Hi,   I'm trying to model my wall in Ubakus, and I'm stuck because I can't find one of the materials. (Long story short: the wall is already insulated on the inside, with a mixture of traditional and reflective materials; I am considering insulating it on the outside.)   1. This is the wall as it stands now:   From inside to outside (and top to bottom, within the diagram):   BA18 plaster layer (18mm) 45mm BioFib trio unventilated air layer
