I went to a seminar about attic insulating materials and this is what I learned. If you already have blow-in insulation in your attic you shouldn't need more fiberglass. Instead, you will want to install a reflective radiant barrier insulation. Fiberglass and cellulose are designed to slow down heat escaping so you eventually lose most of your heat through the ceiling regardless. You need something to re-direct the heat once it passes through the blow-in insulation. Radiant Barrier will reflect a majority of the heat back once it escapes your blow-in insulation. I bought some Ecofoil online and just rolled it out over top of my existing blow-in insulation, it was very easy.
When installing radiant barrier over the attic floor you must use the perforated radiant barrier for maximum breathability. Moist air that is created inside your home must be able to escape as it rises through your ceiling. If a perforated radiant barrier is not used, the moisture will be trapped in between the barrier and your ceiling. When trapped this will cause condensation to form inside the building materials and insulation creating damage and mold.
Cellulose insulation is proven to outlast the house it has been installed in.
Attic insulation plays an important role in balancing temperature in extreme hot and cold months. It not only maintains a constant temperature in the indoor environment but also provides us some extra storage space.

>> The paper should always face you, that way you can staple it to the studs. It depends if your attic is finished and usable or unfinished and used for storing boxes. Always have the paper toward the living area, which in the case of an unfinished attic (insulating attic floor) would be paper face down. Make sure the first layer you put down on the floor of the attic has the vapor barrier (paper) face down with subsequent layers of unfaced (no paper) insulation. If the attic is finished (you plan on heating / cooling the space as an office or what not, then the paper would then face you when installed on the ceiling/roof and use unfaced in the floor. Also be sure to have a clear opening for your soffit vents so there is ample circulation. A product called a rafter vent is used to keep the insulation from blocking this area.
