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.
