For floors over outdoor <br /> air, such �as overhaags, the overall II-Value for the floor <br /> shall*meet the same requirement as for roofs, II-Value of <br /> 0_04.- <br /> 2) Slab-on-grade floors. For slab-oa-grade, the insulation <br /> around the perimeter of the exposed floor shall have a <br /> minimum R-Value of 6.4. The iasulation 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 hori�zontally beneath the <br /> slab for an equivaleat distance_ <br /> 3) Vapor barriers. The max>>ntun perm rating for the vapor <br /> barriez is 0.1. A minimum of 4 mil polyetheline, or equal, <br /> is required to achieve this. The vapor barrier must be . <br /> continuous with all joints overlapped and made over framing <br /> members or blocking_ <br /> 4) For notes on foundation wall see page 6. <br /> S) For additional assemblies not illustrated use worksheet <br /> on page 8. <br /> S <br />
