Insulation INSULATION The Pacific Lumber Company 100 Bush Street, San Francisco 4, Calif. 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 fills 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.

Michigan Ave., Chicago 4 ALFOL MULTIPLE LAYER REFLECTIVE INSULATION Introduced in 1929, ALFOL was one of the first reflective insulation blankets. Today, after nearly three decades of continuous development, ALFOL still is in the lead. Its patented blanket design insures high thermal efficiency, positive condensation protection and rapid, low cost application. Ideal for all types of residential, commer cial and industrial use. ALFOL is also favored in air conditioned structures, where the superiority of reflective insulations provides substantial cooling economies. What ALFOL is: Insulation consists of multiple aluminum foil sheets that auto matically space themselves on applica tion to form two, three or four reflective air spaces. The number of these spaces varies with ALFOL Type, but all types have a rugged, vapor-proof liner that provides continuous moisture protection and. positive application support. How ALFOL works: Patented blanket checks all 3 forms of heat transfer. Mul tiple aluminum foil sheets reflect 95 per cent of all radiant heat . . . instantly, continuously. Block heat loss by convec tion, too. And the multiple -"captive" air spaces minimize heat loss by conduc tion. Result: unparalleled year-'round efficiency! Practical advantages of ALFOL: Ther mal efficiency is the big factor, but there are other reasons for ALFOL popularity. Its heavy liner provides sag- and ripresisting application and a continuous vapor barrier. Its light weight (Jfo lb/sq ft) cuts rafter load. And ALFOL is as clean, odorless, durable as aluminum it self. Priced low. . . with compact design offering added savings in handling. ALFOL is quick and easy to apply: You simply cut to length and staple across the faces of studs, joists or rafters.
