A method for producing insulating profiles comprises manufacturing a profile body and a first functional element separately, and the profile body and the first functional element are supplied to an ultrasonic welding device, wherein the profile body and the functional element are connected to one another by a material bond by formation of a welded joint. The profile body and the functional element are brought together into a predetermined first cross-sectional geometry during formation of the welded joint and are thereafter guided in this cross-sectional geometry until the plastics material of the welded joint solidifies to such an extent that the profile body and the first functional element are fixed in the predetermined cross-sectional geometry.

An insulating strip (3) connects profiles (2) of a composite profile (1) for doors, windows or faade 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/mm.sup.2 or more.

A window, door, or facade element includes an outer frame composed of out frame bars and a leaf frame composed of leaf frame bars. One or more of the outer frame bars and/or of the leaf frame bars has/have at least the following features: a base profile, on which two fastening grooves that are open in the same direction are formed for fixing a corresponding fastener of a fitting arrangement, which bridges the intermediate space between the fastening grooves. The two fastening grooves have at least one latch for at least one counterpart latch, which can be attached without tools, of a fitting part arrangement. The fitting arrangement has a functional fitting on a fitting plate and at least one support element for supporting the fitting. The support element is designed for direct or indirect latching in the fastening grooves by means of the counterpart latch.

A metal door frame for a door opening comprising at least one first door frame segment for upper or side portions of the door opening, the at least one first door frame segment having a first molding flange, a first jamb face adjacent to the molding flange, and a first stop flange adjacent to the jamb face.

Provided herein are thermal break structural members for use in fenestration assembly products. In some embodiments, the thermal break structural member is monolithic with an infill retainer, being designed to bear a structural load while maintaining the overall integrity and thermal performance of the conjoint fenestration unit.

The invention relates to a profiled plastic section (1) for a metal/plastic composite profiled section (31). The profiled plastic section (1) comprises a first profiled element (2) and at least one second profiled element (3). The first profiled element (2) and the second profiled element (3) together form a latching mechanism (4, 9; 5, 10; 6, 11), by means of which a form-fitting connection can preferably be produced between the first profiled element (2) and the second profiled element (3) in a width direction (x) and in a height direction (y). The first profiled element (2) and the second profiled element (3) overlap preferably over a large area when the form-fitting connection is produced between the first profiled element (2) and the second profiled element (3), and the form-fitting connection can be produced on the cross-sectional plane (x, y) between the first profiled element (2) and the second profiled element (3) by latching the profiled elements (2, 3) of the profiled plastic section (1). The form-fitting connection between the first profiled element (2) and the second profiled element (3) is designed such that a movement of the first profiled element (2) and the second profiled element (3) in a longitudinal direction (z) of the profiled plastic section (1) is allowed when a first metal component (29) is connected to the first profiled element (2) and a second metal component (30) is connected to the second profiled element (3) preferably in a shear-resistant manner. The profiled plastic section (1) can likewise also be designed with more than two profiled elements (2, 3), and the basic principle according to the invention of generating a shear-free plastic/metal composite profiled section (31) can be carried over.

An insulating body for multi-shell construction elements for spacing apart and thermally separating at least two profiled section elements relative to each other has a base member with a first side and a second side opposite the first side. Fastening projections are arranged on the first and second sides of the base member and secure the insulating body in receptacles of the profiled section elements. At least the first side has two of the fastening projections. The base member has a hollow chamber with an inner guiding contour for receiving and guiding fitting parts. A multi-shell construction element with at least two profiled section elements is provided with at least one such insulating body.
