Does anyone know how to model slab insulation in OS? Because the insulation is only for 24" around the perimeter I was not sure how to model this. Do you just mess with the insulation on the construction until you get the correct F-Factor? Also, there is a F-factor Ground Floor Constructions drop down under the Library now, but nothing is in it. Also, it appears all of the slab constructions on the BCL do not have exterior insulation.
