Packing house and cold storage construction; a general reference work on the planning, construction and equipment of modern American meat packing plants, with special reference to the requirements of the United States government, and a complete treatise on the design of cold storage plants, including refrigeration, insulation and cost data .. . o layers of cork board might easilybe broken, causing the bottom layer of cork to drop offafter the form work has been removed. The ceiling insulation illustrated by Figure 111 is fre-quently used in buildings of ordinary wood construction orwhere an old building of this type is insulated for cold stor-age purposes. INSULATION 185 To the underside of the floor, or ceiHng joist, is naileda course of yg-inch dressed and matched boards, eitherhemlock or spruce, and to this is applied two layers ofwaterproof insulating paper laid with a 3-inch lap and alljoints sealed with hot asphalt. The first thickness of cork board is securely nailed tothe ceiling with large head galvanized barbed wire nailsand erected so that all transverse joints are broken. Thesecond layer of cork is put up with Portland cement mortaror hot asphalt and additionally secured by being nailed tothe first course. ;iT^- FIG. Ill—DETAIL OF CEILING INSULATION. Ail joints must be broken and made tight between thetwo layers of cork. A finish of Portland cement mortar isgenerally applied over the cork. The objection to thismethod of applying insulation is the probability of moisturecollecting between the joists (where there is a floor above).There being no means of ventilation, the lumber will besoon attacked by wood destroying fungi. It is therefore advisable to place the cork on the floorabove, when this can be done, and leave the joists exposedon the underside. 186 INSULATIONFLOOR INSULATION Cellar Floor Where cellar floors are insulated (Figure 112) theexcavation should be carried down far enough to allow foran 8-inch cinder fill being laid
