Sash window from Ash Grange, Ash Green, Surrey


This window was part of the alterations and improvements made to the house by the Spode family in circa 1809-11. Interestingly, the joiner adapted a circa 1785-90 window, replacing the top sash with a modified Gothic side-hung casement. These facts came to light when the window was dismantled and repaired.


The glazing-bar profiles to the lower sash are typical of those during the circa 1780-1790 period – a variation of the ‘astragal and hollow’ profile. The upper sash, with its laminated lancet glazing-bars, has a later form of the ‘bead and hollow’ profile.


Examples in the teaching gallery are often partly stripped of their accumulated layers of paint to illustrate the construction and quality of the timber used in particular parts of the window – e.g., close- grained knot-free Baltic pine for the glazing-bars, which were produced by hand at this time.


The teaching gallery also holds a cross-section of typical 18th and early 19th-century moulding planes, which form an important and essential part of understanding sash window development.


Care is taken to preserve areas of original accumulated paint; paint specialists having visited the teaching gallery over the years to research the history of window and door decoration in terms of paint finish

This window illustrates the complex joinery detailing in better-quality Regency sash windows. Note circular pane and arched glazing-bars in margin-lights.


It is planned to partially strip this window to illustrate the joinery methods employed to form these complex shapes in softwood. Students soon become imbued with both enthusiasm and admiration when examining the craftsmanship and skills involved in window and door joinery, particularly of the 18th and 19th centuries
