Abstract
An interior insulative window is provided which is mounted outside of the prime window opening to the window opening frame and/or adjacent wall surface. This interior window is internally formed with decorative trim off-site and installed as a single unit which does not penetrate the window opening. The mounting frame can optionally include mounting space for receiving a venetian blind to be retained between the prime window and the interior window. For decorative consistency and/or further thermal efficiency, the corresponding structure can be applied to sliding patio doors.
