Doors and windows provide access and ventilation in buildings. Doors consist of a frame and shutter, while windows consist of a frame and sashes or shutters. There are various types of doors and windows classified by their construction, operation, and purpose. Proper installation of door and window frames is important to ensure they function correctly and do not become damaged over time.

29. INSTALLING DOOR FRAMES
Frames which are improperly built-in can cause
problems later, when the plastering is done orthe
doors are hung. Therefore we must give special
attention to setting the framesproperly.
A door frame should be fixed in such a way that the
door can open flat to the wall. Otherwise, the door will
form a lever to the frame, and the hinges will be forced
out when the door swings wide open suddenly.
Door frames can be fixed in position either duringthe
masonry construction or after the walling has been
completed.

30. INSTALLING WINDOW FRAMES
Installing window frames is similar to installing door
frames (see Door Frames section). A window frame
should be fixed in such a way that the casement can
open flat to the wall, otherwise the casement will
forui a lever with the edge of the wall. This can cause
the hinges to be forced out when the window isblown
open by the wind.
Window frames can be installed either during the
construction of the walls, or after the walling hasbeen
completed.
