Abstract:
1. A method of reducing thermal leakage through a gap that is defined by a first end surface of a first insulating structure and a second end surface of a second insulating structure, the method comprising: permanently coupling a bulb seal having a tab portion and a bulb portion to the first end surface such that a first part of the tab portion and part of the bulb portion sealingly abut with the first end surface; wherein the bulb seal is distinct from first and second insulating structures, wherein the tab portion comprises a metal and is configured as a strip along one side of which the tab portion is coupled to the bulb portion, and wherein the bulb portion comprises an insulating material; and permanently coupling the second insulating structure to the first insulating structure such that first and second end surfaces oppose each other and such that the bulb portion and a portion of the tab portion are disposed in the gap and sealingly contacts the second end surface.
