STRUCTURAL SUGGESTIONS 183<br />

Each case that arises must be c<strong>on</strong>sidered <strong>on</strong> its own merits. Generally<br />

speaking, however, it may be said that under average c<strong>on</strong>diti<strong>on</strong>s,<br />

the thicknesses of . . . <strong>cork</strong>board that can be ec<strong>on</strong>omically<br />

installed for the several temperatures noted, are as follows:<br />

ORIGINAL RECOMMENDATIONS FOR CORKBOARD THICKNESS<br />

Temperatures Thickness<br />

—20° to — S° F 8 inches<br />

— S° to +5° F 6 inches<br />

S° to 20° F 5 inches<br />

20° to 35° F 4 inches<br />

35° to 45° F 3 inches<br />

45° and above 2 inches<br />

For the bottom of freezincj tanks, five inches or preferably six<br />

inches of . . . <strong>cork</strong>board should be employed; around the sides the<br />

same thickness of <strong>cork</strong>board, or twelve inches of granulated <strong>cork</strong><br />

securely tamped in place.<br />

The method of arri\ing at these recommendati<strong>on</strong>s mig-ht<br />

not now c<strong>on</strong>form with the data and informati<strong>on</strong> available, but<br />

the experience of man_v years has taught that these recommendati<strong>on</strong>s<br />

for pure <strong>cork</strong>board were then sound to a remark-<br />

al)le degree.<br />

Reference has previously been made to a class of <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g><br />

i:s:rs who came to believe that it Avas not profitable to employ<br />

as much insidati<strong>on</strong> as rec(^mmended by resp<strong>on</strong>sible manufac-<br />

turers, or wlio came to believe that cheaper materials in about<br />

tlie same thicknesses would suffice. It was pointed out that<br />

the}- were much in the minority, yet their numbers justified<br />

c<strong>on</strong>siderati<strong>on</strong> of their policy.<br />

The factors that influence this class of buyers are:<br />

(h) Uncertainty as to the success of the undertaking.<br />

(b) Building <strong>on</strong> leased property, or building <strong>on</strong> owned property<br />

the value and/or utility of which is subject to quick change.<br />

(c) Excess refrigerating machine capacity available.<br />

(d) Insufficient initial funds available for best equipment.<br />

(e) Expansi<strong>on</strong> as part of plan to prepare business for sale, c<strong>on</strong>solidati<strong>on</strong><br />

or refinancing.<br />

(f) Work in charge of an architect, engineer or c<strong>on</strong>tractor who<br />

follows the practice of specifying materials and labor of but<br />

average quality for the sake of wide competiti<strong>on</strong> and the<br />

lowest price.<br />

(g) Influence of the practices of the business being c<strong>on</strong>ducted,<br />

such as <strong>on</strong>e offering average or indififerent quality product at<br />

average or low prices, up<strong>on</strong> the purchase of products, supplies<br />

and equipment.<br />

(h) Lack of true knowledge of the importance of adequate refrigerati<strong>on</strong><br />

and <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> equipment.
