Figures 4.12(a)(b): Casement windows with solid
timber frames and side- or top- hung (hinged) sashes
are still being made for so- called new- builds and are
referred to as stormproof casement windows – and in
their original form, referred to as traditional casement
windows, they are still being made as replacements
for old- builds. The following horizontal- and vertical-
sections through the detailed parts of (a), Traditional-
and (b), Stormproof- casements will be, hopefully,
self- explanatory.
