DIRECTIONS FOR CORKBOARD ERECTION 307<br />

Then start with a full-width and 9-inch l<strong>on</strong>g piece of <strong>cork</strong>-<br />

board and set the sec<strong>on</strong>d row of full-size <strong>cork</strong>boards <strong>on</strong> top<br />

of the first row, thus breaking vertical joints in the sec<strong>on</strong>d<br />

layer, and all joints in the sec<strong>on</strong>d layer with respect to ail<br />

joints in the first layer. As each <strong>cork</strong>board is set, butt it<br />

tightly at all points of c<strong>on</strong>tact against the adjacent boards and<br />

additi<strong>on</strong>ally secure to the first layer with wood skewers<br />

driven obliquely, two per square foot. Join and seal the wall<br />

<str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> tightly wMth the ceiling, cutting pieces of <strong>cork</strong>board<br />

neatly to fit.<br />

Give the asphalt cement ample time to cool and set, say<br />

12 hours, before applying a finish over the <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g>.<br />

136.—Double Layer <str<strong>on</strong>g>Cork</str<strong>on</strong>g>board, Freezing Tank Bottom, in<br />

Asphalt Cement.—See that the c<strong>on</strong>crete base is well adapted<br />

to the ]nirpose and presents a reas<strong>on</strong>ably smooth and level<br />

surface, remove all dirt, loose mortar, or other foreign material,<br />

or arrange to have these several items taken care of by<br />

those resp<strong>on</strong>sible for such preliminary work, before making<br />

preparati<strong>on</strong>s to apply <strong>cork</strong>board over the surface of the freez-<br />

ing tank foundati<strong>on</strong>.<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 surface<br />

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

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

Asphalt cement, first a row of <strong>cork</strong>boards in a straight line<br />

against the outer edge of the area of the tank bottom insula-<br />

ti<strong>on</strong>, closely follow with a sec<strong>on</strong>d and a third row of <strong>cork</strong>-<br />

boards, each row lagging behind the preceding <strong>on</strong>e, in the<br />

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

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

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

Break all joints between the different rows, by starting<br />

alternate rows with half-length boards, and see that all joints<br />

are butted tight. Carry the <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> <strong>on</strong> both ends and both<br />

sides to the outer limits of the end and side <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> of the<br />

tank, cutting pieces of <strong>cork</strong>board as required to finish out such<br />

dimensi<strong>on</strong>s.<br />

*The dimen-i<strong>on</strong>s of the tank bottom area to be insulated shall be enough wider and<br />

l<strong>on</strong>ger than the size of the freezing tank, so as to overlap the <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> to be installed<br />

<strong>on</strong> the vertical ends and sides of the tank.
