IN 34 COUNTRIES TECHNICAL DESCRIPTION OF ALFOL Alfol consists of one or more sheets of pure aluminum foil.installed to build up heat insulation by providing barriers against the passage of heat. Sheets of Alfol block air currents and seal against moisture. The metallic surfaces reflect heat radiation and eliminate 95 per cent of this form of heat flow. Alfol has the dual advantage of being light in weight and low in heal absorption, and conduction through the separated layers of foil is negligible. Alfol is also furnished combined with other materials such as aircell asbestos for specialized applications. -... PERMANENCE The outstanding quality of Alfol is its permanence. It resists fire and water, it is not affected by vibration, shrinking, settling, bulging, warping. Alfol is a lasting material. Every aluminum surface oxidizes as soon as it is formed. The oxide is transparent and forms a protective film. On the pure aluminum of which Alfol consists, this film is continuous and forms a coating which protects against atmospheric conditions. The reflectivity of Alfol with this oxide film is 95 per cent. After years of service, Alfol tests at 95 per cent reflectivity. EFFECTIVE AS VAPOR BARRIER Alfol is a recognized vapor barrier. Being pure metal it cannot absorb moisture and moisture cannot penetrate it. Alfol is a dry insultaion. U. S. RECORDING GAUGES--U. S. Recording Gauges are made in 8)4, 10 and 12 in. sizes for pressures from 1 lb up to 50,000 lb, and for vacuum. Cases, may be cast-iron or cast brass for wall mounting or flush, mounting. Pen arms are made of. non-corrosive metal. Especially designed clock movements are used. Charts can be furnished for customary time periods. U. S. DIAL THERMOMETERS--U. S. Dial Thermo meters are of the vapor tension type with open scale reading in the central and upper portion of the scale. Cases may be cast-iron, cast brass, drawn steel or drawn brass for wall mounting or flush mounting. Supplied in all sizes from 2 to 12 in. inclusive, for temperature ranges from -- 40 F to 800 F. Furnished with rigid connection bulb or with flexible capillary tubing up to 100 ft long. 1 1010 SERVICE EXPERIENCE The first large applications of Alfol were made in this country in 1931 and in Europe four years earlier. Eight years here and twelve years abroad have proven Alfol's reliability and permanence. Millions of square feet of Alfol aluminum foil in ships, refrigerators, refrigerator cars, trucks, locomotives, pipes, ovens, houses, etc., prove as efficient today as when installed. The high insulating efficiency of Alfol is constant. Data on Heat Savings Effected by Alfol Construction Wood Shingle Roof (no lath and plaster)..............
