Fay writes from Danville, Indiana: "I'M GOING TO INSTALL INSULATION IN MY ATTICS SIDE WALLS (THE END GABELS). SHOULD I USE FACED OR UNFACED INSULATION?"

Answer: Is the attic you are planning to insulate finished and heated? If not, and it is simply unheated storage space, there is no value in adding insulation to the walls at the ends.

Instead, consider adding more insulation to the layer on the floor of the attic if it isn't already up to the recommended level for your area. Your local code officials can tell you what is recommended in your home. The U.S. Department of Energy recommends R-49 for most areas of the United States.
