| So, adding insulation to your attic floor will help. You should have enough insulation in your attic floor to give you R-49 (or you don't live in an area where ice-dams are a problem). That is about 20 inches of fiberglass. It means giving up the attic floor as a place to store things, since to get that much insulation you will have to go deeper than the joists, and preferrably lay it perpindicular to the joists. You should NOT use insulation with a vapor barrier (kraft faced) since you should not add a vapor barrier part way through your insulation. Before laying the insulation down, or before blowing it in, seal up any openings in the floor. Electrical wiring comes through holes, caulk them closed. The plumbing vent lines runn through the attic... caulk around those pipe openings. If you have light fixtures which require the insulation to be left away from them to dissipate the heat, then make sure you do that... you don't need to create a fire hazard here.|
At the eaves, make sure the insulation does NOT close off the opening between the rafters that allow the air to flow up from the eave (soffit) vents. If you are blowing in insulation or packing the batts in tight there, buy prop vents. These are styrofoam panels that fit between the rafters to keep a channel open.
Ok.. you are stopping the heat from escaping into the attic.. That is good just to save on your heating bill as well as help to eliminate ice dams. Now lets talk about...ventilation
