A window wall system includes a sill receptor secured to an upper surface of a first floor slab, the sill receptor providing a base and an upright member extending from the base, a head receptor secured to a bottom surface of a second floor slab vertically offset from the first floor slab, and a glazing unit providing a sill, a head, and one or more panels extending between the sill and the head. A first hook defined by the sill is engageable with the upright member. When the upright member is received by the hook, the glazing unit is pivotable about the upright member toward a vertical orientation. A second hook is defined by the sill and receivable within a groove defined in the sill receptor when the glazing unit reaches the vertical orientation.

A clip fastening system for securing a window in a window opening without the use of penetrating fasteners is disclosed. The clip fastening system includes a flange that extends in an inward direction from and around the window opening, a groove that is formed through a facing of a window frame of the window and that extends around the perimeter of the window frame, and a clip mutually engaged with the flange and the groove, thereby securing the window frame within the window opening.

Installation systems and methods for fenestration units configured to be set into a rough opening (RO) from interior side of a building structure or wall. The fenestration units may include a retention system coupled to the frame and operable to exert a retention force on the fenestration unit to maintain positive engagement of the fenestration unit with the rough opening framing and resist extraction of the fenestration unit from the rough opening upon insertion of the fenestration unit in the rough opening from the interior side of the rough opening.

The present invention relates to a fastening means (1) for mounting doors or windows, which comprises frames (2) intended to be mounted in a mounting direction (26) in an opening (3) in a wall, a floor, a ceiling, said fastening means (1) comprises a bracket (5) intended to be mounted on the backside (8) of the frame (2) and at least one screw or bolt (9), intended to be screwed into the end portion (4) of the opening (3), said bracket (5) comprises at least one locking slot (6), said screw or bolt (9) comprises at least one locking projection (11) intended to be pushed into said locking groove (6) for fastening the frame (2). Said locking slot (6) consists of a groove (12) for example an U-formed groove, extending mainly in the longitudinal direction (22) of the frame (2), said locking projection (11) comprises the head (10) of the screw or bolt (9) or a head (10), which is covered by a casing (14) e.g. a housing, which at least in some part encloses the head (10), which presses the first wall (7) of the groove (12) downwards during the mounting, said wall (7) comprises at least of a re-springed backwards projection (21), which is resilient backwards in order to form said groove (12), said locking comprises at least some part of the head (10) of the screw or bolt (9), which is locked in said groove (12) between the first wall (7) and another wall (15), which stops the moving forward of the head (10) during mounting.

Embodiments herein relate to sill cleats for fenestration systems. In an embodiment, a fenestration system is included having a frame assembly including a sill with a bottom side. The bottom side can include a first edge projection, a second edge projection, and can define a cavity. The system can also include a sill cleat with a first angled surface configured to engage the first edge projection upon movement of the sill in a first direction. The sill cleat can also include a second angled surface disposed on an opposite side of the sill cleat from the first angled surface configured to engage the second edge projection upon movement of the sill in a second direction. Other embodiments are also included herein.

The present invention relates to a fastening means (1) for mounting doors or windows, which comprises frames (2) intended to be mounted in a mounting direction (26) in an opening (3) in a wall, a floor, a ceiling, said fastening means (1) comprises a bracket (5) intended to be mounted on the backside (8) of the frame (2) and at least one screw or bolt (9), intended to be screwed into the end portion (4) of the opening (3), said bracket (5) comprises at least one locking slot (6), said screw or bolt (9) comprises at least one locking projection (11) intended to be pushed into said locking groove (6) for fastening the frame (2). Said locking slot (6) consists of a groove (12) for example an U-formed groove, extending mainly in the longitudinal direction (22) of the frame (2), said locking projection (11) comprises the head (10) of the screw or bolt (9) or a head (10), which is covered by a casing (14) e.g. a housing, which at least in some part encloses the head (10), which presses the first wall (7) of the groove (12) downwards during the mounting, said wall (7) comprises at least of a re-springed backwards projection (21), which is resilient backwards in order to form said groove (12), said locking comprises at least some part of the head (10) of the screw or bolt (9), which is locked in said groove (12) between the first wall (7) and another wall (15), which stops the moving forward of the head (10) during mounting.
