Patent attributes
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.
