SAINT-GOBAIN GLASS – FACADE / 21 / SAINT-GOBAIN GLASS – FACADE 20 NON-VISION PART GLASS SPANDRELS Spandrel glass or non-vision glass are used on several buildings to conceal essential components that no one wants to see and are typically located below or on top of the vision glass on each floor of the building. Spandrel made of glass are often used to have a continuous, smooth fully glazed façade. The spandrel glass can be complementary or contrasting in color when compared to the appearance of the vision glass. Whatever the aesthetic sought, Saint-Gobain Glass offers complete services to achieve the desired design and propose spandrel glass harmonized to vision glass in order to assure the homogeneity and the full beauty of the façade. Depending of the desired design of the building, the spandrels can have different «look» and «match» with the vision glass in order to achieve an uninterrupted, pure glass façade, simply harmonized with it or inversely fully contrasted for offering to the façade an original rythmed design. In order to accelerate the decision process and reduce the number of mock-ups, Saint-Gobain Glass have defined a set of propositions of spandrels harmonizing with the vision glass for the 3 configurations mentioned before . For each solar control coated glass from the COOL-LITE ® SKN (II) and XTREME (II) families , propositions are defined by a coating and the color of the enameled glass (referenced by its RAL) based on a methodology developed by Saint-Gobain Glass 11 . VILLA METRO, Warsaw (PL) Architect: DA Dziuba Architects © Saint-Gobain The main component of glass spandrel is the opaque colored glass, comprising uniform enameling on one side of the glass. There are several kinds of spandrel, all presenting some advantages or drawbacks (cost, flexibility, aesthetic, maintenance, thermal performance…). In the following we are considering 3 configurations: • a monolithic glass which may comprise a COOL-LITE ® ST or STBRIGHTSILVER coating with enamel on #2 • an insulated glazing unit (IGU) with Saint-Gobain Glass solar control coatings on #2 and enamel on #4 • a "Shadow-Box" configuration with ventilated cavity, of similar composition comparable to the IGU. 11 So-called “matching” between spandrel and vision glass is a subjective appreciation and is likely to change depending on the observer as well as external conditions. The suggestions presented here are the best results up-to-know based on compatibility and existing product range but are not the only possibilities; for some configurations, no satisfying solution can be presented here. It is always recommended to proceed to real observation based on a visual mock-up.

It also allows to reduce the influence of the lighting and environmental conditions as well as save time and money. Pictures of the above propositions are now available using Saint-Gobain Glass GLASSPRO's technology. With GLASSPRO Live, the Saint-Gobain Glass’ on-demand service of glass facade rendering, architects are allowed to appreciate the look of coated glass as well as spandrels on their own project, as if it was real, before it’s even build, with more possibilities in the spandrels configurations.

Given the variety of enameling products and practical experiences, each processor should carry out tests with its own equipment. 10 Contact Saint-Gobain Glass’ technical support team for further information and assistance. Ask us for the processing guidelines for our different COOL-LITE ® coatings families and on ceramic print on COOL-LITE ® ENAMELING ON COOL-LITE ® SOLAR CONTROL COATINGS Enamels are firstly developed for printing on standard raw soda-lime based float glass. During the tempering process of the glass, the enamels melt and fuse permanently to the glass surface to form a colored ceramic layer. For some applications, there may be a need of enameling coated glass, among others glass spandrels. The processing possibilities are given in the products tables (page 6 to 17).
