Well, I know I should have done this years ago, but just today finished upgrading my attic insulation from R13 (with several spots with no insulation), to at least R43 by adding new unfaced R30 on top of my existing stuff, run in the opposite direction. It'll be interesting to see how much my wood consumption goes down. I have noticed already that the house seems to be warmer in the morning than it otherwise would have been (i.e. it holds the heat better), but without adjusting for weather conditions I can't really say for sure.
Any guesses on the percentage of wood this upgrade will save me?
PS: Anyone planning on adding insulation, Home Depot is having a great deal on R30 unfaced rolls, 25' long, by 16" wide rolls for $9.37 each...haven't seen prices like that in a while.
