AND FOREIGN PATENTS ISSUED AND PENDING Assures Rapid Pull Down of Temperature The low heat storage .capacity of FerroTherm is extremely important in achiev ing rapid pull down of temperature, and in saving refrigeration costs for the initial and each subsequent cooling of space. Specifically, the heat storage capacity of a single sheet of No. 38 gauge is 0.029 Btu per (hr) (sq ft) (F tempera ture difference). This is approximately 1/16 of the heat storage capacity of 1 sq ft of 1 in. thickness corkboard. Permanent, Fire-Proof Insulation Ferro-Therm installed in a cold storage room Ferro-Therm Steel Insulation, made from rigid steel sheets with a special alloy coating, reflects 90 per cent to 95 per cent of all radiant heat. This high reflec tivity, combined with extremely low heat storage capacity, provides maximum insulating efficiency in a minimum over all thickness. Saves Pay Space and Weight In cold storage construction, the number of sheets of Ferro-Therm depends on the temperature to be maintained and the U value required. The k value of FerroTherm, based on tests, is listed in the Data Book of the American Society of Refrigerating Engineers as 0.226 Btu per (hr) (sq ft) (F temperature difference). Laboratory tests and thousands of appli cations have demonstrated that a wall of Ferro-Therm will provide insulating effi ciency equivalent to a wall of mass insulation approximately twice as thick. Ferro-Therm construction eliminates trapping of moisture condensate, with subsequent deterioration of the construc tion. As it is all-metal, Ferro-Therm cannot be penetrated by rodents, vermin or termites, and is absolutely non-com bustible. The value of Ferro-Therm for fire protection is apparent. 125 Below Zero Maintained in Altitude Test Chambers Ferro-Therm has proved its superiority in buildings, cold storage rooms, refriger ated cabinets, locker rooms, dry ice con tainers, refrigerated railway car con struction, ovens, high-temperature storage tanks--in fact, practically every type of application where high insulating efficiency with economies in space and weight are a requisite. The most nota ble demonstration of Ferro-Therm per formance has been its selection for the insulation of altitude chambers for the testing of Army and Navy aviation equipment and pers'onnel. In these chambers, temperatures as low as --125F were maintained, with a tem perature drop of +70F to -- 70F in 10 to 12 min. 1480 Insulation Window Screens Ingersoll Products Division Borg-Warner Corporation 321 S. Plymouth Court, Chicago 4, 111. Koolshade* sunscreen is a bronze min iature Venetian blind with fixed hori zontal bars set at an angle which will keep the greatest possible amount of solar heat load outside of windows. By. reflecting, absorbing, and radiating most of the sun's heat rays outside the window, Koolshade keeps rooms up to 15 cooler and has been shown to account for as much as 75% of the cooling necessary in air conditioning installations. 100 sq ft of Koolshade is equal to 1 ton of refrig eration and costs to % as much. Koolshade provides insect protection equal to ordinary insect screen. Koolshade is framed and applied to windows like ordinary insect screens. Ingersoll distributors can apply Kool shade in patented Koolshade aluminum frames, in Koolshade Quik-on frames which have only top and bottom frame rails held apart in tension by installation hardware or in wood or metal frames. Ingersoll's Sungard* economy sunscreen stamped from aluminum sheet, is in tended for industrial applications and performs the same heat load reducing function as Koolshade at lower cost. Sungard is not insect proof. Sungard is framed and applied by Ingersoll Distributors like Koolshade.
