How Do Sash Windows Work
The principle of a casement window is as follows: a counterweight made of steel or lead balances the shutters. The weight is suspended from a cord that is hidden inside the casement, which has a free space. In old insulating glass units, this part is used for installing thermal insulation.
A traditional sash window can be found in buildings built in the Gregorian or Victorian style. In later periods, people installed similar double-glazed windows with minor changes in design.

Styles of Sash Windows

1. Traditional windows. They are made in elegant design similar to that of the century before last, which makes them perfectly fit the facades of historic houses. Double-glazed windows with a box-shaped sash structure can be customized for them. In this case, choose wood resistant to deformation and twisting. The outer surface remains perfectly smooth.
2. Venetian style. Such casement windows remind of classic double-glazed windows. The characteristic feature is a triple sash with two fixed panes on the outside. The center shutter opens. The weight used to balance the middle sash is housed in the outer frames. The window opens and closes smoothly. The posts between the sections look quite aesthetically pleasing.
3. Georgian style. The glass unit is divided into 6 or 8 small parts, which are harmoniously combined. The items are large enough to fill rooms with sunshine.
There are other options for the design of sash windows. You can choose the architectural style of the Queen Anne revival; in this case, several panels are used on the upper sash, and no more than two on the lower one. There are also arched windows that were popular during the Gothic revival. This is an analogue of rectangular double-glazed windows.
Besides the classic window sash design, many of them have a hidden spring. It preserves the charm of the English style swing windows. The system with cord weights is not used here, as it is replaced by a spring mechanism. Such counterweights don’t look aesthetically nice, so they are neatly hidden behind the window frame.
