The term sash windows can be confusing. When learning about the structure of windows, it can help to use the comparison of a door’s structure. Both have casements that give stability and frame the entire structure. A door has a panel that opens and closes. Windows open and close differently, but the glass could be compared to the door panel, but it is fragile and needs something to safely contain it. The sash of a window is what frames the glass pane. Sash also can refer to the panel of glass and sash together as a unit. How the window opens and closes is what determines its style.
Hinged windows come in three different basic styles. Hoppers are often used in basements and are hinged at the bottom, opening inwardly. Awning windows are hinged at the top and swing outwardly. Casement windows, commonly called crank-outs, have hinges on the side and crank outwardly.
Another style of window more common in tropical climates is the louvered window. Many small lengths of glass panes are mounted in an overlapping horizontal pattern and are swiveled open for air circulation.
In order to purchase new windows it is important to understand the different styles. A double hung window is what is meant when people say sash window. Simply explained, double hung means two sashes hung in a frame, where either one or both can vertically slide open.
People sometimes use the term single hung when referring to a double hung window in which the upper sash does not move. Technically, this is incorrect. Two sashes are still hung within the frame, so it is still double hung.
A sliding window is a window in which two or more sashes are arranged to slide horizontally instead of vertically. Like a double hung window, the sashes slide past one another on a track.
People usually call double hung windows sash windows. A sash balance is a system of weights, pulleys and cords that give balance to old double hung windows so they would stay in place when lifted. Without the sash balance, the window would have to be propped open by something strong enough to hold its weight. New sash or double hung windows operate on a spring loaded system instead.
To cut down on noise pollution and boost a home’s energy efficiency, a homeowner can replace old double hung windows with new ones. Both of these things can be accomplished by filling the empty space left behind by the old sash balance system with foam insulation and installing new air tight double hung windows. New windows contribute more to a home than just looking nice. They also have the advantage of more efficient options, like a tilt out design that allows the owner to wash or paint the window on both sides easily.
