I have a two-story house. Half the house has a cathedral ceiling (which will be left as is) and the other half has a traditional attic with no soffits. The only ventilation in the attic comes from two gable vents at each end of the house.
How should I insulate this type of attic? I am contemplating adding insulation to the bottom of the roof deck and adding more insulation to flooring in attic; I think this is called a sealed attic. Is this appropriate for my climate?
