A heat-insulated metal closure has the following features:
- a fixed frame (1, 21) which is anchored on masonry (2, 22) and is provided on its entire circumferential length with a thermal break, in which a heat-insulating insert (5, 25) is arranged,
- at least one movable element (3, 23) without thermal break,
- a heat-insulating element (10, 30) which extends along the entire circumference of the fixed frame (1, 21) and, when the closure is closed, can bear against the heat-insulating insert (5, 25) of the fixed frame (1, 21) and which completely covers the metal regions of the profiled parts (6, 26) which form the movable element (3, 23), in which connection it holds these, with regard to the ideal separation plane between the outside and the inside of the closure, on the same side, and
- a heat-insulating element (12, 32) which is arranged on the possible sides of the movable elements (3, 23) which do not bear against the fixed frame (1, 21), and which holds the metal regions of these sides, when the closure is closed, on the same side on which this movable element (3, 23) is arranged with regard to the heat-insulating insert (5, 25).
