A partition for forming a barrier in a channel has a molded resin-based plate and a plurality of thermally expandable pellets attached to one side of the plate. The partition is secured in place in the channel by mounting brackets. As heat is applied, a blowing agent in the pellets is activated and the pellets expand to many times their original volume. The resultant foam seals the gap between the plate and the surrounding structure and further secures the plate in place. The partition is particularly useful in forming a sound/water/air barrier in an automotive cavity.
