I am removing the aluminum siding from my 1919 bungalow. The original cedar shingles underneath are in good condition, I will repaint/restore the trim boards. There is no insulation in the houses walls though and I am considering having blown in fiberglass insulation installed. The question of moisture keeps coming up and I can't seem to get a definative answer. There is no vapor barrier in the house and in this climate (CT) I really would like to have the insulation but have no way to install a vapor barrier. The problem of moisture condensing in the insulation seems to be real, yet no source says whether it is a high risk or a minimal problem. I would like some feedback from others who have had this work done and especially from an insulation pro who can give me an objective opinion.
