A downhole pressure barrier (100) operatively positionable in a subterranean well. The downhole pressure barrier (100) includes a housing (102) having a flow passage (122) formed therethrough. A plug member (124) that is positioned within the flow passage (122) selectively prevents flow through the flow passage (122) and allows flow through the flow passage (122) responsive to contact with an activating agent. At least one retainer assembly (130) supports the plug member (124) within the housing (102). The retainer assembly (130) selectively prevents communication between the activating agent and the plug member (124). An activating assembly including a combustible agent (164) that is positioned between the retainer assembly (130) and the plug member (124) is operable to create a communication path through the retainer assembly (130) upon combustion of the combustible agent (164) to allow communication between the activating agent and the plug member (124).
