DIRECTIONS FOR CORKBOARD ERECTION 299<br />

width pieces in proper positi<strong>on</strong> to the floor or roof area, in a<br />

straight line, in the first row against the edge of the wall.<br />

Prepare suitable Asphalt cement in reas<strong>on</strong>able quantity,<br />

transfer it to the point of erecti<strong>on</strong> in buckets, flood the sur-<br />

face to be insulated with the molten material, uniformly over<br />

a small area or strip at a time, layf down quickly in the hot<br />

Asphalt cement first the row of half-width <strong>cork</strong>boards against<br />

the edge of the wall, follow with a sec<strong>on</strong>d row of full-size<br />

<strong>cork</strong>boards starting off with a full-width and 9-inch l<strong>on</strong>g piece,<br />

and then wuth a third row of full-size <strong>cork</strong>boards starting off<br />

with a half-length board, each row lagging behind the pre-<br />

ceding <strong>on</strong>e, in the laying, by the length of <strong>on</strong>e-half board.<br />

In this way, all joints in the sec<strong>on</strong>d layer of <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> will<br />

be broken with respect to all joints in the first layer. Keep<br />

the <strong>cork</strong>boards in each row in perfect alignment, so that the<br />

joints in the rows to follow may fit close and seal tight. When<br />

the opposite end and the opposite side of the floor or roof<br />

area is reached, cut pieces of <strong>cork</strong>board neatly to fit and seal<br />

with the wall lines.<br />

When <str<strong>on</strong>g>complete</str<strong>on</strong>g>d, if the <strong>cork</strong>board was laid as floor insu-<br />

lati<strong>on</strong>, flood the top surface with the molten material to an<br />

even thickness of approximately ^-inch, and leave in readi-<br />

ness for the c<strong>on</strong>crete* w^earing floor; if the <strong>cork</strong>board w^as<br />

laid as roof <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g>, leave the surface of the <strong>cork</strong>board<br />

uncoated in readiness for the roofing c<strong>on</strong>tractor to lay the roof.<br />

132.—Single Layer <str<strong>on</strong>g>Cork</str<strong>on</strong>g>board, Between Partiti<strong>on</strong> Studs<br />

with Joints Sealed in Asphalt Cement.— Erect 2-inch x 4-inch<br />

permanent studs, in a vertical positi<strong>on</strong>, 36 inches apart, in the<br />

line of the partiti<strong>on</strong>, so that the 2-inch dimensi<strong>on</strong> runs with<br />

the wall thickness. Place permanent studs, with a lintel be-<br />

tween them, where cold storage doors are to be set, so as to<br />

form an opening the size of the cold storage door frame.<br />

Use door bucks and lintels 2 inches in thickness, and anchor<br />

securely to the floor and ceiling in such manner that they may<br />

take up and withstand any shock from the operati<strong>on</strong> of the<br />

cold storage door.<br />

Prepare suitable Asphalt cement in reas<strong>on</strong>able quantity, <strong>on</strong><br />

the basis of <strong>on</strong>e-quarter pound per square foot of partiti<strong>on</strong><br />

*If wood floor is desired over double layer of <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g>, instead of c<strong>on</strong>crete, then<br />

sleepers must be embedded in the sec<strong>on</strong>d layer of <strong>cork</strong>board, as outlined in Article 144.
