Hey all, there used to be a picture that was published in radon manuals defining what the eave of the home is. On a gutter side it was above the gutter. On the sides of the home without the gutter it had a dotted line across the bottom of the "A" and defined that as the eave on a non-gutter side of a home. The rules related to windows and opening remain the same. Does anyone have a copy of this picture. This is something that a lot of mitigators struggle with interpreting.
