Lockport Mills, Inc. Thennal and Acoustical INSULATION Dept C. Lockport, N. Y. Insulation Moisture-Resistant--Chemical I reatment, combined with natural protective coating on cotton fibres, enables cotton to effectively resist moisture. Prevents rot and mildew. Smooth Texture--No sharp particles to irritate the skin. Flexible--Cotton batt may be ex panded or contracted to fit any enclosure. Easy to Warehouse and Handle. Offers far more "compressibility." Requires one-third the trucking and warehouse space of ordinary insulation. Five featured types to meet every insu lation need: (1) OPEN BLANKET backed Simple and Economical to Install. Saves from 25 to 40 percent in costs. by tough, waterproof, asphalt-coated kraft paper to form an effective vapor barrier. (2) ENCLOSED BLANKET. Insulation completely enclosed in enve lope, asphalt-coated paper on one side, porous or "breather" type paper on other. (3) OPEN ALUMINUM FOIL. Designed to Maintain Maximum Util ity. Resists all types of deterioration. Won't sag or settle. Packaged in Rolled Form. Thicknesses--inches: 1, 1J, 2, 3, 3%. Width--16, 20, 24 in. centers. Lengths: Standard from 12 ft up. All the features of Open Type (1) plus the extra value of aluminum foil backing. Effective vapor barrier . . . stops 90 per INSULATING VALUE OF VARIOUS INSULATORS* cent of radiant heat. (4) ENCLOSED ALUMINUM FOIL. Superior ip insula tion plus values and thermal efficiency. (5) DOUBLE FOIL, aluminum foil on top and back, plus superior Lo-K Blanket efficiency for tops in insulating value. Thennal Conductivity--The "k" value for cotton is 0.24 Btu/hr/sq ft/degree F/inch. (See table.) Light Weight--Weight of 1 cu ft is % lb. (See table.) Flame-Proofed--Withstands 1800F blow torch heat. The coefficients of conductivity (k value) are expressed in Btu per hour per square foot per degree Fahrenheit per 1 in. of thickness.

THE VOID-FREE INSULATION FOR REFRIGERATION FOR HOMES OR COMMERCIAL USE PALCO WOOL INSURES SUSTAINED EFFICIENCY AND LOWER OPERATING COSTS FOR REFRIGERATED AND AIR CONDITIONED STRUCTURES NO POCKETS--NO VOIDS Entire wall is insulated before interior finish is applied. Self-supporting Palco Wool is then inspected to eliminate any possibility of pockets or voids. NO JOINTS Palco Wool forms a continuous insulating barrier. As a uniform unbroken mass, it fill.s every nook and cranny--hugs every surface. With Palco Wool, there are no problems of heat leaks due to improper fitting at edges and around structural members. NO SETTLEMENT Examine Palco Wool fibers. You will see the corkscrew-like structure which gives lifetime resilience and freedom from settlement. NO TRAPPED MOISTURE Palco Wool is impervious to moisture effects and deterioration. It is installed with no intermediate vapor dams to trap moisture. NO CONVECTION CURRENT LOSSES Palco Wool displaces so much air and breaks it up so completely that convec tion currents are virtually eliminated.
