Sash windows, also called hung, are made with one or more movable panels, that create a frame to hold the panes of glass. The panes of glass are typically separated by narrow muntins. The muntins, also known as glazing bars, are strips of wood or metal.
Essentially, all windows that have this sort of glazing design are classified in this way, yet the term is mostly used in reference to units that have glazed panels that slide horizontally or vertically to. These models are known as sash and case, sliding or Yorkshire light. Robert Hooke, a scientist and inventor, is credited with design of these types of units.
Most Georgian and Victorian homes have these accents. Although the sizes tend to range, traditionally these include six over six panes. This type of design allows for a maximum opening and ventilation of half the total space. Each movable panel includes springs, compression weatherstripping or balances to hold it in place.
To ensure operation, the weight of the panel is often balanced using a heavy lead, steel or cast iron weight or counterweight hidden in the window frame. This weight is attached to the window with a special chain or cord that runs along a pulley at the top of a frame. Sometimes spring balances are used instead. Typically these are constructing using softwood. Most of these structures are single glazed. However, there are double glazed structures available.
There are some common problems related to wooden types. Some of these issues: swelling, woodwork distortion, rattling in windy conditions, problems caused by poor application and rot. The sliding ability of the structures makes them more vulnerable to problems than traditional models.
Despite their high maintenance elements, these structure are also advantageous. Some advantages: physical appeal, utilization of natural resources and compliance with historic building and housing laws. One of the main advantages of sash windows is that they are able to cool the building interiors efficiently, even in warm weather or hot climates.
