INSULATING STRIP FOR DOOR, WINDOW OR FAÇADE ELEMENTS, COMPOSITE PROFILE FOR DOOR, WINDOW OR FAÇADE ELEMENTS, AND METHOD FOR FINISHING MANUFACTURING OF A ROLL-IN HEAD OF AN INSULATING STRIP FOR DOOR, WINDOW OR FAÇADE ELEMENTS
INSULATING STRIP FOR DOOR, WINDOW OR FAÇADE ELEMENTS, COMPOSITE PROFILE FOR DOOR, WINDOW OR FAÇADE ELEMENTS, AND METHOD FOR FINISHING MANUFACTURING OF A ROLL-IN HEAD OF AN INSULATING STRIP FOR DOOR, WINDOW OR FAÇADE ELEMENTS
An insulating strip (3) connects profiles (2) of a composite profile (1) for doors, windows or façade elements. At least one of the profiles has a roll-in groove (6) and is composed of a first metal material. The insulating strip (3) includes a strip body (4) composed of an insulating material and extending in a longitudinal direction (z). A roll-in head (5) is formed at a longitudinal edge of the strip body (4). The roll-in head (5) has a cross-sectional shape in a plane (x-y) perpendicular to the longitudinal direction (z) suitable for insertion into the roll-in groove (6). A metal sheet (13) having surface variations (17; 18) covers at least a portion of a surface (10, 11, 12) of the roll-in head (5). At least a portion of the sheet (13) is composed of a second metal material having a tensile strength of 300 N/mm2 or more.
