Highly Efficient Form--Two panes welded into One Metal-Sealed Unit, to be glazed in a single sash. Sales Offices in Principal Cities Thermopane--two panes of glass, with an air space between, sealed with metal-- provides efficient insulation for glass areas. Practically any type of flat glass may be used in Thermopane. It may be made up of two sheets of glass of identical type, such as two sheets of Plate, Window or Figured Glass, or one light may be clear and the other figured. Again, to meet certain summer heat conditions, the outer light might be Aklo Heat-Absorbing Plate Glass and the inner light either clear or obscure. Generally speaking, the types of glass that are practical with Thermopane are limited only by the types of glass available and the particular problem in volved. With Thermopane, the heating engineer and architect have available an excellent means of insulating large areas without sacrifice of vision. Where privacy is desired or diffused light an essential, fixed walls or partitions. Thermopane insulates the year round--it keeps heat inside in winter, outside in summer. WIDE SELECTION OF THERMOPANE FABRICATIONS Generally speaking, the design effects obtainable with Thermopane are limited only by the types' of flat glass available.

CONSTRUCTION--A single Thermopane unit con sists of two panes of glass separated by an air space which is hermetically sealed at all edges with metal. The glass used in Thermopane for exterior use ranges from Double Strength A Quality to 14 in.; %6 in. and K in. Polished Plate Glass, with a standard K in. air space. For interior use, the air space Thermopane was used very effectively in this picture window to insulate may be either in. or H in. a large area both winter and summer. The air space between the two mirror-clean lights of glass is dehydrated and her Thermopane again fully solves the prob- metically sealed with a metal band at the lem. In addition. Thermopane may be set factory--thus dirt and condensation with in movable or sliding sash to eliminate in the air space are avoided. 1020 i Insulation Windows Libbey-Owens-Ford Glass Company Toledo, Ohio.

A plus tolerance of Y2 in. fr in. and thinner glass and a plus tolerance of He in. for glass over Y in. thick shall be allowed over the specified thickness. EDGE TOLERANCE--Obviously Thermopane is only available in stock sizes or special sizes to order. In listing cutting sizes, figure Y in. shorter and narrower than the opening size for lights, up to 24 in. square. Above 24 in., for any dimension, the cutting sizes should be ^16 In. under the opening size. SASH SIZES AND WEIGHTS--Be cause Thermopane is heavier than single glass, allowance for greater sash balances must be made in double hung sash. (See detail for weight). Rabbet Width Dimensions: To insure coverage of the edge construction, rabbet widths for lights under 24 in. for any di mension should be Y$ in. For lights over 24 in. for any dimension, the width should be J46 in. to Y in. Rabbet Depths: This dimension should not be less than 1 in. for Y in. air space and Yg in. thick glass. Somewhat more shallow rabbet dimensions can be success fully used, however, if the bright copper color of the metalized edges are allowed to be partially exposed to view. Increase the rabbet depth correspond ingly for thicker glass. (See detail.)
