If there is an attic you will be well insulated if you use blown-in cellulose. You will need about 300 cubic feet of blown in cellulose for an attic. If it's 2x10 rafters you will need about 336 square feet of 2x10 insulation blankets that are the width of the space between your rafters. If it's 24 inch on center rafters, you will need 24 inch blankets. You will need about 660 square feet of insulation for the walls, less the area of the doors and windows.

Fiberglass and cellulose insulation work by slowing down heat transfer from one source to another. That's why the thicknesses of those insulation's are crucial for performance. Also, fiberglass and cellulose only resist heat transfer, they don't block or reflect it so it eventually escapes through. Perforated radiant barrier can be installed over top of existing attic insulation to form a reflective cover to enhance your other insulation. 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. - EcoFoil
