IDEAL FILL INSULATION FOR REFRIGERATION OR AIR CONDITIONED STRUCTURES REFRIGERATION REQUIREMENTS COMPLETELY FULFILLED BY VOID-FREE PALCO WOOL Extremely low thermal conductivity over a wide range of mean temperatures is due to low conductance through the material itself, void-free application pro viding full insulation without pockets or joints, and virtual elimination.pf convec tion current losses. Initial and operating economy result from low material cost, simple structural requirements, ease of installation, efficiency minimizing re frigerating equipment requirements, and permanent effectiveness proved through exhaustive in-place field tests. Fire re tardant by nature, Palco Wool is further protected by the unique Saferized proc ess. Odorless, repellent to rodents and insects, and moisture resistant, Palco Wool is ideal for freezers, coolers, con trolled atmospheres. AIR CONDITIONING EFFICIENCY INCREASED BY PALCO WOOL IN HOME OR COMMERCIAL USE Maximum performance of home or com mercial air conditioning and heating equipment is assured by Palco Wool's unique combination of qualities. It is recognized to have one of the highest efficiency ratings of all insulations. Per manent resilience guards against settle ment, providing full insulating effective ness for the life of the building. Not only is natural fire retardance increased by the unique Saferized process, but Palco Wool also resists breakdown or melting under high temperatures. Free from odors, non-irritating, moisture resistant, repellent to rodents and insects, Palco Wool has proved its effectiveness for public or private building insulation. Low cost, ease of installation, and light weight recommend it from the stand point of architects, designers, applica tors and users.
