Corner trim detailing with exterior insulation
I’m in the process of planning a house with exterior mineral wool insulation. If I use horizontal Hardieplank lap siding (clapboards), what is the best practice for attaching the exterior corner trim?
Should I make a corner furring strip using 2 pieces and screw it into the framing diagonally with extra long screws? Or is there another preferred method?
I made a picture (sorry it doesn’t use standard construction drawing standards, hopefully it is enough to get the point across).
