Abstract: A method of preparing a window module includes providing a metal frame having a first major surface, applying a structural glazing tape to the first major surface of the metal frame, and positioning a glass panel overtop the structural glazing tape. The structural glazing tape includes a polymer foam tape having first and second major surfaces, an adhesive layer overlying the first major surface for bonding the structural glazing tape to the structural frame, and a release layer overlying the second major surface. The method further includes filling a channel defined by the glass panel, the metal frame, and the structural glazing tape with a curable sealant, and curing the sealant to bond the glass panel and the metal frame together.

Abstract: A protectively reflected binary image is provided comprising a thermally imaged transparency on which is superposed a thin reflective protective overcoat, the imaged transparency comprising a binary image supported on a transparent substrate. The reflective protective overcoat is interfacially bonded to the thermally imaged transparency preferably such that the binary image is interposed between the transparent substrate and the reflective protective overcoat. A method for transferring a reflective protective overcoat onto an imaged transparency is also provided, whereby an image surface of the imaged transparency is protected and made viewable as a reflected image, the method utilizing a laminar transfer sheet comprising a carrier web and a reflective protective overcoat, the laminar transfer sheet being laminated onto the image surface with the carrier web subsequently removed to thereby release the reflective protective overcoat, the overcoat remaining bonded to the image surface.
