Sash windows are made up of two glazed panels called ‘sashes’ and are either single or double-hung. Moving up and down on a vertical slider, single-hung sashes have only one moving panel, while double-hung means both sashes move. Our sliding sash windows can be tilted open to allow for easy cleaning.
