Sash windows are a popular type of window with a long history, dating back to the 17th century in England. They are comprised of two sashes, which are moveable panels of glass held within a frame. The sashes can be slid up and down to allow air to circulate while keeping the window closed.

Sash windows have been a mainstay of traditional English architecture for centuries, and they continue to be a popular option for modern homes. With their classic style and practicality, it's no surprise that sash windows are still a preferred choice among homeowners in Clewer New Town, Berkshire, and across the south east of England.
