FIELD: construction. ^ SUBSTANCE: invention concerns construction industry, particularly the window and door sealant design. The flexible profiled sealant has a top and bottom parts made in the form of a hollow profile. The top part has at least one mounting rib. A covering rib is provided to cover the fitting slot. The top part has a sealing area and support area adjacent to it, both located at an obtuse angle to each other. One end of the sealing area is connected to the back via a connecting section, which has a V-section recess on the outside, the side faces of the recess are inclined at an obtuse angle to each other. The connecting section is made in the portion going from the V-section recess bottom towards the back with continuously increasing width. The support area is directly adjacent to the back or to a transverse area going from it, the furthest end of which is connected to the support area or to the covering rib end facing the back. connection point of the support area and back, transverse area, respectively, is located above the covering rib and shifted from it. The support area is adjacent to the sealing area to form an articulated joint with it. ^ EFFECT: better tightness between a profile and a surface to be sealed. ^ 13 cl, 6 dwg |
