MTL_Inspet_Man Posted October 13, 2009 Report Share Posted October 13, 2009 Keep running across this type of insulation from time to time. It's white and looks like sheared wool. There are little white bits like rice in it. I assume its mineral wool. Please let me know and wht the ''R'' value of this is if anyone knows. Trying to make sure my charts are correct.
