The <br /> argument being proposed for not installing rigid insulation <br /> to the outside of foundation walls is as follows: <br /> 1) The situation only occurs where 2' x 4' stud walls <br /> sit to thP outside of the 8" concrete foundation <br /> wall thus exposing 4 1/2" of the top at the wall <br /> to the interior. <br /> ���I 2) The total linear feet at this sitvation is <br /> � approximately 75' . 75' x 4 1/2" = 2£S•1 sq. ft. <br /> i `� 3) Tne 'R' value of the concrete wall is assumed to <br /> � be :ibout equal to double paned glazing or R-1.6. <br /> 4) The area of heated wall is 3,487 sq. ft. <br /> 1 -- <br /> 5) 32� allowable glazing area would equal 1 ,115.8 sq. <br /> , ft. <br /> t� G) Actual glazing area equals 1,054 sq. ft. This <br /> �� <br /> leaves 61.8 sq. ft. to spare. <br /> 7) Since the area of concrete, when added to the <br /> � '� glazing area, does not bring the total over 32g of <br /> '�'� the wall area - then obviously this building would <br /> pass code requirements if a component analysis was <br /> ; ��.,,i,, perf ormed. <br /> ���, ���,��. <br /> ���u;���d. <br /> ��:�-i������„�� <br /> ��,;uaa. <br /> lAt v:� <br /> �����li +1_ y�� F` t t .r <br /> 1�� <br /> il_'�i-ldi0 '�?t � ''-"'. � <br /> x •�:5i�< . , . .
