For SI: 1 foot = 304.8 mm.
R-values are minimums U-factors and SHGC are maximums. R-19
					 batts compressed into a nominal two (2) by six (6) framing cavity such that the
					 R-value is reduced by R-1 or more shall be marked with the compressed batt
					 R-value in addition to the full thickness R-value.
The fenestration U-factor column excludes skylights. The
					 SHGC column applies to all glazed fenestration.
"10/13" means R-10 continuous insulated sheathing on the
					 interior or exterior of the home or R-13 cavity insulation at the interior of
					 the basement wall.
R-5 shall be added to the entire slab and the required slab
					 edge R-values for heated slabs or insulation sufficient to fill the framing
					 cavity, R-19 minimum.
"13+5" means R-13 cavity insulation plus R-5 insulated
					 sheathing. If structural sheathing covers twenty-five percent (25%) or less of
					 the exterior, insulating sheathing is not required where structural sheathing
					 is used. If structural sheathing covers more than twenty-five percent (25%) of
					 exterior, structural sheathing shall be supplemented with insulated sheathing
					 of at least R-2.
The second R-value applies when more than half the
					 insulation is on the interior of the mass wall.
