222 CORK INSULATION filler and then with a good elastic enamel, such surface will present an efficient barrier to the entrance of moisture. An elastic enamel is required, to withstand the contraction and expansion of the room surfaces due to changes in temperature. The Portland cement plaster, however, is of such nature as to expand and contract a considerable amount, under cold storage room conditions, so much so that it has long been the practice to score the surface of such plaster finish in four foot squares to confine the checking and cracking to such score marks, or, if you wish, to provide expansion joints, similar to the expansion joints in concrete sidewalks. The weak points in enameled troweled plaster are these score marks, or expansion joints, and especial care must be taken to keep all such cracks so well closed with filler and enamel that little, if any, moisture will contact with the <strong>insulation</strong> through that source. To do this is not as difficult as it may sound, or as some would have us believe; for it is, in many cold storage rooms, entirely feasible and practical to use enameled troweled plaster on walls with entire success, and if to the plaster mix a small portion of some good and suitable integral waterproofing compound is added, the value of the plaster as a protective coating will be enhanced. The service in cold storage rooms of cold storage buildings is not usually as severe, from the standpoint of moisture, as is the service in daily ice storages, milk rooms, poultry chill rooms, and a host of small cold storage rooms in small plants because in cold storage buildings the rooms are not, as a rule, entered nearly as often as are the cold storage rooms in small plants, and when the rooms in a cold storage building are entered it is invariably through anterooms that keep the warm, outside air from rushing directly into the cold storage room and precipitating its moisture upon cool surfaces of every kind. Consecûently, the need for the most efficient protective finish for the interior of cold storage rooms will be in rooms operating at moderate temperatures, such as from 28° to 35° or 40° F., in which rooms the moisture pre- cipitated upon cold surfaces is not converted into frost crystals, or not so quickly converted but that there is an op- portunity for some of it to be absorbed. ;
STRUCTURAL SUGGESTIONS 223 If <strong>insulation</strong> is applied to the underside of ceilings in rooms where the height is limited and cooling coils are either hung near the ceiling or placed close to the ceiling in bunkers, as is usual in the small cold storage rooms to be found outside of cold storage buildings, the finish over the corkboards should always be something more vulnerable than plaster. Either factory ironed-on mastic finish, with all joints carefully sealed upon application, or the very best emulsified asphalt prepara- FIG. 79.—BARUES METAL FLOOR GRIDS. tion, troweled on in two coats, should be used on all such insulated ceiling areas ; and where coil bunkers are used, such special asphaltic waterproof finish should also be used on all walls down at least to the lower line of bunker construction, and often preferably on the entire wall areas of the room. (Plaster should never be applied in rooms to be used for the storage or handling of ice.) Wall finishes containing asphalt will discolor most paints of lighter color unless a continuous coating of orange shellac is first applied to the asphaltic surface, but aluminum paint can be applied directly over asphalt without fear of discolora- tion. Aluminum painted surfaces have the advantage of radi-
