Since they were easy to open, sash windows let light into rooms without the need for curtains.

Early windows were simple glass, but by the 17th century, sash windows began to become more decorative with coloured glazing bars and moulded mullions. These were very expensive at the time but as glass production improved and cheaper they became a part of numerous period houses.
