I'd be curious to know how your natural stone sills (e.g. granite) were installed if your home has ETICS (=EPS) installed?
One mason says to use staples, another says to just use mounting foam and some mortar. I have another appointment with a third mason, but the confusion for me is already complete.
I found a mason's manual that also lists a bracing option.
Do you have any long term experience with technical reliability?
I would like to avoid the sill being put on top of the EPS and at some point it will sag?
