Figure 6-77.-Double-hung windows. Cross sections: A. Head jamb; B. Meeting rails; C. Side jambs; D. Sill.
Basically, the finish frames for all of
these are much alike, consisting principally,

jamb, sill, and outside casing (the inside
casing being considered part of the inside-

Section drawings showing head- and side-jamb
details for a double-hung window are shown
in figure 6-77.
Sill details are shown in
