attic insulation. The Department of Energy says the signs that you need to Air-seal and Insulate your attic are: drafty rooms, hot and cold rooms, ice dams, and dust, especially in rooms right below the attic. The best way to seal the attic is to remove the old insulation and start over. Every seam, wire hole, top plate, and pipe penetration, the list goes on, is exposed and can be sealed. The air-sealing effectiveness can be measured by a blower door test that measures before and after air-flow. Couple this with more insulation in your attic and you will be more comfortable, healthier, and save on your energy costs. It cannot get any better than that!
