The invention relates to a profiled element (200, 201, 202) comprising at least one hollow member (210), a connecting element (220), and a soundproofing member (700) which is mounted on at least one external wall (240) of the hollow member (210). The soundproofing member (700) has a layer structure encompassing at least two layers (710, 720) which are made of different materials and at least one (720) of which is made of substantially rigid material. The profiled element (200, 201, 202) is characterized in that at least one first layer (710) made of at least partially flexible material is arranged between the external wall (240) of the hollow member (210) and a second layer (720) made of substantially rigid material. |
