FIG. 108—INSULATING CONCRETE CEILING BY PLACING CORKBOARD IN THE FORMS BEFORE CONCRETE IS POURED. When the insulation is applied on the ceiling after thebuilding is completed, the cork board must be put up froma scaffold placed on the floor below and this requires ex-perienced and high priced labor. The work is done underconditions requiring artiflcial light by which only a super-ficial inspection can be given to the materials and work- INSULATION 183 manship. In Figure 109 is illustrated an insulated ceilingafter the wood forms have been removed, and with the corkready for plastering. In Figure 110 is illustrated a concrete ceiling insulatedwith two thicknesses of two-inch cork board and finishedwith Portland cement. The framework is first erected andmade four and one-half inches deeper than would otherwisebe necessary, and the beam boxes are made of a size whichwill hold the insulation on all three sides of the beam. The first layer of cork is placed over the form boards. FIG. 109—CORK BOARD ON CEILING READY FOR PLASTERING. and laid so that all transverse joints a^re broken. Over thisthe second course of cork board is laid in i/^-inch Portlandcement mortar and nailed to the underlying cork withhickory meat skewers. The boards must be placed so that all joints in the twocourses of cork are broken. The reinforcing steel is thenplaced on top of the cork and the concrete fioor pouredto the required depth. 184 INSULATION When the floor has hardened enough to permit the re-moval of the forms, the cork ceihng is plastered from be-low. The strength of the bond between cork board andconcrete erected in this manner, has been te
