These doors are used for following reasons:
- The wall opening is high and air or light should go through.
- There is no portion of wall above the door and it should be closed with a panel.
Construction like the handed doors, see the corresponding description in section “HANDED DOORS / Description / multipurpose” but with a fanlight consisting of vertical profiles identical to the jambs of the door frame, a top flat profile and a filling with a blind panel or a metal sheet with ventilation holes or a glass. Finishing of the metallic parts of fanlight same like the door.
