Lynne writes again from Clinton, Ohio and sends another drawing: "I am a little confused. Can you look at the attached and tell me if this is what you are suggesting? Can't really lay insulation on the floor behind the knee walls. This is used for storage and has a wood floor. Wouldn't picture 2 be better?"

Answer: Picture two is fine as long as you realize that you will now be heating the areas behind the knee walls. When you insulate, the general idea is to wrap the living spaces with insulation. Again be sure to maintain 1" ventilation under the entire roof deck.
