I am converting an existing attic with a dormers to a master suite. There is old blown- in insulation between the floor joists. Of course we will be insulating between the rafters now that the “thermal envelope” is changing. The question is whether we must remove the existing blown-in? Also, is it best to carry the insulation up the rafters outside the knee walls, or to insulate across the floor in the eaves areas and then turn up the knee walls to the rafters? Any advise welcome!
