FIELD: suspension arrangements for wings.
SUBSTANCE: invention relates to transport. Door leaf (200) for a vehicle, in particular a rail vehicle, comprises door leaf frame (100), first skin (270) and second skin (275), and heat path (280) from first skin (270) to second skin (275) through at least two different materials. Said different materials have a different thermal conductivity, wherein a first material has a lower thermal conductivity than metal, in particular a lower thermal conductivity than aluminium. Door leaf frame (100) comprises at least one profile having at least one web (230) made of the first material, wherein web (230) between two profile parts (210, 220) of the at least one profile (110, 120, 130, 140) is arranged such that first skin (270) is thermally decoupled from second skin (275). In door leaf frame (100) on each of two longitudinal parts (210, 220), there is at least one groove (240) for mounting first skin (270) and second skin (275).
EFFECT: invention improves the heat-insulating and sound-insulating properties of the door.
