Alitherm 400 three-pane windows

A wider three-pane window

The example places opening lights either side of a fixed centre pane. Consider how this arrangement looks across the full width of the opening and whether both openers can be reached comfortably. Overall width and individual sash limits must be checked at survey.

Choose this layout in Alitherm 400 for a contemporary casement appearance. Compare the Flush version if you prefer a level external sash.
