Sash windows are recognisable by their vertical opening mechanism and are typically associated with traditional architectural styles and designs.
A sash window consists of two framed window sashes – one positioned in front of the other. This is more specifically referred to as a sliding sash window. These windows units sit in
frames with vertical grooves that allow them to move up and down smoothly without any danger of one frame rubbing against the other and damaging it. The up and down movement of the sash is assisted by counterbalances – weights on cords and pulleys.
