Double-hung windows are one of the more traditional styles of windows.
A double-hung window is a window that features an upper and lower sash that slide vertically one after the other in a single sash. Perhaps one of the more traditional styles of windows, this type of window typically features the lower sash in front of the upper sash. Each sash can be a solid pane of glass or can be divided into lights separated by recessed braces or, for decorative purposes, can have a snap-in removable grille to create the illusion of separate lights.
Double-hung windows can be installed by a professional or an experienced do-it-yourselfer.
A double-hung window is designed with two slots in the side jambs that allow each window sash to slide apart from each other. Some have a full window screen, allowing ventilation from the top or bottom of the window at any time, while others only have a half screen that needs to be positioned accordingly. The ability to have a ventilation area equal to half of the total window area is one of the reasons the double suspension design is so widely used.
This window style is also a popular choice for replacement windows. It is valued primarily for its versatility. Some of the features of modern double-hinged windows include insulation for greater energy efficiency, tilting strips that facilitate external window cleaning, and UV protection.
In addition to versatility, double-hung windows are also stylish. They are available in vinyl and wood sashes and additional features such as transoms can be used with them. Also, a double drop-down window can be arranged in different ways. Single window units can replace a worn out or dysfunctional window. In groups of three or more, double windows fill a larger wall space while retaining the ventilation and versatility that a panoramic window lacks.
Installing a double-hung window is quite quick and simple and can be done by an experienced do-it-yourselfer or a professional. A professional window company can usually replace all the windows in an average home in less than two days. While replacing windows of any kind adds value to a property, a two-walled window is almost a guaranteed value because it is a stylish and functional window.
