As clearer and larger sheets of glass became available, sash windows began to replace hinged casements. They were glazed with plate glass placed within timber frames with rebates and then pinned with glazing sprigs, and then putty on both sides to ensure they were watertight. This kind of glazing gradually superseded leaded lights.

Sashes were introduced, which led to increased demand for ironmongery.
