Infra Insulation, Type 6, is a tough, 3-aluminum-sheet insulation, with 6 heat-rayreflective surfaces, plus two other reflective spaces, and four rows of inner, alternat ing, reverse triangular air spaces. (Total, 6 reflective spaces.) It is easily and quickly installed between wood joists, furring strips, and between steel trusses, metal beams and girders, giving the entire area in between, including the edges, full depth pro tection against heat and vapor flow and condensation formation. The normal installa tion rate between wood joists is 2,000 sq ft a day per man. The cu ft carton con tains 500 sq ft, weighs 46 lbs. Standard width, for 12 in., 16 in., and 24 in. centers. Standard Type 4, for 12 in., 16 in., 20 in., 24 in. centers. Heat flow through wall space, which is air, is about 7 per cent by Conduction; 15 per cent to 28 per cent by Convection; and by Radiation, 65 per cent to 80 per cent. ABSORPTIVITY and RADIATION:--Each of Infra's 6 accordion aluminum surfaces has an absorptivity of 3 per cent and a reflectivity of 97 per cent for radiant heat or radiation. Their emissivity is only 3 per cent. The surfaces of most building materials, including some insulations, have an absorptivity and emissivity of over 90 per cent for heat rays as against Infra's 3 per cent. CONDUCTION:--One sq ft of Type 6 Infra weighs only 1} oz, has only cu in. mass. The air-to-mass ratio of Infra by volume is 431 parts air to 1 part mass. For many insulations, when dry, it is only about 23 parts air to 1 part mass. CONVECTION and VAPOR:--Each of the 3 long, continuous, tough aluminum sheets of Infra has ZERO permeability to all gases, including heated air, cold air, and water vapor. Infiltration under flat stapled flanges is slight. The 2 fiber separators also retard CONVECTION. NON-CONDENSATION-FORMING:--The 3 aluminum sheets together with TWO inner accordion separators, which permanently prevent metal-to-metal contact, form FOUR inner rows of alternating, reflective air spaces. The construction, and the low heat storage capacity, minimize condensation formation on or within this type of insulation. Infra Insulation uses 99.5 per cent pure aluminum, 0.0009 in.' and 0.002 in. thick, made in accordance with special Infra emissivity requirements. It has 52 lbs and 17 lbs bursting strength (Mullen Test), 28 grams and 80 grams tearing strength (Elmen- dorf Test), which is up to 2600 per cent tougher than commonly used foils of less than 0.0005 in. thickness having up to 3 lb bursting and 10 gram tearing strengths. The special fiber separators are permanently flame, mold, and vermin resistant. FIRE:--Because its aluminum surfaces have very low emissivity (3 per cent) and a very high melting point (1220F), Infra has actually prevented the spread of fire. SANITARYInfra is sanitary, inhospi NOTE COMPLETE END TO END INSULATION table to vermin, and DOES NOT RE TAIN odors. Mechanics like to work with Infra. It is CLEAN, free of DUST or lint, with permanent freedom from floating particles. 1 INFRA TYPE 4 JR. is half Q4) inch in depth. Can be used in 1 in. spaces be tween furring strips in brick or masonry walls; around metal ducts, etc. Write for a free copy of the sixth revised edition of "Simplified Physics of Vapor and Thermal Insulation," a manual by Alexander Schwartz, on the theory, practice and installation of insulation against heat and vapor flow and conden sation formation. 1602 Insulation Window Screens Ingersoll Products Division Borg-Warner Corporation 310 S. Michigan Ave., Chicago 4, HI. KoolShade* Sun screen is a bronze min iature Venetian blind with fixed hori zontal louvers set at an angle which will keep the greatest possible amount of so lar 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. Common measure: 100 sq ft of Koolshade is equal to 1 ton of refrigeration and costs 3^ to as much. Koolshade provides insect pro tection equal to ordinary insect screen. Ingersoll franchised distributors apply Koolshade in rolled or extruded alumi num frames featuring the patented lacer wire that holds Koolshade in uniform tension.
