How efficient to throw insulation in attic randomly?
My brother-in-law claimed that throwing additional insulation randomly in attic could cut the energy bill in half.
Of course, I believe that yes more insulation the better, but you don't just THROW insulation RANDOMLY all over the place in attic, right? At least putting the addition insulation on top of where the existing insulation, if I were to do it. How would you do it?
Does it really cut the energy in half by doing so/.
