ABSTRACT:
A flexible closure system seals off and insulates openings in external building walls or roofs where structures such as ducts penetrate the walls or roofs. The flexible closure system also isolates the structures from the walls or roofs by absorbing rather than transmitting vibrations. The flexible closure system includes an exterior rubber closure sheet and an interior silicone coated fiber glass fabric closure sheet which are both coextensive with the opening, secured to the structure and wall or roof, and form a cavity which is filled with glass fiber insulation.
