Saving Energy with Insulation
The furnace is running "full bore" and yet you feel a chill all the way down to your bones. There isn't a window open in the house, and the walls and ceilings are fully insulated. You simply can't figure out where the cold is coming from.
Well, if your home is 20 years old, or older, you may need to perform a little maintenance on your insulation. And the attic is the first place you should look. Believe it or not, most heat is lost through the ceiling -- 60 percent or more. Heat rises. Walls account for about 20 to 30 percent of the heat loss, with the rest escaping through the floor. Properly maintained insulation can significantly reduce this heat loss.
