ABSTRACT:
A deformable seal for breaches in architectural barriers is composed of a gel material surrounded by a retaining structure. The seal, when used where a member penetrates such a barrier or in a gap between two such barriers allows repeated limited amounts of generally axially movement of the member or barriers while retaining structural continuity and insulating ability.
