Hi, All that (significantly) matters is the dew point. If the piano is colder than the due point for the relative humidity, then nothing good will come of treating it in this manner. If it is brought up to temperature slowly enough and the R.H. is low enough then there will be less damage. That's why I recommended super sealing the piano in plastic and then covering it it layers of blankets for insulation. Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.M.T., R.P.T.
