It is a homogeneous board, free fireproof material. from laminations and tendencies to split The nature of the raw materials used, . through the center. permits accurate manufacturing control-- the product is uniform and long-fiber wool. It contains a minimum of non-insulating materials. It is springy and resilient. Low Thermal Conductivity The average established in tests is 0.33 , Btu per hour, per square foot per inch thickness, per degree Fahrenheit difference Low Thermal Conductivity The heat conductivity of Red Top Insu lating Wool (1 -Y<i lb density) is 0.266 Btu per inch thickness, per square foot per hour, per degree Fahrenheit difference in in temperature. Resistance to Moisture , m- Tests show that this board, after being submerged in water for a period' of two (2) . - hours, has an average water absorption of temperatures. (Tests by Professor Peebles, less than 15 per cent. Armour Institute of Technology). Structural Strength Light Weight (Density) In its standard density, Red Top Insu lating Wool weighs but \-Vi lb per cubic The tensile strength is over 300 lb per square inch, and the modulus of rupture, over 500 lb. foot. It is furnished in full and semi Durability thickness. There is nothing in this board that will deteriorate and impair the original insula-- tion value. The Moisture Resistant chemi cal makes the board distinctly distasteful to rodents and insects. Uniformity Adequate laboratory control and mill inspection assure uniformity in density "and structural strength. Insulation Western Felt Works 4029-4117 Ogden Avenue, Chicago, 111. largest independent manufacturers of felt New York Boston Cleveland Detroit Branch Offices St. Louis Cincinnati Los Angeles San Francisco Denver Philadelphia Manufacturers and Cutters of Wool, Hair and Jute Felts WESTERN FELT WORKS, as a leading manufacturer and cutter of FELT, operates a thoroughly modern mill and completely equipped cutting department. Com petent and up-to-date research and laboratory technicians are available at all times without obligation, to anyone whose field touches our products. AVAILABLE IN ROLLS, SHEETS OR CUT TO SPECIFICATIONS--Western Felt products are used most commonly in heating, ventilating and air conditioning installations for eliminating noise transmission and as an insulation against heat tosses and cold penetration. WESTERN FELTS FOR SOUND CONTROL--Noises created by the operation of air conditioning equipment must be entirely eliminated at their source or neutralized and deadened during their course of travel through the air ducts. For such purposes Western Felts are especially adapted for lagging on air ducts, where it does triple duty--as a sound deadener of noises caused by the air conditioner itself--by preventing noises originating outside the system from being transmitted via the air ducts--and, because of its lbw rate of thermal conductivity, it serves as an insulation against heat losses through the duct structure. CUT TO REQUIRED SHAPES AND SIZES--Western Felts serve efficiently, as shock pads under such machinery as oil burners, stokers, fans, blowers, pumps, etc. Western Felts used in this manner counteract destructive vibrations and the resultant noises which would otherwise pass through air ducts to the various rooms. OTHER USES FOR WESTERN FELTS--Fabricated of wool, hair, or jute, Western Felts are available for a wide variety of other uses, such as weatherstrips, anti-squeak strips, insulation material, gaskets, washers, packing material, floor pads--in sheets, rolls or cut to special requirements. Important is the use of felt strips as a dust seal between the room register and wall. APPLICATION OF WESTERN FELT--Strength of fibre, flexibility and easy working characteristics of Western Felts make them simple to handle. Flat surfaces or irregular contours are easily and quickly covered at low labor cost. Write for free samples and further information describing the use of Western Felts for air conditioning units, or other purposes. Applying Red Top Strip Wool between studs. Strip Wool has a waterproof paper backing with a in. flange for nailing to studding. Used as shown it prevents the entrance of moisture into the insulation. 1036 Applying Asphalt Coaled Sheathing Showing how Western Felt is used as mounting material at base of motor and blower units to reduce vibration and subdue noises.
