Do i need faced insulation between floors. The main reason why you do not need insulation on the floors is simple. Sometimes adding insulation to the floor can cause problems for your home. Faced or the type with paper is typically used in first time applications such as in walls ceilings floors and in crawl spaces. Floor insulation can sometimes reduce the room temperature below the dew point.
So in an attic the paper faces downward and in a crawl space it faces upward. Floor insulation can hamper the dynamic of vapour barriers and thermal resistance. Unfaced insulation the type without paper is what you would use if you are adding insulation to your attic or to place between floors when living space is above and below. Doing so can even cause problems.
The floor does not belong in the building envelope. Sticking your vapor barriers and thermal resistance into places besides the exterior building shell can create odd interior dynamics. Any time you use a faced insulation the paper needs to be facing toward the living space.
