A fenestration assembly includes a fenestration frame having a frame core. The frame core includes a core exterior face and a a core interior face. A core wall of the frame core includes filament reinforced polymer, and the core wall extends between the core exterior face and the core interior face. One or more core cavities are within the frame core and surrounded by the core wall. At least one insulation scaffold is seated within the one or more cavities. The insulation scaffold includes one or more scaffold walls and scaffold cavities bordered by the one or more scaffold walls. Engagement feet are coupled with the remainder of the insulation scaffold, and the engagement feet are engaged against the core wall.

A window frame system for fixing at least a first panel, includes at least a first window frame structure which includes at least a first window frame profile having at least first and second holders, and at least a first thermally insulating element with sixth and seventh holders. The second holder and the sixth and/or the seventh holder of the first thermally insulating element include at least one internal corner with a radius smaller than 0.5 mm. In this way, the dimensions of the window frame profile may be smaller than in the known window frame profiles. This may be advantageous for the total insulation value of the window frame system and the quantity of material required/used for the window frame profiles. Also disclosed is a thermally insulating element, a method, a window frame structure, a flexible profile, a control system and a sun protection system.

Example aspects of a shear plate for a window frame assembly, a window frame assembly, and a method for insulating a window frame assembly are disclosed. The shear plate for a window frame assembly can comprise a shear plate body defining an outer shear plate surface and an inner shear plate surface, the shear plate body defining a first end, a second end opposite the first end, and a pair of lateral sides extending between the first end and the second end; and at least one pair of shear plate holes extending from the outer shear plate surface to the inner shear plate surface, the pair of shear plate holes oriented such that a line running through a center of the pair of shear plate holes is substantially parallel to the first end and the second end.

A portal can include at least one rail and at least one stile, each end of each rail connected to an end of each stile such that the portal defines a frame, wherein at least one stile can include a first stile and a second stile; a thermal strut arranged between the first stile and the second stile, the thermal strut being of an insulating material; and an insulative bar arranged between the first stile and the second stile, the insulative bar being of an insulating material.

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 main-frame bar and/or to a wing-frame bar for a main frame and/or a wing frame of a window, of a door, or of a faade element includes a main profiled element having a substantially U-shaped cross-section in single- or multi-piece design, which has, as viewed in a cross-section, a short leg, a long leg, and a transverse leg formed therebetween. A free intermediate space is formed between the ends of the short leg and of the long leg facing away from the transverse leg, a cover element and/or a fitting part extending over the intermediate space at least in some sections. The short leg and the long leg of the main profiled element have multi-function contours on the inner sides thereof facing each other, which multi-function contours completely or partially bound at least the following groove: in each case, a fastening groove open in the same direction on the side facing away from the transverse leg for fastening a corresponding fastening means of the fitting part or of the cover element.

A window frame system for fixing at least a first panel, includes at least a first window frame structure which includes at least a first window frame profile having at least first and second holders, and at least a first thermally insulating element with sixth and seventh holders. The second holder and the sixth and/or the seventh holder of the first thermally insulating element include at least one internal corner with a radius smaller than 0.5 mm. In this way, the dimensions of the window frame profile may be smaller than in the known window frame profiles. This may be advantageous for the total insulation value of the window frame system and the quantity of material required/used for the window frame profiles. Also disclosed is a thermally insulating element, a method, a window frame structure, a flexible profile, a control system and a sun protection system.

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.

A method of assembling a portal can include obtaining a stile, wherein the stile can include a first stile and a second stile; arranging a thermal strut and insulative bar between the first stile and the second stile, wherein the insulative bar can define a lock groove; arranging a lock assembly within the lock groove, wherein the lock assembly can include a fastening plate rotatably coupled to the lock assembly; and coupling the lock assembly to the stile by rotating the fastening plate and, thereafter, engaging fasteners to provide friction between the fastening plate and the insulative bar.

A main-frame bar and/or to a wing-frame bar for a main frame and/or a wing frame of a window, of a door, or of a faade element includes a main profiled element having a substantially U-shaped cross-section in single- or multi-piece design, which has, as viewed in a cross-section, a short leg, a long leg, and a transverse leg formed therebetween. A free intermediate space is formed between the ends of the short leg and of the long leg facing away from the transverse leg, a cover element and/or a fitting part extending over the intermediate space at least in some sections. The short leg and the long leg of the main profiled element have multi-function contours on the inner sides thereof facing each other, which multi-function contours completely or partially bound at least the following groove: in each case, a fastening groove open in the same direction on the side facing away from the transverse leg for fastening a corresponding fastening means of the fitting part or of the cover element.
