sacrificing air flow.
