A door comprises a door frame having frame-members (1-4), which extend along the edges of the door. The door is clad on one flat side thereof with an outer panel (8) which is nailed to the frame members and also to at least one nailing batten (9, 10). The nailing batten has a thickness which is smaller than the thickness of the frame members. A continuous sheet (5) of insulating material provided with grooves (11, 12) for accommodating the nailing batten fills the hollow cavity located inwardly of the door-frame members. The insulating sheet (5) and the door-frame members (1-4) surrounding the insulating sheet are covered on each flat side thereof with a covering sheet (6, 7), to which they are glued. The door is manufactured by forming an insulating sheet (5) which fits into the space located inwardly of the door frame and which has a thickness corresponding to the thickness of the door frame, by forming in the insulating sheet one or more grooves (11, 12) whose depth is smaller than the thickness of the sheet, and by placing nailing battens (9, 10) in the grooves (11, 12) and gluing the insulating sheet (5), the nailing battens located in the grooves, and the frame-members (1-4) to the covering sheets (6, 7), and then nailing the outer panel (8) to the door structure thus obtained. |
