Changes to windows represent one of the easiest ways to dramatically alter the character and appearance of buildings.  \nThere are a number of traditional window types found in the District:  \n10.2 CASEMENT WINDOWS  \nThe most common traditional window type, found mainly in vernacular houses and cottages from the C17 onwards.  \n• The casements are flush with the window frames, the joinery in-plane and without raised features or mouldings (i.e. not storm casements);  \n• The fixed and side-hung opening elements are balanced and symmetrical, the panes of glass of uniform size and proportion within a given window;  \n• The glazing is usually divided up by glazing bars, typically with smaller panes in earlier windows and larger panes in later windows;  \n• The panes may be square or, if rectangular, with the rectangles generally upright;  \n• Judgments about glazing bar pattern should be made on a window-by-window basis, rather than slavishly applying an identical pattern toa range of windows without due regard to variations in the size and proportions of the window openings;  \n• The frames are recessed into the wall, typically by c.75mm or more;  \n• Lintels may be timber (plain or chamfered) or stone;  \n• Sills may be timber, stone or tiled.  \n[2](2 www.west oxon. gov. uk)[ www.west oxon. gov. uk](2 www.west oxon. gov. uk)  \nDesign Guide 10:Windows & Doors  \nTraditional casement window:  \nSingle-glazing  \nTraditional casement window:  \nDouble-glazing  \n[www.west oxon. gov. uk](www.west oxon. gov. uk) 3  \nDesign Guide 10:Windows & Doors  \nWith thanks to Cotswold District Counc i l for a l lowing use of these drawings .  \nA  \nC  \n10.3 SASH WINDOWS  \nA window type that became widespread in the C18 and C19, the vertical sliding sash is characteristic of higher status houses of the C18, but also of vernacular houses of both the C19 and C20. In parts of some settlements in the District – the historical cores of Woodstock and Chipping Norton, for example – the vertical sliding sash window is the dominant window type.  \nWith vertical sliding sash windows, the casements slide vertically within the frame, counterbalanced by sash weights boxed into the framing of the window.  \nAdvances in glass technology, resulting in larger panes of glass becoming increasingly affordable overtime, saw glazing bar patterns alter in the second half of the C19, with fewer and larger panes of glass common from c.1850 onwards.  \nA switch from sash to casement windows, or viceversa, can lead to visually incongruous results, owing to the distinctive proportions of each type of window opening.  \n[4](4 www.west oxon. gov. uk)[ www.west oxon. gov. uk](4 www.west oxon. gov. uk)  \nDesign Guide 10:Windows & Doors  \n10.4 STONE MULLION WINDOWS  \nA distinctive window type found in both vernacular and higher status houses of the C16 and C17 in particular (though also revived in Jacobean style houses of the C19).  \nThe window surround is of stone, and the opening divided up (typically into two or three lights) by vertical stone mullions. Both the surround and the mullions are typically chamfered or ovolo moulded in profile. The window surround may be plain, but over the window is generally a hood mould with lable stops, forming an ‘eyebrow’ over the window designed to throw rain water clear of the window opening below.  \nStone mullion windows are often comparitively more expansive in higher status houses, and occasionally divided horizontally by stone transoms in the case of the largest windows.  \nThe windows themselves are typically metal-framed, the glazing often comprising small panes of glass supported by lead ‘cames’.  \n10.5 DORMER WINDOWS  \nA distinctive and","cbCaisIGOSFiT74Z","https://ap.wps.com/l/cbCaisIGOSFiT74Z","pdf",1623496,11,"English","# 10.1 TRADITIONAL WINDOWS\n## 10.2 CASEMENT WINDOWS\n## 10.3 SASH WINDOWS\n## 10.4 STONE MULLION WINDOWS\n## 10.5 DORMER WINDOWS\n## 10.6 REPAIR AND REPLACEMENT OF WINDOWS","[{\"question\":\"Why does the guide emphasize traditional windows in period properties?\",\"answer\":\"Traditional windows should be retained and repaired, or replaced only on a strict like-for-like basis, because modern inappropriate windows can harm character and appearance in period properties.\"},{\"question\":\"What key features define traditional casement windows in the guide?\",\"answer\":\"Casements are flush with the frames, have balanced symmetrical opening elements, uniform pane sizes and proportions within a window, glazing usually divided by glazing bars, and frames typically recessed by about 75mm or more.\"},{\"question\":\"How does the guide explain the shift in sash window glazing bar patterns?\",\"answer\":\"Advances in glass technology made larger panes more affordable, leading to changed glazing bar patterns in the second half of the C19, with fewer and larger panes becoming common from around 1850 onward.\"}]","Design Guide 10 - Windows & Doors - Traditional Windows and Window Types | PDF",28]
