Christopher Columbus discovered America while looking for India
British mismanagement of the 13 colonies which brought about the formation of the USA, the greatest nation of all time!
The forming of Christianity
First af all the Kraft facing on the insulation should always be installed towards the heated sideIt's purpose is to provide a vapor barrier so condensation will not formOlder insulation from 30-40 years ago sometimes had Kraft on both sidesCheck yours by peeling back a small areaIf you only have Kraft on one side (the up side), it should be reinstalled correctlyIf it is more than 20 years old you may as well replace it anywayIf you're going to leave it in and go over it then use unfaced insulationWhat thickness? That depends on what you have nowGo for a total of 12If you have 3 now, add R-30 (10)6 now add R-19If you have room in the bay to lay it in do soif your existing insulation comes up to the top of the joists lay your new blanket perpendicular to itIf you have Central AC or a hot air system check your ductwork now alsoRun the unit and check for leaksDon't worry about the fanNever seen a problem like that.
