There are two main varieties of hinged crank windows including awning windows which leave a horizontal opening and casement windows which leave a vertical opening.
Are awning windows better than double hung.
Awning or hung vs.
Casement windows are considered better than double hung windows at keeping out drafts since the window seal is generally quite tight.
Casement windows on the other hand tend to have a slightly tighter seal than double hung windows when they are locked since there isn t a track for casement windows to slide on.
As such when comparing windows it is good to start comparing by type ie.
The tighter the seal of the window the more energy efficient it is.
Let s find out how.
Casement windows do a better job of limiting air intrusion because the window sash pushes directly into all four sides of the window frame like an outside door pressing into a door frame.
With a double hung window its tracking system provides multiple points where air can leak making it less energy efficient.
In fact casement windows can even be opened and closed while seated in a wheelchair though assistance may be needed to operate the latch.

Casement vs double hung the major advantage of casement windows over double hung is that the casement is able to open fully while double hung windows range of motion is somewhat more limited.
