Part of my basement is unfinished & unheated with the ceiling joists open to below & currently uninsulated , the floor above those areas in the house is much colder than the floors in the rest of the house. It seems to me that it makes sense to me to insulate the basement ceiling between the joists in the unheated part of the basement. The joists are open so installing insulation should be straightforward. Has anyone done this? Have any suggestions on how to proceed? "R" value I should use? I live in New Jersey.
Thanks
Dennis
