Sash windows have been used in England since the late 17th Century. They are still extremely popular today, adding a touch of class and elegance to a property. A sash window consists of a moveable panel, that traditionally moves up and down in a vertical manner. They are most commonly found in Georgian and Victorian homes. A typical design consists of 3 glass panes in the upper frame and 3 glass panes in the bottom. The windows are balanced by a metal sash weight which is hidden inside the frame and connected to the window by a braided cord which runs over a pulley.
Hereís a look at the history of sash frames and their 21st Century alternative.
Sash windows have been used in English homes since the late 17th Century. The trend caught on after they were installed in the royal palaces of Hampton Court and Kensington. Not only did they become a fashionable addition to homes of the aristocracy, but they were also considered more practical than wrought iron casement windows. Their vertical opening system was less intrusive and didnít change the exterior facade and the larger glass panes were stronger. Sash windows were at their most popular in the Georgian, Victorian and Edwardian periods.
Beautiful as original sash windows are, they can cost a great deal to maintain. Timber frames will warp and shrink over time creating gaps, resulting in draughts,† and wood is particularly susceptible to rot, especially the cills. Another common problem is frayed cords which compromise the systemís integrity and can be dangerous if the open frame shuts down quickly. Over painting can also make the windows stick and not shut properly. This is also a security risk; in fact, properties with old sash windows are a prime target for intruders because they are easier to break in to.
Thanks to todayís modern technology and design techniques, itís possible to replicate traditional wooden 19th Century sash windows with practical modern systems.
