For <br /> floors over outdoor air, such as overhags, the overall U-Value for the <br /> floor shall meet the same requirement as for roofs, U-Value of 0.04. <br /> 2 Slab-on-grade floors. <br /> For slab-on-grade, the insulation around the perimeter of the exposed <br /> floor shall have a minimum R-Value of 6.4. The insulation must <br /> extend downward from the top of the slab a minimum of 3'-6"or <br /> downward to the bottom of the slab then horizontally beneath the <br /> slab for an equivalent distance. <br /> 3 Vapor Barriers <br /> The maximum perm rating for the vapor barrier is 0.1. A minimum of <br /> 4 mil polyetheline, or equal, is required to achieve this. The vapor <br /> barrier must be continuous with all joints overlapped and made over <br /> framing members or blocking. <br /> 4 For notes on foundation wall, see Pg. 6. <br /> 5 For additional assemblies not illustrated, use worksheet on Pg. 8. <br />
