6. Sash Window
Design
In early windows, the sash box is
exposed and flush to the outside
wall.
From 1709, the sash box had to
be set back four inches.
From 1774 onwards, the sash box
had to be recessed behind the
brickwork.
During the
Georgian period,
sash window
design changed
because of fire
regulations.
