Single-hung windows are a very common and traditional widow. The primary difference between a single-hung and a double-hung window is that a single-hung window will only have one sliding sash that opens and typically from the bottom.

Single-hung windows have several advantages that can make them an attractive option for new construction or replacement windows.

 

Cost: Single-hung windows are often less expensive than double-hung windows.

Energy Efficiency: As with most windows, when accompanied by the Energy Star efficiency rating and properly installed, single-hung windows can provide a measurable energy savings over older non-Energy Star rated windows.

Application: Similar to double-hung windows, single-hung windows can be a good option for most applications. They come in a wide variety of styles, colors, finishes, sizes and are available in most brands.
