(Total, 6 reflective spaces.) It is easily and quickly installed between wood joists, furring strips, and between steel trusses, metal beams, and girders. The normal installation rate Detween wood joists is 2,000 sq ft a day. The If cu ft carton contains 500sq ft, weighs 40 lbs. Standard width, for 12 in., 16 in. and 24 in. centers. Standard Type 4, for 12 in., 16 in., 24 in. centers. Heat flow through wall space, which is air, is 5 per cent to 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 aluminum surfaces THROWS BACK 97 per cent of the heat rays which strike it. As emittive surfaces, they emit ONLY 3 per cent of heat actually absorbed by conduction, convection and radiation. Practically all building materials, including ordinary insulations, absorb and emit 90 per cent of heat rays, against Infra's 3 per cent. CONDUCTION:--One sq ft of Type 6 Infra weighs only If os, has only If cu in. mass. The ratio is 1 of Infra mass to 431 of low conductive air. Ordinary insulation, when dry, has a ratio of 1 of mass to 23 of air. CONVECTION and VAPOR:--Each of the 3 tough aluminum sheets of Infra has ZERO permeability to all gases, including heated air, cold air, and water vapor. 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, reverse, triangular, reflective air pockets. The construction, and the lack of weight for heat exchange, make Infra Insulation abso lutely non-condensation forming. Neither can it absorb nor store moisture. Infra Insulation uses 99.5 per cent pure .0009 in. and .002 in. aluminum, made in accordance with special Infra emissivity requirements. It has 17 lbs and 52 lbs bursting strength (Mullen test), 800 per cent to 2600 per cent greater than ordinary foils. The tearing strength is 28 grams and 80 grams (Elmendorf test). The special fiber separators are permanently flame-proof, mold-proof, and vermin-resistant. FIRE:--Since Infra emits practically no heat rays, and since aluminum's melting point is 1250 F, it has actually prevented the spread of fire. SANITARY:--Infra is sanitary, inhospitable to vermin, and DOES NOT RETAIN odors. Mechanics like to work with Infra. It is CLEAN, free of DUST or lint, with permanent freedom from floating particles. INFRA, TYPE 4 JR. is half (1) inch in depth. Can be used in 1 in. spaces be tween furring strips; in brick or masonry walls; around metal ducts; and under floors, ordinary or radiant heated.
