3. You wrote, "Without radiant barrier, your roof radiates photo voltaic created heat into the insulation underneath it. The insulation absorbs the warmth, and step by step transfers it to the fabric it touches, principally the ceiling. This warmth transfer make your air affliction run lengthier and consumes more Electrical power." You happen to be proper that plywood or OSB roof sheathing can radiate warmth to the highest in the insulation on your attic ground.
