We just purchased a 3-story brick home with 8.5 ft ceilings and want to get the home insulated (using a professional). We would like to have insulation blown into the walls. My questions are:
1. Would interior or exterior be better for creating holes to insert the insulation. I would like to go with exterior due to the number of holes and mess that would occur with interior application.
2. Is cellulose the better product to use in this in this instance (older brick home)?
