摘要

The door element (1) has a timber frame (9) comprising three solid timber slats (16-18) that are separated from one another by vapor barrier layers (19, 20) i.e. aluminum films. The frame is provided with an insulating core (10) i.e. vacuum insulation panel, which is surrounded by planar vapor barrier layers (26, 27). A pane (11) made of glass and/or plastic or a filling is provided within the frame or the core. Facing sheets (12, 13) i.e. medium density fiber-board (MDF) plates, are arranged on sides of the door element. Gaskets (21, 22) are arranged outside the vapor barrier layers.
