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.

Disclosed is a flame-retardant insulation bar manufactured by extruding an insulation composition including any one base resin selected from the group consisting of polyamide, polyurethane, polyester, and combinations thereof, a reinforcing agent, a flame retardant, and an additive.

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.

A sash (2) for a sliding window (1) or a sliding door includes at least two aluminium members (4, 5) connected by one or more insulating strips (7, 8). The two aluminium members (4, 5) and one of the insulating strips (7) at least partially confine a cavity (9) having a first side (10) in a direction (y) perpendicular to a plane (x-z) in which the sash (2) extends and a second side (11) opposite to the first side (10). A low emissivity surface (6a) is disposed along the first side (10) or the second side (11) and has an emissivity of less than or equal to 0.3.

A composite structure for stationary and mobile flat elements, the structure including a two-dimensional infill, in particular multiple glazing or a composite panel, having first composite profiles each having an outer profile, an inner profile and one or more first separation bars connecting the outer profile and inner profile. The connection between outer profile and inner profile is shear-enabled in the longitudinal direction. The outer profile is mounted against an outer side of the peripheral zone of the infill shear-resistantly relative to the infill in the longitudinal direction in a first length portion of at most 5% of the length of the outer profile, but shear-enabledly over the remaining length. The inner profile is mounted against an inner side of a peripheral zone of the infill shear-resistantly relative to the infill in the longitudinal direction in a second length portion of at least the length of the first length portion.
