ABSTRACT:
The present invention is a frame used to support a thin mirrored film. The frame has a front surface which includes a peripheral supporting ridge and an adhering surface. The adhering surface is located adjacent to and outside the peripheral ridge. The film is positioned tautly across the frame, supported by the peripheral ridge and attached to the frame at the adhering surface. The adhesive used to secure the film to the frame is preferably flexible so that it may provide relative lateral movement between the frame and the film, thereby compensating for thermal expansion and contraction differences between the frame and the film. A rear surface of the frame may include a peripheral stacking ridge. The stacking ridge is positioned outwardly from the peripheral supporting ridge relative to the central region so that one frame assembly may be stacked on top of another frame assembly without contacting the tautly supported film that is stretched across its peripheral supporting ridge.
