For floors of heated or mechanically <br /> cooled spaces over unheated spaces, the overall II-Value <br /> for the floor shall not exceed 0.05. For floors over outdoor <br /> air, such �as overhangs, the onerall II-Value for the floor <br /> shall meet the same requiremeat as for roofs, II-Value of <br /> 0.04.• <br /> 2) Slab-on-qzade floors. For slab-on-grade, the insulation <br /> around the perimeter of the exposed floor shall have a <br /> minimum R-Value of 6.4. The insulation must extend downward <br /> from the top of the slab a minimum of 3'6" or downward <br /> • to the bottom of the slab then horizontally beneath the <br /> slab for an equivaleat distance. <br /> 3) Vapor barriers. The maximum perm rating for the vapor <br /> barrier is 0.1. A minimum of 4 mil polyetheline, or equal, <br /> is required to achieve this. The vapor barrier must be . <br /> coatinuous with all joints overlapped and made over framing <br /> members or blocking. � <br /> 4) For notes on foundation wall see paqe 6. <br /> 5) For additional assemblies not illustrated use worksheet <br /> on page 8. � <br /> 5 <br />
