Spandrel Glasses Ceramic Frit Coated Spandrelite1 Glass Soandreh'e glass panels are heats:rengtne"eo glasses with a ceramic ;'it color ;_sed Dermanently to one surface. Because Spandre/ite glass canels are installed with the color surface tc tne indoor side df the wall. :ne fused surface is dermanently orotectec ;rom weatner and window cleaning aorasion. Spanareiite glass oanels are heat strengtneneo to a specially selected degree of strength to provide optimum performance in resisting stresses caused bv tne sun's heat and to pro. ide maximum probability that the Spandrelite glass panel, if broken would usually remain fixed in the Naming structure. Special Bronze 7177. and Black 5460. Four additional colors, designated Harmony Spandrelite Glasses, have been found td be particularly effective when matched with the tinted PPG vision glasses: Harmony Graylite 14, Spandrelite 6383. Harmony Solarbronze Spandrelite 6612. Harmony So/argray Spandrelite 6401, and Harmony Solex Spandrelite Glass 6357. Characteristics The heat strengtnenmg of Spandrelite and Insulated Spandrelite glasses makes these products several times as strong as annealed glass of the same thickness. PPG Spandrelite and Insulated Spandrelite glasses are resistant to thermal stress and edge damage, and usually remain in the 1970. should be ordered. Technological advantages m tne production of Spanareiite and Insulated Spandrelite glasses, com bined with the inherent advantages of glass over other spandrel materials, provide Spandrelite glass with an almost limitless application flexibility. The colored spandrel areas of these products are designed to be used with a back-up wail or against a dark background. PPG Spandrelite products are not recommenced for use in transoms, partitions, or other areas without back-up. If areas do not have back-up material, pinnoles and some nonuniformity in ceramic film thickness will be visible. ^ulated Spandrelite v iSS Insulated Spandrelite glass panels ere supplied as an integral factory assembly m which Spandrelite glass panels are backed by 1 - or 2-inch fiber giass insuiation with an aluminum oil vaDor oarrier. or by 54-incn fiber glass insuiation witn galvanized steel framing structure even when they have been broken. When safety considerations re quire greater assurance that broken glass will remain in the spandrel area.

February Ceramic Frit Coating This consists of a layer of durable colored ceramic frit compatible with the base material in its coefficient of thermal expansion and fire fused to the surface of the base glass. Instal lation should be made so that the colored surface is toward the indoor side of the wall. or cement asbestos ooard backing. The unauthorized installation of any ether insuiation or backing material .oids anv warranties. Insulated Spandrelite glass panels assure an excellent insulating system vnen used in walls having adeouate weeo-breathe provisions and com pression contact surfaces for the apor barrier. Soeciai care should be taken with respect to fire safety requirements in high rise ouildings to insure that the factory apolied insulation complies with current specifications. Standard Colors Although Spandrelite and Insulated 5 Irelite glass panels are avail- 'o,. in an almost limitless variety of ustom colors. 10 standard colors have proven to be the most widely used.
