Abstract
A unified building opening extension system is pre-built offsite. The extension system provides an airtight, watertight assembly that is compatible with waterproofing and air barrier systems integrated with the assembly when the opening assembly (e.g. door or window), exterior insulation, and veneer are installed on the building wall. Water intrusion or leaks are resisted even under positive and negative air pressure events (i.e., winds and storms). A baffle plate with a vent hole is fitted to a weep hole in the bottom of a frame of the assembly.
