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.

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 profile for a fenestration system includes a first portion and a second portion offset from the first portion and thereby defining an inner space therebetween. The profile for a fenestration system further includes a retention mechanism arranged within the inner space, and one or more communication lines mounted to the retention mechanism.

A system for adjusting infill panel or operable fenestration frame in an operable fenestration. The system can include a setting block adjustment device and an operable fenestration frame such as a door rail or window sash with glass, acrylic, polycarbonate or other infill material. The setting block adjustment device can include a lug, a threaded fastener, a setting block support plate, and a setting block. The lug is slidably captive within a groove in an outer face of the operable fenestration. The threaded fastener engages a threaded aperture within a blind hole in the lug. The fastener end engages the setting block support plate and setting block to adjust the infill panel.

Disclosed is a fixed frame or opening frame, resulting from an assembly of joinery profiles, forming the mullions and the cross-members of the frame, with the profiles of the mullions and the cross-member profiles being assembled by their ends. The frame includes at least one device for compressing, including at least one mechanical connection extending interiorly along an intermediary portion of the frame, the at least one mechanical connection connecting by its ends of supports of the device for compressing, the supports being integral respectively with mullions or cross-members, on either side of the intermediate portion of the frame, the mechanical connection being solicited in traction in order to provide the maintaining under constraint of the ends of the joinery profiles of the intermediate portion of the frame against the corresponding ends of the joinery profiles, arranged on either side of the intermediate portion, belonging to the mullions or cross-members.

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 composite profile for doors, windows, or other facade elements includes a first and second metal profile between which at least one intermediate metal profile is provided. The first metal outer profile is connected to the intermediate metal profile in a first insulating web zone via one or more insulating web(s), and the second metal profile is connected to the intermediate profile in a second insulating web zone via one or more insulating web(s). Both the first and second insulating web zones have different shear strengths orthogonally in relation to the cross-sectional plane of the composite profile.
