A seal assembly for an enclosure, which attenuates or eliminates frequencies through the enclosure, and including a non-magnetic electrical conducting membrane on a door frame to which the door seals. Also, means for opening the door from either of its sides which means do not cause any frequency leakage through the door in its closed mode. The membrane is formed in segments, one of which is contiguous to and engages a magnetic member disposed in a pocket formed in the door assembly. Other segments constitute resilient formations in the membrane and by which the magnetic member resiliently receives the door upon its engagement therewith. The opening mechanism mounted on the door to each of its sides engages corresponding door frame elements to cause the door to be opened without in any way preventing the door from completely sealing with the door frame in its closed mode.
