Balanced Aesthetics

Sash windows are generally comprised of two sliding sashes, each retaining a double-glazed, sealed unit. In most cases, the window will be “split” equally in the height so the visible glass will be the same height in each unit, although in Scotland, 1/3and 2/3 splits or 40/60 splits are commonplace.

However it’s important to have clean lines that run vertically through the upper and lower sashes, so that the plant on bars align and to ensure the Georgian squares will be of equal size.

Look closely at neighbouring houses and you’ll soon see the mishmash of glazing panes, because cheap mock sash or imitation sash windows tried to mimic these important fenestration details but failed.
