Hey guys, I introduced myself in another thread but I am a 29 year old fairly new homeowner who took over an old colonial style house that was built in 1922....with not a DROP of insulation. My wife and I moved in early December 2010 and froze our asses off for a month....while bleeding our oil tank dry after only a month.
Long story short, I began in the attic around January 2011 laying 6" of R-19 in between the floor joists. I noticed that helped....but still wasnt enough. I went back around February and rolled out an extra 9" of R-30 rolls I believe it was. A combined amount of 15" and that made a HUUUUGE difference. Our oil heat was reduced by more than half...it is actually closer to 1/3 of the cost because the boiler only kicks on 1/3 of the frequency it used to. Insulation paid for itself in the first year! Nasty job but mucho important
Also, dont forget to insulate your crawlspace if you have one....that was the icing on the cake for us! Laid down a tough 5mil plastic covering the dirt...and 9" of R-30 covering all 4 walls.
