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.

A fenestration assembly includes a glazing unit includes a pane spacer between exterior and interior panes proximate glazing unit edges. A fenestration frame is coupled around the glazing unit and includes a frame core extending around the glazing unit. The frame core includes a unitary core wall including a composite material that is hollow and extends continuously from a core interior face to a core exterior face. A metal glazing cap is coupled with the frame core. The metal glazing cap having a cap end indirectly engaged with the glazing unit along the interior pane, and the cap end is remote from the pane spacer. Each of the core exterior face, the pane spacer and the metal glazing cap are thermally isolated from each other with the frame core including the unitary core wall.

A window frame assembly includes a frame; a setting block including a block body secured to the frame; and a block lip extending outwards from the block body; a glazing bead secured to the frame and the setting block, a bead rib of the glazing bead positioned between the block lip and the frame, the glazing bead and the frame defining a glazing channel; and a lite defining a first edge, the first edge of the lite inserted into the glazing channel.

A window system includes a frame, a glazing assembly held within the frame and including a glass stop attachable to the frame, wherein attaching the glass stop to the frame defines an air pocket between the glass stop and the frame, and a thermal dampening device positioned within the air pocket and defining one or more discrete cavities.

A window system has a window frame that surrounds a window unit. The window frame has a glazing leg with an outer wall and an inner wall. The inner wall forms a J-shaped stem, which forms a J-shaped channel between the inner wall and the outer wall. A first gasket engages with the outer wall, and is maintained in compression between the outer wall and the window unit. Likewise, a second gasket engages with the inner wall, and is maintained in compression between the inner wall and the window unit.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a fenestration unit. In certain instances, the fenestration units, and methods of re-glazing the fenestration units, described herein may be re-glazed from an interior space.

The sliding element includes a sliding plate and a sealing device that includes at least one sealing element, which forms a sealing frame that is arranged on a rear side of the sliding plate and that extends peripherally along an edge of the sliding plate. The sliding plate includes a base plate and a flange plate, which is offset from the base plate, which is connected in one piece to the base plate and which is separated at its edge from the base plate by a circumferential anchor groove, which anchor groove serves for holding the at least one sealing element, which at least one sealing element includes an anchor member that is inserted into the anchor groove and that is connected via a connection body to a compression member.

A system for mounting a panel within an existing window frame. The system includes an elongated deformable bulb, and an elongated carrier. The bulb has a resilient portion, a base section, an extension extending from the base section, and a crosspiece coupled to a distal end of the extension. The crosspiece includes a pair of shoulders at opposite ends of the crosspiece. Each shoulder protrudes laterally beyond the extension. The elongated carrier has a receiving slot opposite a panel gap. The receiving slot has a neck laterally narrower than an interior cavity of the receiving slot. The receiving slot is configured to securely receive the crosspiece of the bulb and to confine the shoulders of the crosspiece.
