Thinking about adding insulation to the attic, which is floored over. The easiest thing would be to put insulation on top of the flooring. However, I need part of the space up there for storage. If, say, I put insulation all around except for an area in the middle, would that eliminate most of the gains of insulation? In other words, if I leave
20% of the space uninsulated, do I cut heat loss by 80% (of what I would by insulating all over)? -- H- posted
