Abstract (en)
Methods, structures and systems for environmental isolation of metal window, transom and mullion surfaces, including in one aspect a metal frame structure configured to receive an operable window, the frame structure having a first thermally insulated polymer component connected to a side of the frame structure at a side wall and spanning a total width of the side wall, and an operable window having a second thermally insulated polymer component connected to a sash assembly, the window configured to close to a position defining a first gap between the second thermally insulated polymer component and the first thermally insulated polymer component and a second gap between the sash assembly and the frame structure. In one aspect at least one seal is positioned in the first gap and abutting both the second component and the first component and at least one seal positioned in the second gap and abutting both the sash assembly and the frame structure to provide improved insulation effectiveness.
