A sliding door system having one or more sliding doors, door frames (e.g., static frames of different sizes for different wall thicknesses or adjustable frames that can be used to fit different wall thicknesses), sliding door hardware (e.g., tracks, wheels, soft closers, stops, or the like), header, door receiver, a plurality of seals, or the like. The sliding door system utilizes improvements to the components in order to provide security features, such as electromagnetic (EMC—EMI/RFI) shielding, sound resistance, blast resistance, forced entry and/or ballistic resistance, privacy features, light reduction, fire and/or smoke resistance, or the like to the sliding door system. In particular, the sliding door system allows for the use of the security features with the static or adjustable door frames described herein.

A frame may comprise three or more portions comprising an upper portion disposed adjacent an upper end of an opening and two side portions disposed along either edge of the opening, and in some cases a lower portion adjacent a lower end of an opening. A first frame segment and the second frame segment are adjustable with respect to each other in order to extend around the thickness of the opening. A third segment, such as a soffit segment may be utilized to cover at least a portion of the segments. The first frame segment, the second frame segment, and/or the soffit segment may have one or more barriers located between portions of the segments. The first frame segment may be adjusted with respect to the second frame segment, and the adjustment may be made before or after activation of the one or more barriers.

A frame may include three or more portions having an upper portion disposed adjacent an upper end of an opening and two side portions disposed along either edge of the opening, and in some cases a lower portion when the opening is for a window or some doors. A first frame segment and the second frame segment are adjustable with respect to each other in order to extend around the thickness of the door opening. The segments may have one or more thermal barriers, such as a seal (e.g., u-shaped, v-shaped, or the like seal) located between portions of the segments. The first frame segment may be adjusted with respect to the second frame segment. The adjustment of the segments may be made before or after the one or more thermal barriers are installed.

A door frame for a sliding door system may include three (3) portions having an upper portion disposed adjacent an upper end of a door opening and two side portions disposed along either edge of the door opening. A first frame segment and the second frame segment are adjustable with respect to each other in order to extend around different thickness of different door openings. The first frame segment and/or the second frame segment may have one or more caps, retainers, headers or the like coupled to the frame segments. The caps, retainers, or headers may have portions that are trimmed in order to allow them to mate with portions of the first frame segment or the second frame segment. The adjustment of the segments may be made before or after being installed.

An insulating strip (3) connects profiles (2) of a composite profile (1) for doors, windows or faade elements. At least one of the profiles has a roll-in groove (6) and is composed of a first metal material. The insulating strip (3) includes a strip body (4) composed of an insulating material and extending in a longitudinal direction (z). A roll-in head (5) is formed at a longitudinal edge of the strip body (4). The roll-in head (5) has a cross-sectional shape in a plane (x-y) perpendicular to the longitudinal direction (z) suitable for insertion into the roll-in groove (6). A metal sheet (13) having surface variations (17; 18) covers at least a portion of a surface (10, 11, 12) of the roll-in head (5). At least a portion of the sheet (13) is composed of a second metal material having a tensile strength of 300 N/mm.sup.2 or more.

A frame may include three or more portions having an upper portion disposed adjacent an upper end of an opening and two side portions disposed along either edge of the opening, and in some cases a lower portion when the opening is for a window or some doors.

The segments may have one or more thermal barriers, such as a seal (e.g., u-shaped, v-shaped, or the like seal) located between portions of the segments. The first frame segment may be adjusted with respect to the second frame segment. The adjustment of the segments may be made before or after the one or more thermal barriers are installed.

Devices, systems, and methods related to a fenestration unit are described herein. The fenestration unit may include a frame including a plurality of frame members, wherein the plurality of frame members includes an upper rail member, a lower rail member, a first stile member, a second stile member, the lower rail member including two parallel metallic extrusions a space defined therebetween and a thermal break coupled to the lower rail member and located within the space. The thermal break may include a solid body of thermally insulating material defining a first side portion, a second side portion, and an intermediate portion between the first side portion and the second side portion, the solid body of thermally insulating material being asymmetrical about an X-Y plane.

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.

A spacer, window assembly, method of manufacturing a window assembly, and method of manufacturing a spacer is described herein involving window assemblies having three sheets of material, which will be referred to as a triple pane assembly. Two interior spaces are defined within the window assembly: a first air space between the first sheet and intermediary sheet and a second air space between the second sheet and the intermediary sheet.
