When heat tends to flow through such insulated structures, 95 per cent of radiant heat is reflected back toward its source. In summer, stifling outdoor heat is driven off. In winter, practically all sup plied heat is retained in the house where it is needed. The reflection of heat is a revolutionary principle in insulation engineering which has won wide spread recognition and acceptance by engineers and scientists throughout the world. Alfol is now extensively used by many of the largest manufac turing and industrial plants, U. S. Navy, and others, as well as in houses and buildings of every kind and size. Alfol will save up to 75 per cent or 80 per cent of the heat loss that would occur through an uninsulated house. It consequently costs less to heat an Alfol insulated home. Many owners report over one-third saving in fuel costs. Alfol is installed only by Authorized Applica-. tors. All work is done in strict accordance with Alfol Standard Speci fications.

Guide, and are based on new insulating value of aluminum foil tabulated in National Bureau of Standards Letter Circular No. 465, June 4, 1936, which contains the latest available data on the insulating value of aluminum foil. UNAFFECTED BY DAMPNESS ALFOL ADVANTAGES Alfol is non-porous, has no capillarity, cannot absorb moisture. Moisture infiltration in nonmetallic insulations increases conductivity frequently as much as 50 per cent. Such variations cannot occur in Alfol. INSULATING EFFECT Transmittance coefficients (see table above) are determined from tests made on actual wall sections insulated with Alfol. They accurately ^measure Alfol's insulating effect including ' the heat ` loss through and around studs, joists, rafters, etc. Where published coefficients of materials are based on 12-in. by 12-in. panel tests . . . materials preheated in "bone dry" condition and at specified densities . . . they do not include the heat loss at studs, nor the effect of moisture infiltration, variation in density, thickness, etc... Many noted authorities on heat transfer recognize that the performance of Alfol in actual use is difficult to surpass. FIREPROOF GLEAN AND SANITARY No heat-storage capacity. Alfol preheats or cools *n aPProx*mate^y one-fourth the time required for other insulations. Being metal, Alfol is clean. It repels vermin; prevents bacterial growth. pipelines Trained mechanics unreel sheets of Alfol as needed. These compact rolls cause no dust, dirt or waste. Alfol is flanged on edges and nailed to face of studs, joists or rafters, through fibre spacer strips.
