A spacer profile comprises: a basic body extending in a longitudinal direction of the profile with an outer contour which is substantially rectangular or trapezoid-shaped in a cross-section perpendicular to the longitudinal direction; the body comprising first and second transverse walls connected by a single side wall element and held at a pre-set spacing h; the side wall element ending with a first end at a first edge region of the first transverse wall and with a second end at a first edge region of the second transverse wall; the side wall element forming a path for thermal conduction from the first transverse wall to the second transverse wall, the path length approximately 1.1 or more times the spacing h; and comprising an anchoring protrusion held on the first transverse wall and extends from the body in a direction opposite to the second transverse wall.

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 frame assembly for a window, door or wall comprise trusses that serve as a structural support and a thermal break. The frame assembly includes an inner frame portion and an outer frame portion, with the trusses mounted there-between. The trusses comprise thermally insulating strut members that have a lower thermal conductivity than the inner and outer frame portions, and in some embodiments between can be composed of carbon fiber. The thermally insulating strut members enables the trusses to serve as thermal breaks and provide heat insulation between the inner frame portion and the outer frame portion, while providing structural support to the frame assembly.

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 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 (EMCEMI/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.
